Walking or running: for the same distance, which consumes more energy?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/clement-lemineur-1529211">Clément Lemineur</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>; <a href="https://theconversation.com/profiles/clement-naveilhan-1495411">Clément Naveilhan</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>, and <a href="https://theconversation.com/profiles/francois-dernoncourt-1495410">François Dernoncourt</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a></em></p> <p>It’s Monday morning, the alarm goes off and it’s already 7:30 a.m. – and you’re 30 minutes late. Normally you need 45 minutes to walk the 3 kilometres to work, but this morning you’ll be running for 20 minutes. Yes, but by lunchtime you’re feeling more tired and you have the impression that you’ve expended more energy than usual on the trip. Yet you’ve covered the same distance as on the other days. How can this be?</p> <p>The calorie expenditure associated with any activity is called the “metabolic cost”, and corresponds to the energy consumed by our organs to cover a given distance. This metabolic cost can be determined by analysing the oxygen our bodies consume and the carbon dioxide they produce, we can estimate the amount of energy expended, and thus the metabolic cost. It was using this method that <a href="https://pubmed.ncbi.nlm.nih.gov/692303/">researchers had already answered our question back in the 1970s</a>.</p> <p>Perhaps not surprisingly, running consumes more energy than walking for the same distance covered. But why?</p> <h2>Energy lost when running</h2> <p>Imagine you’re watching someone running. Now look closely at the vertical movement (up and down) of their pelvis and head. As you can see from the diagram below, when we run, the distance that our body moves up and down is greater than when we walk. To produce this vertical movement, the muscles of the lower limbs have to generate more force, and that consumes more energy, yet doesn’t bring us any closer to our destination. So when running, part of the energy expended is used to move our bodies <a href="https://pubmed.ncbi.nlm.nih.gov/16029949/">upward rather than forward</a>. The energy needed to cover those 3 km is therefore higher for running than for walking.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=287&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=287&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=287&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=361&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=361&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=361&amp;fit=crop&amp;dpr=3 2262w" alt="Illustration of the oscillations of running and walking" /></a><figcaption><span class="caption">Running involves much greater vertical oscillation of the centre of mass than walking. This is the main reason why running consumes more energy than walking for the same distance covered.</span> <span class="attribution"><span class="source">François Dernoncourt</span>, <span class="license">Fourni par l'auteur</span></span></figcaption></figure> <p>This difference between walking and running is not confined to what happens during the activity itself. In fact, each physical exercise causes a delayed expenditure of energy, which is added to the expenditure during the activity.</p> <p>Taking this into account, it’s once again running that uses more energy than walking. Immediately after running your 3 km, the increased energy consumption (compared with resting) lasts for several minutes, mainly because of the increase in body temperature and the replenishment of energy reserves. This additional expenditure after running is <a href="https://pubmed.ncbi.nlm.nih.gov/22446673/">more than twice that observed after walking</a>, due to the difference in intensity between the two exercises.</p> <h2>It all depends on speed</h2> <p>Running therefore involves a higher calorie expenditure than walking for the same distance covered. But this is on condition that the walking speed considered is “normal” (around 5 km/h). So, if we walk very slowly, it will take us so long to cover the 3 km that the calorie expenditure will be greater in the end. This is because the body expends a certain amount of energy per unit of time no matter what, regardless of the activity performed (known as the “basal metabolic rate”).</p> <p>The same applies if the walking speed is very fast (<a href="https://pubmed.ncbi.nlm.nih.gov/29925582/">more than 8 km/h</a>): running is more energy-efficient. Here, the coordination required to walk at such a speed means that we need to activate our muscles more, without being able to take advantage of the elasticity of our tendons, as is the case with running.</p> <p>Moreover, we have a very precise intuitive perception of the energy efficiency of a particular style of movement. If we’re on a treadmill whose speed gradually increases, the point at which we spontaneously switch from walking to running coincides with the <a href="https://www.sciencedirect.com/science/article/pii/S096663622100120X">moment when it would become more energy-consuming to walk than to run</a>.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=395&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=395&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=395&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=497&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=497&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=497&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Modelling of metabolic cost (kilocalories expended per kilogram per kilometre covered) as a function of speed (kilometres per hour) for walking and running.

Walking can prevent low back pain, a new study shows

If you do, you’re not alone. Roughly <a href="https://pubmed.ncbi.nlm.nih.gov/31208917/">70% of people</a> who recover from an episode of low back pain will experience a new episode in the following year.</p> <p>The recurrent nature of low back pain is a major contributor to the <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00098-X/fulltext">enormous burden</a> low back pain places on individuals and the health-care system.</p> <p>In our new study, published today in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00755-4/fulltext">The Lancet</a>, we found that a program combining walking and education can effectively reduce the recurrence of low back pain.</p> <h2>The WalkBack trial</h2> <p>We randomly assigned 701 adults who had recently recovered from an episode of low back pain to receive an individualised walking program and education (intervention), or to a no treatment group (control).</p> <p>Participants in the intervention group were guided by physiotherapists across six sessions, over a six-month period. In the first, third and fifth sessions, the physiotherapist helped each participant to develop a personalised and progressive walking program that was realistic and tailored to their specific needs and preferences.</p> <p>The remaining sessions were short check-ins (typically less than 15 minutes) to monitor progress and troubleshoot any potential barriers to engagement with the walking program. Due to the COVID pandemic, most participants received the entire intervention via telehealth, using video consultations and phone calls.</p> <p>The program was designed to be manageable, with a target of five walks per week of roughly 30 minutes daily by the end of the six-month program. Participants were also encouraged to continue walking independently after the program.</p> <p>Importantly, the walking program was combined with education provided by the physiotherapists during the six sessions. This education aimed to give people a better understanding of pain, reduce fear associated with exercise and movement, and give people the confidence to self-manage any minor recurrences if they occurred.</p> <p>People in the control group received no preventative treatment or education. This reflects what <a href="https://www.sciencedirect.com/science/article/abs/pii/S2468781222001308?via%3Dihub">typically occurs</a> after people recover from an episode of low back pain and are discharged from care.</p> <h2>What the results showed</h2> <p>We monitored the participants monthly from the time they were enrolled in the study, for up to three years, to collect information about any new recurrences of low back pain they may have experienced. We also asked participants to report on any costs related to their back pain, including time off work and the use of health-care services.</p> <p>The intervention reduced the risk of a recurrence of low back pain that limited daily activity by 28%, while the recurrence of low back pain leading participants to seek care from a health professional decreased by 43%.</p> <p>Participants who received the intervention had a longer average period before they had a recurrence, with a median of 208 days pain-free, compared to 112 days in the control group.</p> <p>Overall, we also found this intervention to be cost-effective. The biggest savings came from less work absenteeism and less health service use (such as physiotherapy and massage) among the intervention group.</p> <p>This trial, like all studies, had some limitations to consider. Although we tried to recruit a wide sample, we found that most participants were female, aged between 43 and 66, and were generally well educated. This may limit the extent to which we can generalise our findings.</p> <p>Also, in this trial, we used physiotherapists who were up-skilled in health coaching. So we don’t know whether the intervention would achieve the same impact if it were to be delivered by other clinicians.</p> <h2>Walking has multiple benefits</h2> <p>We’ve all heard the saying that “prevention is better than a cure” – and it’s true. But this approach has been largely neglected when it comes to low back pain. Almost all <a href="https://www.sciencedirect.com/science/article/pii/S0140673618304896?via%3Dihub">previous studies</a> have focused on treating episodes of pain, not preventing future back pain.</p> <p>A limited number of <a href="https://pubmed.ncbi.nlm.nih.gov/26752509/">small studies</a> have shown that exercise and education can help prevent low back pain. However, most of these studies focused on exercises that are not accessible to everyone due to factors such as high cost, complexity, and the need for supervision from health-care or fitness professionals.</p> <p>On the other hand, walking is a free, accessible way to exercise, including for people in rural and remote areas with limited access to health care.</p> <p>Walking also delivers many other <a href="https://www.vichealth.vic.gov.au/sites/default/files/VH_Benefits-of-Walking-Summary2020.pdf">health benefits</a>, including better heart health, improved mood and sleep quality, and reduced risk of several chronic diseases.</p> <p>While walking is not everyone’s favourite form of exercise, the intervention was well-received by most people in our study. Participants <a href="https://pubmed.ncbi.nlm.nih.gov/37271689/">reported</a> that the additional general health benefits contributed to their ongoing motivation to continue the walking program independently.</p> <h2>Why is walking helpful for low back pain?</h2> <p>We don’t know exactly why walking is effective for preventing back pain, but <a href="https://www.e-jer.org/journal/view.php?number=2013600295">possible reasons</a> could include the combination of gentle movements, loading and strengthening of the spinal structures and muscles. It also could be related to relaxation and stress relief, and the release of “feel-good” endorphins, which <a href="https://my.clevelandclinic.org/health/body/23040-endorphins">block pain signals</a> between your body and brain – essentially turning down the dial on pain.</p> <p>It’s possible that other accessible and low-cost forms of exercise, such as swimming, may also be effective in preventing back pain, but surprisingly, <a href="https://pubmed.ncbi.nlm.nih.gov/34783263/">no studies</a> have investigated this.</p> <p>Preventing low back pain is not easy. But these findings give us hope that we are getting closer to a solution, one step at a time.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231682/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/tash-pocovi-1293184">Tash Pocovi</a>, Postdoctoral research fellow, Department of Health Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/christine-lin-346821">Christine Lin</a>, Professor, Institute for Musculoskeletal Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/mark-hancock-1463059">Mark Hancock</a>, Professor of Physiotherapy, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/petra-graham-892602">Petra Graham</a>, Associate Professor, School of Mathematical and Physical Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/simon-french-713564">Simon French</a>, Professor of Musculoskeletal Disorders, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Here’s what the evidence says about three of the most common misconceptions.</p> <h2>Myth 1: people on parole walk free</h2> <p>Parole is the conditional release of an incarcerated person (parolee) by a parole board authority, after they have served their non-parole period (minimum sentence) in jail. This isn’t always reflected in headlines.</p> <p><a href="https://www.9news.com.au/national/snowtown-murders-bodies-in-barrels-murders-mark-haydon-release-south-australia/f4b62a72-ec3d-4238-94d2-64697fbcdef3">Some coverage</a> suggests people on parole are released early and “walk free” without conditions. This is not true.</p> <p>According to the <a href="https://www.adultparoleboard.vic.gov.au/what-parole/purpose-and-benefits">Adult Parole Board of Victoria</a>: "Parole provides incarcerated people with a structured, supported and supervised transition so that they can adjust from prison back into the community, rather than returning straight to the community at the end of their sentence without supervision or support."</p> <p>Parole comes with strict conditions and requirements, such as curfews, drug and alcohol testing, electronic monitoring, program participation, to name a few.</p> <p>People with experience of parole highlight its punitivism and continued extension of surveillance.</p> <h2>Myth 2: most parolees reoffend</h2> <p>Another myth is that the likelihood all parolees reoffend is high. Research over a number of years has consistently found parole reduces reoffending.</p> <p>For example, <a href="https://journals.sagepub.com/doi/abs/10.1177/0004865815585393?journalCode=anja">a 2016 study in New South Wales</a> found at the 12 month mark, a group of parolees reoffended 22% less than an unsupervised cohort.</p> <p>A <a href="https://www.bocsar.nsw.gov.au/Publications/CJB/2022-Report-Effect-of-parole-supervision-on-recidivism-CJB245.pdf">2022 study</a> by the NSW Bureau of Crime Statistics and Research found parole was especially successful in reducing serious recidivism rates among incarcerated people considered to be at a high risk of reoffending.</p> <p>More recently in Victoria, <a href="https://www.adultparoleboard.vic.gov.au/system/files/inline-files/Adult%20Parole%20Board%20Annual%20Report%202022-23_0.pdf">the Adult Parole Board</a> found over 2022–23, no parolees were convicted of committing serious offences while on parole.</p> <p>In contrast, unstructured and unconditional release increases the risk of returning to prison.</p> <h2>Myth 3: parole is easy to get</h2> <p>While the number of parolees reoffending has dropped, so too has the total number of people who are exiting prison on parole.</p> <p>Over a decade ago, Victoria underwent significant parole reforms, largely prompted by high-profile incidents and campaigns. In just five years following Jill Meagher’s tragic death in 2012, the Victorian government passed <a href="https://www.tandfonline.com/doi/full/10.1080/10345329.2018.1556285">13 laws reshaping parole</a>.</p> <p>The result is the number of people on parole in Victoria has halved since 2012, despite incarceration numbers remaining steady.</p> <p><iframe id="maNRy" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/maNRy/" width="100%" height="400px" frameborder="0"></iframe></p> <p>These reforms have made it more difficult for people convicted of serious offences to get parole, as well as preventing individuals or specific groups from being eligible for parole (such as police killers, <a href="https://theconversation.com/no-body-no-parole-laws-could-be-disastrous-for-the-wrongfully-convicted-191083">“no body, no parole” prisoners</a>, and certain high-profile murderers).</p> <p>Similar laws can be found in other states. For example, no body, no parole was introduced in all other Australian states and territories, except for Tasmania and the Australian Capital Territory.</p> <p>As a consequence, more people are being released at the end of their full sentence. This can be detrimental not only for the incarcerated person but the wider community, because they are not receiving the reintegration support parole provides.</p> <p>Aside from restricted access due to political intervention, parole is facing a new crisis, which has nothing to do with eligibility or suitability.</p> <p>Last year, 40% of Victorian parole applications were denied, often due to reasons <a href="https://www.adultparoleboard.vic.gov.au/system/files/inline-files/Adult%20Parole%20Board%20Annual%20Report%202022-23_0.pdf">unrelated to suitability</a>.</p> <p>Housing scarcity played a significant role, with 59% of rejections (or 235 applications) citing a lack of suitable accommodation as one of the reasons parole was denied. This is playing out <a href="https://www.abc.net.au/news/2023-08-11/women-on-bail-parole-increased-risk-of-homelessness-qld/102717002">across the country</a>.</p> <p>Parole is vulnerable to community and media hype, and political knee-jerk reactions in response to high profile incidents involving a person on parole. Because of the actions of a few, parole as a process has been restricted for many.</p> <p>While the wider community are active in advocacy efforts to restrict parole from certain people or groups (for example, this petition for <a href="https://www.change.org/p/lyns-law-no-body-no-parole">Lyn’s Law in NSW</a>), public efforts to restrict parole seem at odds with its purposes.</p> <p>Despite this, research suggests when the public are educated about the purposes and intent of parole, they are more likely to be <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3125829">supportive of it</a>.</p> <p>The susceptibility of parole to media and community influence results in frequent, impactful changes affecting individuals inside and outside prisons. Headlines such as “walking free” have the potential to mislead the public on the purpose and structure of parole. Coverage should portray parole beyond mere early termination of a sentence by accurately reflecting its purpose and impact.<!-- Below is The Conversation's page counter tag.

Only walking for exercise? Here’s how to get the most out of it

<p><em><a href="https://theconversation.com/profiles/ken-nosaka-169021">Ken Nosaka</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>We’re living longer than in previous generations, with <a href="https://www.aihw.gov.au/reports/older-people/older-australians/contents/demographic-profile">one in eight</a> elderly Australians now aged over 85. But the current <a href="https://pubmed.ncbi.nlm.nih.gov/26561272/">gap</a> between life expectancy (“lifespan”) and health-adjusted life expectancy (“healthspan”) is about ten years. This means many of us live with significant health problems in our later years.</p> <p>To increase our healthspan, we need planned, structured and regular physical activity (or exercise). The <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">World Health Organization recommends</a> 150–300 minutes of moderate-intensity exercise – such as brisk walking, cycling and swimming – per week and muscle strengthening twice a week.</p> <p>Yet few of us meet these recommendations. <a href="https://doi.org/10.1186/s12966-019-0797-2">Only 10%</a> meet the strength-training recommendations. <a href="https://pubmed.ncbi.nlm.nih.gov/32488898/">Lack of time</a> is one of the most common reasons.</p> <p>Walking is cost-effective, doesn’t require any special equipment or training, and can be done with small pockets of time. <a href="https://link.springer.com/epdf/10.1007/s00421-024-05453-y?sharing_token=1vDsDJTN5WzPxi5YmSEkOfe4RwlQNchNByi7wbcMAY5hnPeFvF3FY4v2z1P9M2M0oiR78kXv1Yzj0ODMgckqhKOGHUABEd9UOPOfV5kPAj1jf1IYMIYkdIBv-DUEcKCOiDdNyj6MFypeDhSyeYQrWu_bvlAYtPUmOSaldFpmycA%3D">Our preliminary research</a>, published this week, shows there are ways to incorporate strength-training components into walking to improve your muscle strength and balance.</p> <h2>Why walking isn’t usually enough</h2> <p>Regular walking <a href="http://theconversation.com/health-check-in-terms-of-exercise-is-walking-enough-78604">does not appear</a> to work as muscle-strengthening exercise.</p> <p>In contrast, exercises consisting of “eccentric” or muscle-lengthening contractions <a href="http://theconversation.com/its-ok-to-aim%20lower-with-your-new-years-exercise-resolutions-a-few-minutes-a-day-can-improve-your-muscle-strength-193713">improve</a> muscle strength, <a href="https://pubmed.ncbi.nlm.nih.gov/31130877/">prevent muscle wasting</a> and improve other functions such as balance and flexibility.</p> <p>Typical eccentric contractions are seen, for example, when we sit on a chair slowly. The front thigh muscles lengthen with force generation.</p> <h2>Our research</h2> <p>Our <a href="https://pubmed.ncbi.nlm.nih.gov/31055678/">previous research</a> found body-weight-based eccentric exercise training, such as sitting down on a chair slowly, improved lower limb muscle strength and balance in healthy older adults.</p> <p>We also <a href="https://pubmed.ncbi.nlm.nih.gov/28291022/">showed</a> walking down stairs, with the front thigh muscles undergoing eccentric contractions, increased leg muscle strength and balance in older women more than walking up stairs. When climbing stairs, the front thigh muscles undergo “concentric” contractions, with the muscles shortening.</p> <p>It can be difficult to find stairs or slopes suitable for eccentric exercises. But if they could be incorporated into daily walking, lower limb muscle strength and balance function could be improved.</p> <p>This is where the idea of “eccentric walking” comes into play. This means inserting lunges in conventional walking, in addition to downstairs and downhill walking.</p> <figure><iframe src="https://www.youtube.com/embed/wAI7z3XdY9o?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Eccentric walking means incorporating deep lunges into your movement.</span></figcaption></figure> <p>In our <a href="https://link.springer.com/epdf/10.1007/s00421-024-05453-y?sharing_token=1vDsDJTN5WzPxi5YmSEkOfe4RwlQNchNByi7wbcMAY5hnPeFvF3FY4v2z1P9M2M0oiR78kXv1Yzj0ODMgckqhKOGHUABEd9UOPOfV5kPAj1jf1IYMIYkdIBv-DUEcKCOiDdNyj6MFypeDhSyeYQrWu_bvlAYtPUmOSaldFpmycA%3D">new research</a>, published in the European Journal of Applied Physiology, we investigated the effects of eccentric walking on lower limb muscle strength and balance in 11 regular walkers aged 54 to 88 years.</p> <p>The intervention period was 12 weeks. It consisted of four weeks of normal walking followed by eight weeks of eccentric walking.</p> <p>The number of eccentric steps in the eccentric walking period gradually increased over eight weeks from 100 to 1,000 steps (including lunges, downhill and downstairs steps). Participants took a total of 3,900 eccentric steps over the eight-week eccentric walking period while the total number of steps was the same as the previous four weeks.</p> <p>We measured the thickness of the participants’ front thigh muscles, muscle strength in their knee, their balance and endurance, including how many times they could go from a sitting position to standing in 30 seconds without using their arms. We took these measurements before the study started, at four weeks, after the conventional walking period, and at four and eight weeks into the eccentric walking period.</p> <p>We also tested their cognitive function using a digit symbol-substitution test at the same time points of other tests. And we asked participants to complete a questionnaire relating to their activities of daily living, such as dressing and moving around at home.</p> <p>Finally, we tested participants’ blood sugar, cholesterol levels and complement component 1q (C1q) concentrations, a potential <a href="https://faseb.onlinelibrary.wiley.com/doi/abs/10.1096/fj.14-262154">marker of sarcopenia</a> (muscle wasting with ageing).</p> <h2>What did we find?</h2> <p>We found no significant changes in any of the outcomes in the first four weeks when participants walked conventionally.</p> <p>From week four to 12, we found significant improvements in muscle strength (19%), chair-stand ability (24%), balance (45%) and a cognitive function test (21%).</p> <p>Serum C1q concentration decreased by 10% after the eccentric walking intervention, indicating participants’ muscles were effectively stimulated.</p> <p>The sample size of the study was small, so we need larger and more comprehensive studies to verify our findings and investigate whether eccentric walking is effective for sedentary people, older people, how the different types of eccentric exercise compare and the potential cognitive and mental health benefits.</p> <p>But, in the meantime, “eccentric walking” appears to be a beneficial exercise that will extend your healthspan. It may look a bit eccentric if we insert lunges while walking on the street, but the more people do it and benefit from it, the less eccentric it will become. <!-- Below is The Conversation's page counter tag.

How 22 minutes of exercise a day could reduce the health risks from sitting too long

<p><em><a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>People in developed countries spend an average of <a href="https://doi.org/10.1136/bjsports-2022-106568">nine to ten hours</a> a day sitting. Whether it’s spending time in front of a computer, stuck in traffic, or unwinding in front of the TV, our lives have become increasingly sedentary.</p> <p>This is concerning because prolonged time spent sitting is <a href="https://bjsm.bmj.com/content/54/24/1451?s=09&amp;int_source=trendmd&amp;int_medium=cpc&amp;int_campaign=usage-042019">linked to a number of health issues</a> including obesity, heart disease, and certain types of cancers. These health issues can contribute to earlier death.</p> <p>But a <a href="https://doi.org/10.1136/bjsports-2022-106568">new study</a> suggests that for people over 50, getting just 22 minutes of exercise a day can lower the increased risk of premature death from a highly sedentary lifestyle.</p> <h2>What the researchers did</h2> <p>The team combined data from two studies from Norway, one from Sweden and one from the United States. The studies included about 12,000 people aged 50 or older who wore wearable devices to track how active and sedentary they were during their daily routines.</p> <p>Participants were followed up for at least two years (the median was 5.2 years) during the study period, which spanned 2003-2020.</p> <p>Analyses took several lifestyle and health factors into account, such as education, alcohol intake, smoking status, and previous history of heart disease, cancer and diabetes. All this data was linked to national death registries.</p> <h2>A 22 minute threshold</h2> <p>A total of 805 participants died during follow up. The researchers found people who were sedentary for more than 12 hours a day had the highest risk of death (a 38% higher risk than people who were sedentary for eight hours).</p> <p>However, this was only observed in those who did less than 22 minutes of moderate to vigorous physical activity daily. So for people who did more than 22 minutes of exercise, there was no longer a significantly heightened risk – that is, the risk became generally similar to those who were sedentary for eight hours.</p> <p>Higher daily duration of physical activity was consistently associated with lower risk of death, regardless of total sedentary time. For example, the team reported an additional ten minutes of moderate to vigorous physical activity each day could lower mortality risk by up to 15% for people who were sedentary less than 10.5 hours a day. For those considered highly sedentary (10.5 hours a day or more), an additional ten minutes lowered mortality risk by up to 35%.</p> <h2>The study had some limitations</h2> <p>The team couldn’t assess how changes in physical activity or sedentary time over several months or years may affect risk of death. And the study included only participants aged 50 and above, making results less applicable to younger age groups.</p> <p>Further, cultural and lifestyle differences between countries may have influenced how data between studies was measured and analysed.</p> <p>Ultimately, because this study was observational, we can’t draw conclusions on cause and effect with certainty. But the results of this research align with a growing body of evidence exploring the relationship between physical activity, sedentary time, and death.</p> <h2>It’s positive news</h2> <p>Research has previously suggested <a href="https://bjsm.bmj.com/content/54/24/1499">physical activity may offset</a> health risks associated with <a href="https://www.jacc.org/doi/abs/10.1016/j.jacc.2019.02.031">high sedentary time</a>.</p> <p>The good news is, even short bouts of exercise can have these positive effects. In this study, the 22 minutes wasn’t necessarily done all at once. It was a total of the physical activity someone did in a day, and would have included incidental exercise (activity that’s part of a daily routine, such as climbing the stairs).</p> <p>Several studies using wearable devices have found short bursts of high-intensity everyday activities such as stair climbing or energetic outdoor home maintenance activities such as mowing the lawn or cleaning the windows can lower <a href="https://www.nature.com/articles/s41591-022-02100-x">mortality</a>, <a href="https://academic.oup.com/eurheartj/article/43/46/4801/6771381">heart disease</a> and <a href="https://jamanetwork.com/journals/jamaoncology/fullarticle/2807734">cancer</a> risk.</p> <p>A recent study using wearable devices found moderate to vigorous bouts of activity <a href="https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(23)00183-4/fulltext">lasting three to five minutes</a> provide similar benefits to bouts longer than ten minutes when it comes to stroke and heart attack risk.</p> <p>Several other studies have found <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">being active just on the weekend</a> provides similar health benefits as <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2794038">being active throughout the week</a>.</p> <p>Research has also shown the benefits of <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2795819">physical activity</a> and <a href="https://jamanetwork.com/journals/jama/article-abstract/2809418">reducing sedentary time</a> extend to cognitive health.</p> <p>Routines such as desk jobs can foster a sedentary lifestyle that may be difficult to shift. But mixing short bursts of activity into our day can make a significant difference towards improving our health and longevity.</p> <p>Whether it’s a brisk walk during lunch, taking the stairs, or even a short at-home workout, this study is yet another to suggest that every minute counts.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/216259/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, Postdoctoral Research Fellow, Faculty of Medicine and Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, Professor of Physical Activity, Lifestyle, and Population Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Surprise! Scientists find falls likely when texting and walking

<p>It seems obvious that texting while walking is <a href="https://cosmosmagazine.com/people/behaviour/millennials-most-likely-to-text-and-drive/" target="_blank" rel="noreferrer noopener">risky</a> business.

I wondered: is this safe?” said senior author Dr Matthew Brodie, a neuroscientist and engineer at the University of New South Wales.</p> <p>“This has made me want to investigate the dangers of texting while walking. I wanted to know if these dangers are real or imagined and to measure the risk in a repeatable way.”</p> <p>Brodie and colleagues recruited 50 undergraduate students from UNSW to take part in the study.</p> <p>Participants walked across a specially built tiled surface, fitted with a tile that could slip out halfway through.</p> <p>They were asked to either walk across the surface normally, or walk across it while texting “the quick brown fox jumps over the lazy dog”.</p> <p>The students were strapped to safety harnesses so they couldn’t fall, and told they may or may not slip.</p> <div style="position: relative; display: block; max-width: 100%;"> <div style="padding-top: 56.25%;"><iframe style="position: absolute; top: 0px; right: 0px; bottom: 0px; left: 0px; width: 100%; height: 100%;" src="https://players.brightcove.net/5483960636001/HJH3i8Guf_default/index.html?videoId=6332776122112" allowfullscreen="allowfullscreen"></iframe></div> </div> <p class="caption"><em>The methods used in the experiment.

Others sped up in anticipation of slipping. Such different approaches reinforce how no two people are the same, and to better prevent accidents from texting while walking, multiple strategies may be needed.”</p> <p>The researchers recorded motion data from the students as they moved and slipped, analysing how stable they were.</p> <p>They found that texting while walking made the students significantly less stable.</p> <p>Specifically, the students “trunk angle” – the angle of their torsos – varied more when they were slipping while texting. This means they were less stable.</p> <p>Participants were also less accurate texters when they did it while walking as opposed to sitting down, and least accurate when they did slip over.</p> <p>“Pedestrians should therefore be discouraged through new educational and technology-based initiatives (for example a ‘texting lock’ on detection of walking) from texting while walking on roadside footpaths and other environments where substantial hazards to safety exist,” conclude the researchers in their paper.</p> <p><em>Image credits: Shutterstock</em></p> <p><em><a href="https://cosmosmagazine.com/health/body-and-mind/texting-walking-falls/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/ellen-phiddian/">Ellen Phiddian</a>. </em></p> </div>

Here’s why you need to go for a walk every single day

<p><strong>The benefits of walking every day </strong></p> <p>Twenty summers ago, Nancy Duguay stood at the side of a soccer pitch in watching her 11-year-old son sprint back and forth, and wished she had a cigarette.</p> <p>Duguay, then 39 and a cardiac-rehab nurse, was trying to quit smoking after having the habit for more than half her life. She’d sneaked her first cigarettes from her parents’ packs as a teen and hadn’t stopped since. With her hands empty as she waited for her son’s practice to end, the urge for a puff gnawed at her.</p> <p>Behind the field, the heavily forested Sugarloaf Mountain stood guard. As a kid, Duguay and her friends regularly hiked the mountain and picnicked on its peak.</p> <p>Then an idea struck her: walking instead of smoking. She told another parent that she would be back in time to pick up her son and then set off for the mountain. “In just my regular sneakers, a pair of shorts and a T-shirt,” she remembers.</p> <p>Duguay’s heart pounded as she climbed, and she stopped often to rest. When she arrived at the top, she took in the view that sweeps over the city and across the river to the rolling hills of the Gaspé Peninsula.</p> <p>“I just felt so good,” says Duguay. “My natural endorphins kicked in, and the craving was gone.”</p> <p>Almost every day since, she has gone for a walk – and the habit has changed her life. Not only did she quit smoking, but her resting heart rate dropped from 80 beats per minute to 60. The ritual has given her a lot more, as well: stress relief, mental-health management, and a sense of community.</p> <p>“There’s a psychological and physical need to do it now,” she says. “I want to keep healthy and keep moving.” Keep reading to discover more incredible health benefits of walking every day.</p> <p><strong>It's good for your body</strong></p> <p>A growing body of research confirms what Duguay discovered: there are enormous benefits in walking every day. According to a report from the Canadian Academy of Sport and Exercise Medicine, walking for 150 minutes a week can reduce the risk of most major chronic diseases by 25 to 50 per cent. In fact, light to moderate exercise has been found to be more effective than medication during rehabilitation after a stroke. For prevention of diabetes and as a secondary treatment of heart disease, walking is equally as effective as taking drugs.</p> <p>In 2019, a Journal of Clinical Oncology study reported that a small amount of physical activity – such as taking a brisk walk for 20 minutes or more a day – is linked to a lower risk of seven types of cancer. Meanwhile, more walking means better sleep, too. In a recent study of middle-aged men and women, the participants who took more steps during the day slept better at night.</p> <p>“We need to start thinking about walking as a healthy activity,” advises Dr Jane Thornton, a family physician in London, Ontario. She advocates for the idea that we consider physical activity as medicine – a philosophy that grew out of personal experience. Thornton was a shy, sedentary 14-year-old when she signed up for a beginner’s rowing class in Fredericton. While her physical fitness improved, a new social circle opened to her and her grades went up. Thornton went on to become a world-champion rower and represented Canada at the 2008 Olympics.</p> <p>A few years after competing in the Olympics and shortly before retiring from sport, she enrolled in medical school. She was surprised by the lack of information provided to physicians-in-training about the benefits of exercise. “For whatever reason, there just wasn’t any content at all on physical activity,” she says.</p> <p>In 2014, Thornton started working on a campaign with the Canadian Academy of Sport and Exercise Medicine to get doctors to prescribe physical activity for patients – including walking. “I don’t think it’s a panacea for everybody, but it is one of the easiest, best solutions we have at our disposal,” she says.</p> <p>One significant reason that walking is so good for us is fairly straightforward: when we move, our hearts work harder to transport blood to the working muscles and organs. That repeated effort strengthens the heart muscle, making it pump more efficiently at all times, sending blood around the body with fewer beats per minute. Exercise also improves the function of blood vessels, with one analysis reporting that aerobic exercise can improve our vascular health.</p> <p>Walking helps build other muscles, too, especially in the lower body, and improves balance and strength. Physiotherapists like to say “Motion is lotion.” When our bodies don’t move enough, they stiffen. Ligaments, tendons and muscles tighten when they’re not used, causing pain in joints. For back pain, especially, movement can help. When we walk, we activate the muscles that run along the spine, strengthening them. “Pain and function improve just by putting those muscles into play,” Thornton says.</p> <p>Hospitals have also begun to embrace the value of walking. At Mount Sinai in Toronto, older patients weren’t always encouraged to get up from bed because of the risk of falling. About ten years ago, that changed. Assisted by doctors, nurses and volunteers, patients are now prompted to walk to the bathroom, explore the hallways and get out of bed to eat their meals.</p> <p>Since that change, fewer patients require catheters and suffer pressure ulcers. On average, they spend less time in the hospital. “Every day that an older person is in bed, they lose five per cent of their physical functioning,” says Dr Samir Sinha, Mount Sinai Hospital’s director of geriatrics. “So getting them up and walking can reduce the chance that grandma might not be able to return home.”</p> <p><strong>It's good for your mental health </strong></p> <p>One of the most important benefits of walking every day is that it’s equally beneficial for our mental health. For Duguay, walking helped her through some of the toughest periods in her life. When her mother died of cancer, Duguay turned to the mountain to walk through her pain. “I would cry all the way up the mountain,” she remembers. In this way, walking became her antidepressant.</p> <p>According to a 2019 study led by researchers at Harvard University, people with a genetic risk for depression are less likely to struggle with the condition if they exercise – even performing light physical activity like walking.</p> <p>Walking also reduces the risk of dementia and Alzheimer’s disease. In 2019, the World Health Organization released new guidelines on dementia prevention, and its top recommendation was to get more exercise.</p> <p>“We’ve always known that exercise is good for your heart, but we’re now making a connection between exercise and cognitive improvements,” said Dr Saskia Sivananthan, chief research &amp; knowledge, translation and exchange officer at the Alzheimer Society of Canada.</p> <p>Although that link isn’t yet fully understood, Sivananthan says there are a number of possible explanations: increased blood flow to the brain increases the organ’s cell growth; physical activity stimulates certain hormones that improve well-being and may reduce brain-matter loss linked to cognitive function; and walking might also reduce inflammation in the brain.</p> <p>Meanwhile, one study from McMaster University has shown that aerobic activity that incorporates intervals of higher-intensity exertion improves memory function. According to Dr Jennifer Heisz, who worked on the research, walking promotes production of a protein, BDNF, that spurs growth of new brain cells. These cells help us create high-fidelity memories – “the type we need every day to locate our car in a busy parking lot and recognise a friend in a crowd,” she said.</p> <p><strong>It's good for your social life</strong></p> <p>Jim Button, a 56-year-old entrepreneur, was diagnosed with kidney cancer in 2014. He underwent successful surgery but, less than two years later, he learned that his cancer was back, had spread and was terminal.</p> <p>Button knew that exercise would help keep him as healthy as possible. He started walking five kilometres a day. Before his diagnosis, he’d meet with business contacts and friends at coffee shops. Now he asks them to join him on a walk. Every day over the last three years that his health has allowed, Button has gone for a walk, all the while expanding the range of his walking partners – he regularly strolls with strangers who reach out to him seeking business advice, or people recently diagnosed with cancer and other illnesses.</p> <p>“I’ve discovered that not a lot of people go for walks,” Button says. “And when they do, it opens up their mind to be a bit more honest about whatever challenge they would like to talk about.” On some walks, he says, conversation never slows. On others, little is said but much is shared, even silently.</p> <p>Inspired by Button’s strolls, Dr Lisa Bélanger – founder of Knight’s Cabin, a Canadian charity for cancer survivors and their supporters – helped found an initiative in Calgary called Walk It Out. The program is like other peer support groups, but participants walk outside while they share their experiences with the disease. “More than in a sit-down, face-to-face meeting, walking seems to allow a conversation to flow naturally,” she says.</p> <p>Bélanger, who is an expert in behavioural medicine, adds that walking has the power to undo negative thought patterns. “If you’re thinking about a problem and you go for a walk, the activity in your brain changes, and you learn and think better,” she says.</p> <p>Like Button, Nancy Duguay has corralled her community around her daily walks. The more she walked, the more people around her saw the benefits and started doing it, too. Her husband, Roger, began to accompany her on hikes on their holidays. And about seven years after Duguay’s first walk up a nearby mountain, her sister decided to try it. Now she, too, takes a walk every day, and they often go together. A small community of walkers has formed around them.</p> <p>“We’ll meet people coming down and say, ‘This was a tough one today. It was really slippery, but boy, you know, it’s worth it.’”</p> <p><strong>Put your best food forwards</strong></p> <p>To experience all the benefits of walking every day, treat it like a workout, says personal-fitness trainer Korey Samuelson:</p> <p>Walk with an upright posture, your head held straight, not looking up or down. Keep your gaze about five metres ahead.</p> <p>To move faster, put more bend in your elbows.</p> <p>Swing your arms forwards and back; moving them across the body isn’t efficient. “Just like sprinting, arm movement is important for strong walking,” says Samuelson.</p> <p>When your lead foot lands on the ground, roll from heel to toe. Your footwear should be pliable enough to allow the natural movement across your foot.</p> <p>To speed up, increase your strides per minute rather than elongating your strides. More steps per minute means you’ll travel further, faster.</p> <p>Use Nordic walking poles to increase your heart rate and burn more calories.</p> <p>Intersperse intervals of brisk walking with periods at a slower pace.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/heres-why-you-need-to-go-for-a-walk-every-single-day" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Vets share their 5 best tips for safer dog walks – and 5 things never to do

<h2>Dogs need exercise</h2> <p>Dogs need physical exercise –  and as their owner, those daily steps add up for you, too. A 2017 study published in BMC Public Health found that dog owners walk an average of 22 extra minutes per day. That’s exercise that counts toward The Heart Foundation’s recommended 150 minutes a week of moderate-intensity exercise.</p> <p>Walking outside has some major health perks for you…and, says veterinarian, Dr Megan Conrad, regular walks provide excellent mental stimulation for your pooch.</p> <p>However, Dr Conrad and some fellow veterinarians told us there are some definite do’s and don’ts of dog walking that’ll help keep you and your pup safe and strolling happily for ages to come.</p> <h2>Do: Know your dog’s walking needs</h2> <p>In general, daily walks are recommended for most dogs, Dr Conrad says. Still, “the length of your walk very much depends on breed, age, and overall physical health.” A young border collie can go for several kilometres, while an older mini poodle is likely to need a shorter walk.</p> <p>The average adult dog needs about 20 to 45 minutes of moderate exercise twice a day, which can include a brisk walk, says veterinarian, Dr Whitney Miller. But, Dr Miller says, it’s a good idea to check with your pet’s veterinarian to determine his or her individual exercise needs.</p> <h2>Don’t: Walk too much too soon</h2> <p>“Just like we would not go out and run a marathon without training first,  you cannot expect your dog to go long distances right away,” Dr Karwacki says. When you’re establishing a walking routine, go short distances first and see how your dog is doing before you tack on more mileage.</p> <h2>Do: Make adjustments for the weather</h2> <p>“The general rule is if it’s too hot or too cold for you to be outside, it’s too much for your dog as well,” says veterinarian Dr Amber Karwacki.</p> <p>This is especially true for breeds like French bulldogs, pugs, or Boston terriers that don’t handle high temperatures well. One way around the heat is to aim for early morning or nighttime walks – just make sure to equip yourself and your dog with high-visibility gear like reflective clothing and lights (and carry a torch!).</p> <p>If possible, choose an area or route that allows your dog to walk on soft grass or dirt, as this helps prevent damage to their paw pads, Dr Miller says. “If you are walking on cold ground, booties can help prevent your pet’s paws from injury, keep snow and ice from getting stuck between the pads, and provide a barrier against ice melt,” she adds.</p> <p>If you’re walking on pavement during the summer, using paw protection (and bringing plenty of water!) is a good idea, too.</p> <h2>Do: Watch your dog’s behaviour</h2> <p>“Dogs may slow down, look in your direction, or outright refuse to move if they are feeling tired or don’t want to walk,” Dr Conrad says – and it’s important to respect this cue. Take notice of any excessive panting or unusual fatigue as well, Dr Miller adds, as these are clear signs to end the walk.</p> <p>If you sense that your dog is peeing more than usual, you should contact your vet – this could be a sign of illness.</p> <h2>Do: Let your dog sniff around</h2> <p>“Behaviourally, there’s nothing wrong with your dog frequently stopping to sniff their environment, and it can be good enrichment for them,” Dr Miller explains. “Sniffing is one of the main ways your dog experiences their environment, and there can be lots to take in on a walk, even in a familiar area.”</p> <h2>Do: Use positive reinforcement</h2> <p>Avoid reprimanding your dog or using other forms of punishment, even if it seems mild, like pulling on their collar, Dr Miller says. Research, such as one 2020 study, has shown that aversive-based training can cause stress and confusion in dogs, and this can lead to poor behaviour – possibly only because they don’t understand.</p> <p>“Positive reinforcement is proven to be effective,” Dr Miller says. “It promotes a focus on teaching dogs what we want them to do, such as having good manners, rather than focusing on behaviours we deem undesired.”</p> <p>You can use treats to reward your dog when they stay politely at your side, when they observe other dogs calmly instead of charging after them, and when they return their attention to you after something distracts them.</p> <h2>Don’t: Use retractable leashes</h2> <p>Retractable leashes allow too much freedom to explore in places that may be dangerous, Dr Conrad says – and they can make it difficult to keep control of your dog. Some larger breeds of dogs may even be able to break them, and they’re known for causing skin burns, Dr Karwacki adds.</p> <p>Here, it’s also important to note the findings of an April 2023 sports medicine study at Johns Hopkins University. A team of doctors analysed 20 years’ worth of national data and reported that on average, around 21,000 people per year seek treatment for injuries related to walking their pups on leashes. The data suggests that the majority of these injuries occur in individuals between age 40 and 64, and the most common reported injuries are finger fractures, traumatic brain injury, and shoulder sprains and strain.</p> <p>That’s one more reason to choose a stable leash (not a retractable one), pay attention to your walk (don’t lose your focus by looking at your phone or getting otherwise distracted), and be mindful of the size of dog you’ll be able to manage for the coming years when you’re looking to bring a new canine companion into your life.</p> <h2>Don’t: Let them off the leash</h2> <p>Unless you’re in a dog park, “it is essential to always keep your dog on a leash when out on a walk,” even if they’re well-behaved and trained, Dr Miller says. “You may encounter local wildlife and other people or dogs that could react negatively toward an off-leash dog or could distract your dog.”</p> <p>Dr Miller recommends using a no-pull harness that’s well-fitted (meaning it doesn’t restrict your dog’s range of motion) to encourage good behaviour and limit accidental negative reinforcement, like pulling on their collar. “If your dog gets excited and pulls during the walk, simply stop walking and reward them when they are exhibiting the desired behaviour of a loose leash,” she explains. “Continue to reward while walking when your dog is at your side and not pulling. Patience and consistency are important for reinforcing good manners.”</p> <h2>Don’t: Approach other dogs without permission</h2> <p>“Some dogs are reactive or nervous around other dogs, and having a strange dog come up to them can be intimidating and scary,” Dr Conrad says.</p> <p>Plus, not every person will be comfortable with you interacting with their pet, so be sure to over-communicate and seek permission, adds Dr Miller. (Also, stay fully focused – on-leash greetings can cause leashes to tangle up, presenting safety risks for both the dogs and the walkers.)</p> <h2>Don’t: Walk right after they eat</h2> <p>Avoid going on a long walk with your dog if it’s within an hour of them eating a large meal, Dr Miller says. This reduces the risk of stomach bloat, which can be harmful to your dog. (Besides, is there any feeling more satisfying than putting their breakfast bowl in front of them right after your morning walk? We think not.)</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/pets/vets-share-their-5-best-tips-for-safer-dog-walks-and-5-things-never-to-do" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

7 hot things to do this winter

<p>The best thing about winter in Australia is that in most parts of the country the weather doesn’t stop you from spending time outside. While swims at the beach might be out, there are still many things you can do out in the fresh winter air. We’ve rounded up some of our favourites.</p> <p><strong>1. Christmas in July picnic</strong><br />While people may think picnics are a summer-only activity, when it’s a sunny winter's day there is nowhere better to be than outdoors. As long as you suitably rug up, a picnic in your local park with family and friends is the perfect way to spend the day. With July coming up why don’t you get your family and or friends together and throw a Christmas in July party. It’s even an appropriate time get out the Christmas jumpers – something we cannot do on December 25th in this country.</p> <p><strong>2. A trip to the zoo</strong><br />Visiting the zoo is a great day out for all, young and old. Many zoos across the country put on special shows and activities during the school holidays (think June/July), so this is a great time to think about taking younger family members or the grandkids.</p> <p><strong>3. Wine and cheese tasting</strong><br />Whether you want to head out to some wineries for the day or have your own wine and cheese tasting soiree at home, winter is the perfect time to kick back with a lovely glass of red and a platter of cheeses. While Australia has many amazing wineries that everyone should try, we also love the idea of holding a wine tasting party. You can assign one type of wine to each of your guests and even theme the day (wines from one country or each person brings a wine from where they grew up) to make it more fun.</p> <p><strong>4. Walk in a national park</strong><br />We are so blessed with beautiful national parks in Australia, and many of them have lots of walking trails ranging from easy to more strenuous. While rainy, snowy or extremely windy days won’t be ideal for heading out for a walk, the crisp winter air combined with the sun offers the perfect conditions for a long walk. Just don’t forget a raincoat, some water and your mobile phone in case you need them.</p> <p><strong>5. A day trip to a remote pub</strong><br />Life is all about experiences and they say that those who mix things up, are generally happier people. So quick, get out of town for the day. Research small towns nearby and look for a lovely pub to go for a nice lunch at. You might even want to make a special playlist of old songs to make the car journey extra fun.</p> <p><strong>6. Have a bake off with your friends</strong><br />It is winter, so there are bound to be some rainy or snowy days. On these days when you’re restricted to indoor activities, why not invite the grandkids, family or friends over and have a mini bake-off. Competition aside, at the end of the bake-off you’ll have some warm treats to enjoy with a nice cuppa.</p> <p><strong>7. Start a winter book club</strong><br />There’s no better time to start a book club than during winter. Not only is winter the perfect time to curl up on the couch with a blanket and catch up on reading, it is also a time when you’ll be more inclined to spend time indoors by the fire or heater. Why not turn your extra time spent reading into a book club? It gives you an excuse to catch up and spend hours on end chatting with friends – even if the conversation veers away from the book.</p> <p><em>Images: Getty</em></p>

"I started walking the long way": many young women first experience street harassment in their school uniforms

<p>Can you remember the first time you were harassed in a public space? What comes to mind? Can you remember how old you were, or what you were doing? Perhaps this is not something you have personally experienced, although we know <a href="https://australiainstitute.org.au/report/everyday-sexism/">87% of young Australian women</a> have been harassed in public.</p> <p>We spoke to 47 adult women and LGBTQ+ people in <a href="https://www.streetharassmentjustice.com/">our recent study</a> on street-based and public harassment about their earliest memories of feeling sexualised, uncomfortable or unsafe on the street. Many mentioned they first experienced street harassment in their school uniforms. We heard variations of the phrase “it happened when I was in my school uniform” repeatedly from participants.</p> <p>For many, <a href="https://theconversation.com/whistling-and-staring-at-women-in-the-street-is-harassment-and-its-got-to-stop-38721">street harassment</a> began or became more frequent when they started wearing a high school uniform. Some participants, however, reflected on experiences from when they were even younger, wearing a primary school uniform. </p> <p>Studies from the United Kingdom have shown <a href="https://plan-uk.org/street-harassment/its-not-ok">35% of girls</a> wearing school uniforms have been sexually harassed in public spaces. Despite the importance of schools in the daily lives of young people, and the high rates of street harassment they experience, there’s been surprisingly little attention paid to the harassment of young people in school uniform. </p> <p>Findings from our <a href="https://www.tandfonline.com/doi/full/10.1080/09540253.2023.2193206">new research</a> show school-related harassment is a serious issue that has largely flown under the radar in Australia.</p> <h2>It happens beyond the school gates</h2> <p>We know young people experience <a href="https://researchdirect.westernsydney.edu.au/islandora/object/uws:55181/">sexual</a>, <a href="https://www.glsen.org/sites/default/files/2019-10/GLSEN%202015%20National%20School%20Climate%20Survey%20%28NSCS%29%20-%20Executive%20Summary.pdf">homophobic and transphobic</a>harassment from their peers and even teachers while they’re at school. </p> <p>But participants also told us about harassment occurring outside their school grounds. This was perpetrated by strangers (usually individual adult men, or groups of adult men), while they were in uniform and, therefore, clearly identifiable as school children. </p> <p>This took many forms, ranging from catcalling, staring or leering, wolf-whistling, and being followed by men in cars while walking to school, through to public masturbation and men rubbing themselves against victim-survivors (usually while travelling to school on public transport), sexual assault and rape. </p> <p>As one interviewee told us, "walking from high school to home […] that’s where most of the harassment I’ve experienced happened […] As soon as I stopped wearing a school uniform it happened less. So that’s disgusting for a lot of reasons."</p> <p>As another interviewee shared, these experiences were really scary not just because of what was happening at that moment but because the perpetrator “knows which school you go to” because of the uniform worn.</p> <h2>The ‘sexy schoolgirl’</h2> <p>Why is it that young people – and particularly young women and girls – are so routinely harassed in school uniform? We found harassment of schoolgirls was seen as being culturally sanctioned through the “sexy schoolgirl” trope. </p> <p>As one interviewee noted, "when you go on Google images and search for ‘school boy’ it will come up with a five-year-old boy but then ‘school girl’ it will come up with the sexy school girl costume."</p> <p>Participants discussed being targeted because they were viewed as vulnerable and (paradoxically) as both sexually innocent and sexualised, "that was part of the allure for them [the perpetrators], the innocence of a schoolgirl, a fearful schoolgirl in that situation, was like hot to them, they were really getting off on it."</p> <p>Another interviewee told us, "I went from being an innocent child to a child that felt uncomfortable and didn’t know why I was sexualised – and I didn’t understand it because I didn’t understand what sex really was."</p> <p>Because they were so young, many participants often lacked a framework or language to understand their experiences. For many, these experiences were also so routine they simply formed part of the background hum of everyday life. </p> <p>It was often not until years after these formative experiences that participants were able to articulate them as sexual harm and reflect on the impacts. </p> <h2>Trying to avoid harassment</h2> <p>Across our interviews, many participants discussed changing the way they presented themselves or changing the routes they took to school. They often focused on changing their own behaviour and <a href="https://policy.bristoluniversitypress.co.uk/the-right-amount-of-panic">made their lives smaller</a> in an attempt to avoid further harassment. </p> <p>For example, "I started walking the long way. I started just going through the main roads, avoiding the back streets, even though it was a longer walk to be extra safe."</p> <p>In the longer-term, participants commonly described feeling unsafe, hyper-vigilant, and distrustful of men in public spaces. </p> <h2>‘What if there’s a paedophile on the tram?’: school responses</h2> <p>Unfortunately, the view that victim-survivors are responsible for their own harassment was often reinforced by schools if harassment was reported. </p> <p>Numerous participants told us how they were reminded of school uniform policies (such as mandated length of skirts and dresses) when they went to teachers for help. </p> <p>One participant recounted an experience where her teacher asked, "Why would you wear your skirt like this [short]? Whose attention are you trying to get? […] what if there’s a paedophile when you’re on the tram home from school […] thinking ‘this is the best day of [my] life’."</p> <p>Others did not seek help from their teachers because of this focus on students’ appearance at school – they felt they would simply be blamed for what happened.</p> <p>These types of responses teach young people to think street harassment and other forms of gendered violence are their fault. It also tells them their bodies are sites of risk that need to be managed and contained to avoid harassment.</p> <h2>School uniform harassment is not ‘normal’</h2> <p>While schools and school-related contexts were often sites of harm for our participants, schools nonetheless have a vitally important role to play here. Harassment in school uniform should not be seen as a “normal” part of growing up. </p> <p>There is an urgent need to provide young people with a framework to understand their experiences.</p> <p>Educational efforts must challenge the idea that harassment must simply be endured. Instead, schools should help young people understand harassment as a form of violence, and offer safe and supportive spaces to talk with peers and adults about their experiences. This should be incorporated into existing sex and relationships education <a href="https://www.bodysafetyaustralia.com.au/">in an age-appropriate way</a>.</p> <p>Importantly, responses to harassment should never blame or implicate young people themselves. It’s time for outdated practices such as measuring school uniform length to be relegated to the past where they belong. </p> <p>In the words of one participant, “the length of my skirt is not influencing how much I learn”.</p> <p><strong><em>If this article has raised issues for you, or if you’re concerned about someone you know, call <a href="https://kidshelpline.com.au/">Kids Helpline</a> on 1800 55 1800 or <a href="https://www.1800respect.org.au/">1800RESPECT</a> on 1800 737 732.</em></strong></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/i-started-walking-the-long-way-many-young-women-first-experience-street-harassment-in-their-school-uniforms-202718" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Take a walk on the wild side with the Wildlife Photographer of the Year awards

<p>The People’s Choice Award winners of the 2022 Wildlife Photographer of the Year awards have been revealed, featuring stunning images of some of the world’s most majestic creatures. </p> <p>Competition for the coveted People’s Choice Award was fierce, with over 39,000 images submitted for consideration. 25 pictures were shortlisted from there, and a staggering 60,466 votes were received to crown the winner: German photographer Sascha Fonseca. </p> <p>Sascha’s image, titled “World of the snow leopard”, presents a snow leopard at sunset in Ladakh in northern India, with a breathtaking snow-covered mountain range backdrop. </p> <p>“Thick snow blankets the ground, but the big cat’s dense coat and furry footpads keep it warm,” the image was captioned. “Sascha captured this image during a three-year bait-free camera-trap project high up in the Indian Himalayas. He has always been fascinated by snow leopards, not only because of their incredible stealth but also because of their remote environment, making them one of the most difficult large cats to photograph in the wild.”</p> <p>The winning images, selected for their “artistic composition, technical innovation, and truthful interpretation of the natural world”, boast not only a winner, but four other highly commended finalists as well. </p> <p>"This year’s record number of votes illustrates how wildlife photography can engage and inspire audiences with the wonder of nature,” said Director of the Natural History Museum Douglas Gurr.</p> <p>The other finalist feature a leopard with some unexpected cargo titled “Holding on” by Igor Altuna, a moment of “Fox affection” in the snow by Brittany Crossman, a polar bear basking in the sun “Among the flowers” by Martin Gregus, and a magnificent “Portrait of Olobor” the lion by Maasai Mara. </p> <p>The Wildlife Photographer of the Year competition, produced by the Natural History Museum, provides amateur and professional photographers from around the world with a global platform for their work. 2022 marked the 58th year of competition, and the 59th is currently being judged, with the 2023 winners to be announced in October. </p> <p><em>All image credits: Wildlife Photographer of the Year awards</em></p>

Top tips for walking your way to good health

<p>Walking is a great way to stay healthy but many people need to take those steps at a brisker pace. Here’s how to step up your routine.</p> <p>Tying those shoelaces on for a brisk walk around your local lake or along the beach is a great way to stay active. Whether it’s a morning walk along the beach or an afternoon hike along a nature trail, you can exercise for free in some of the most beautiful locations in the world. No wonder walking is so popular! Seventy-seven per cent of Aussies love walking as a form of physical activity, according to over 50s insurer <a href="http://www.apia.com.au/" target="_blank" rel="noopener">Apia</a>.</p> <p>“It’s not surprising that walking is so popular with older Aussies, given it is low impact, easy on the body, requires minimal equipment and can be done on your own or with friends anytime of the day and at your own pace,” <a href="http://www.apia.com.au/" target="_blank" rel="noopener">Apia</a>’s David Skapinker says.</p> <p>“As we get older it’s important to keep connected with people around you and fitness groups, cycling and walking meet-ups are a great way for people to stay active and socialise at the same time.”</p> <p>Free, low impact and you can do it wherever and whenever you want, who wouldn’t love walking? While an evening stroll around your block or down by the park is a relaxing way to unwind, stretch the muscles and get some fresh air, it’s not ideal for exercise. For that, you need to step up the pace. Here’s a few tips on how to do just that.</p> <p><strong>Mix it up</strong></p> <p>What makes walking great is the fact that you can start at whatever point that feels most comfortable for you, and grow from there. One of the most effective ways of increasing your fitness is with interval training which involves alternating your sessions of ‘constant speed’ with several short bursts of intense walking. After about one or two minutes of walking really fast, go back to a slower pace to catch your breath. Continue to do this over time by increasing your short bursts of intense effort into longer periods, and you’ll soon notice the difference.</p> <p><strong>Try an early morning walk</strong></p> <p>Getting motivated to exercise can always be difficult but if you get it over and done with first thing in the morning, it’s out of the way for the rest of the day. And, if you’re looking to trim a few extra kilos around the midsection, it’s the best time to lose weight. Walking before breakfast means your body has nothing to fuel itself with apart from stored fat, which means you’ll burn off excess kilos in no time. Plus, it’s a great way to start the day. You’ll feel good, energised and ready to tackle any of the day’s demands with renewed vigour.</p> <p><strong>Explore different trails</strong></p> <p>Mix up your walking routes to challenge your body with different surfaces. Stick to the footpath one morning and then try slipping off your sneakers, and walking along the beach another morning. If you live in a hilly area, even better. Try an uphill walk followed by a gentle descent to catch your breath. Your body adapts quickly to new challenges, so you always have to stay one step ahead of yourself. Remember, don’t go too hard too quickly. Ease yourself into new routes and new challenges rather than trying to push yourself too quickly since you may injure yourself. Be careful and take it one step at a time.</p> <p><strong>Find a buddy</strong></p> <p>The best way to stay motivated and to chart your progress in getting faster is with a walking buddy! Find a friend who has the same goal as you – to get fitter by changing their walking patterns. This will not only keep you motivated but you can push each other to go a step better than you did the other day. Soon, you’ll both be feeling fitter and walking faster, and can celebrate your achievement together.</p> <p><em>Image: Getty</em></p>

Pesticide exposure makes it harder for bees to walk in a straight line

<p>Bees, long despised for stinging humans and pets, but loved by horticulturalists for their life giving goodness, are under attack like never before.</p> <p>In June research identified a dangerous variant of the deformed wing virus is <a href="https://www.sciencedaily.com/releases/2022/06/220601111805.htm#:~:text=Summary%3A,and%20the%20animals%20to%20die." target="_blank" rel="noopener">on the rise worldwide</a>. The virus infects honeybees, causing their wings to atrophy and the animals to die. </p> <p>Also that month the varroa mite, a major honeybee parasite, was discovered in biosecurity surveillance hives at the Port of Newcastle.</p> <p>Now new research has identified what happens to bees when they are subject to insecticides.</p> <p>Have you ever struggled to walk in a straight line after having one too many? Well, it seems that honeybees are having similar issues but after getting a dose of insecticides.</p> <p>“Here we show that commonly used insecticides like sulfoxaflor (kills aphids and lygus) and the neonicotinoid imidacloprid (pesticide that protects seeds of field crops) can profoundly impair the visually guided behaviour of honeybees,” <a href="https://www.scimex.org/newsfeed/bees-struggle-to-fly-in-a-straight-line-if-theyve-been-exposed-to-pesticides" target="_blank" rel="noopener">said lead author of a new study</a>, Dr Rachel H Parkinson from the University of Oxford.</p> <p>“Our results are reason for concern because the ability of bees to respond appropriately to visual information is crucial for their flight and navigation, and thus their survival.”</p> <div class="newsletter-box"> <div id="wpcf7-f6-p202420-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> </div> </div> <p>Insects have an innate ‘optomotor response’, which lets them orient themselves back onto a straight trajectory if they steer off-course while walking or flying.</p> <p>The research, published in <a href="https://www.frontiersin.org/articles/10.3389/finsc.2022.936826/full" target="_blank" rel="noopener"><em>Frontiers in Insect Science</em></a><em>,</em> challenged this optomotor response of walking honeybees by putting them in front of video screens of vertical lines which tricked them into thinking they’d moved off course.</p> <p>The vertical bars would move from left to right, or right to left which ‘tricks’ the bee into thinking it’s been blown off-course and needs to perform a corrective turn.</p> <p>The team of researchers looked at four groups of between 20-30 bees. The control had access to normal sugar water to drink, while the other three had different forms of insecticides added. One group had 50 parts per billion of imidacloprid, another had 50 parts per billion sulfoxaflor, and the last had 25 parts per billion of imidacloprid and 25 parts per billion of sulfoxaflor together.</p> <p>Unfortunately, the bees which had been exposed to the insecticide performed worse as they turned to get back on track. Bees exposed to pesticides seemed to have shallower turns and sometimes only turned one way. The asymmetry between left and right turns for example was 2.4 times greater for those bees exposed to pesticides.</p> <p>After this experiment, the researchers then had a look at the bee brains to look at the damage. Using molecular techniques, the team found that pesticide-exposed bees tended to have an elevated proportion of dead cells in parts of the brain’s optic lobes, which is important for processing visual input.</p> <p>Key genes for detoxification were also dysregulated after exposure. However these brain changes were relatively weak and highly variable across bees, and unlikely to be the sole explanation for the strong visual issues in the original experiment.</p> <p>“Neonicotinoid and sulfoximine insecticides activate neurons in the insect brain and are not always recycled fast enough to prevent toxicity,” said Parkinson.</p> <p>This research comes on the heels of a slew of other research in recent years suggesting that pesticides <a href="https://cosmosmagazine.com/nature/pesticides-impair-baby-bee-brain-development/">impair baby bee brain development,</a> or it can make <a href="https://cosmosmagazine.com/nature/neonicotinoids-make-bees-antisocial-and-lazy/">them antisocial and lazy</a>, and many scientists <a href="https://cosmosmagazine.com/earth/sustainability/scientists-call-for-urgent-action-on-bee-killing-insecticides/">are asking for them to be banned</a>.</p> <p><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=202420&amp;title=Pesticide+exposure+makes+it+harder+for+bees+to+walk+in+a+straight+line" width="1" height="1" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/earth/pesticide-exposure-bees-walk-straight-line/" target="_blank" rel="noopener">This article</a> was originally published on <a href="https://cosmosmagazine.com" target="_blank" rel="noopener">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/jacinta-bowler" target="_blank" rel="noopener">Jacinta Bowler</a>.

Walk well. Age well.

<p>Despite the fact that everyone knows that exercise is beneficial, hard scientific evidence of its benefits for the more mature have been surprisingly limited. Until now that is. Findings recently released from the study, Lifestyle Interventions and Independence for Elders (or LIFE), suggest that regular exercise, including walking, significantly reduces the chance that a frail older person will become physically disabled. Ever needed more of push to ensure you undertake frequent physical activity?</p> <p>Published in the Journal of the American Medical Association, Dr Marco Pahor – the director of the Institute on Aging at the University of Florida and the lead author of the study – said, “For the first time, we have directly shown that exercise can effectively lessen or prevent the development of physical disability in a population of extremely vulnerable older people.”</p> <p>So, you’re probably thinking you’ve heard something along these lines before: “There’s a strong connection between physical activity in advanced age and a longer, healthier life.” While there has been much research to this effect, such studies haven’t gone as far to prove that exercise improves a mature person’s health, only that healthy people of such an age exercise.</p> <p>The LIFE study, which took place over two-and-a-half years, is particularly interesting because rather than selecting relatively robust volunteers to take part who could easily exercise; it opted for volunteers who were sedentary and infirm, and on the cusp of frailty. All in all, 1635 people were selected aged 70 to 89.</p> <p>For the study there were two groups, and education or exercise category. Those in the education group visited a research centre once a month to learn about nutrition, health care and other topics related to ageing. On the contrary, the exercise group started a program of walking as well as light, lower-body weight training with ankle weights; going to the research centre to receive some information about ageing but also for twice-weekly supervised group walks on a track. The walks grew progressively longer over time. In addition to this, they were also asked to complete three or four more exercise sessions in their own time, aiming for 150 minutes of walking and three 10-minute weight-training sessions each week.</p> <p>While the results were good all round, with the exercising volunteers 18 per cent less likely to have experienced any physical disability during the experiment, there was little difference between the number of people who became disabled in the two groups. For instance, 35 per cent of those in the education group had a period of physical disability during the study versus 30 per cent in the exercise group. While at first glance those stats might seem disappointing, it is interesting to learn that the study data shows that in many cases the participants in the education group began to exercise, despite not being directed to, which may have affected the outcome.</p> <p>The important thing to take from this study is how important it is to keep active in order to prevent physical disability as you age. The study highlights the necessity for regular exercise, including walking, in significantly reducing the chance that a frail older person will become physically disabled. And as with most things, it’s best to consult medical advice before starting any sort of physical activity.</p> <p>While the scientists who worked on the study continue to examine their results for further analysis, we leave you with this quote from Mildred Johnston, an 82-year-old retired office worker who volunteered for the LIFE study. She has kept up her weekly walks with two of the other volunteers she met during the study.</p> <p>“Exercising has changed my whole aspect of what ageing means,” she revealed. “It’s not about how much help you need from other people now. It’s more about what I can do for myself.” The walking coupled with the conversation during her walking sessions, “really keeps you engaged with life,” she says. </p> <p><em>Image: Getty</em></p>

"They are not dogs": Father slammed for walking his five kids on a leash

<p>A father-of-five has been slammed online after sharing a video of his five-year-old quintuplets being walked around on a leash. </p> <p>Jordan Driskell, a 31-year-old dad from Kentucky USA, uploaded a video to Instagram which showed him walking with his five young kids: Zoey, Dakota, Hollyn, Asher and Gavin. </p> <p>He wrote in the caption, "When people judge me for using child leashes, come walk a mile in my shoes."</p> <p>The clip showed Jordan holding on to five ropes - which were each connected to a harness that one of his kids wore - as the family all walked calmly together outside of an aquarium.</p> <p>The now-viral video quickly stirred up controversy, with many people in the comments slamming his choice, while others agreed it was an effective safety tool. </p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/Cf9-IhXgUnY/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/Cf9-IhXgUnY/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by DRIX (@drixxleman)</a></p> </div> </blockquote> <p>"I have nothing but respect for you sir," wrote one supportive viewer.</p> <p>Another added, "Better safe than sorry.

A robot dog with a virtual spinal cord can learn to walk in just one hour

<p>We’ve all seen those adorable clips of newborn giraffes or foals first learning to walk on their shaky legs, stumbling around until they finally master the movements.</p> <p>Researchers wanted to know how animals learn to walk and learn from their stumbling, so they built a four-legged, dog-sized robot to simulate it, according to a new study <a href="https://www.nature.com/articles/s42256-022-00505-4" target="_blank" rel="noreferrer noopener">reported</a> in <em>Nature Machine Intelligence</em>.</p> <p>They found that it took their robot and its virtual spinal cord just an hour to get its walking under control.</p> <p>Getting up and going quickly is essential in the animal kingdom to avoid predators, but learning how to co-ordinate leg muscles and tendons takes time.</p> <p>Initially, baby animals rely heavily on hard-wired spinal cord reflexes to co-ordinate muscle and tendon control, while motor control reflexes help them to avoid falling and hurting themselves during their first attempts.</p> <p>More precise muscle control must be practised until the nervous system adapts to the muscles and tendons, and the young are then able to keep up with the adults.</p> <p>“As engineers and roboticists, we sought the answer by building a robot that features reflexes just like an animal and learns from mistakes,” says first author Dr Felix Ruppert, a former doctoral student in the Dynamic Locomotion research group at the Max Planck Institute for Intelligent Systems (MPI-IS), Germany.</p> <p>“If an animal stumbles, is that a mistake? Not if it happens once. But if it stumbles frequently, it gives us a measure of how well the robot walks.”</p> <figure class="wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"> <div class="wp-block-embed__wrapper"> <div class="entry-content-asset"> <div class="embed-wrapper"> <div class="inner"><iframe title="Learning Plastic Matching of Robot Dynamics in Closed-loop Central Pattern Generators" src="https://www.youtube.com/embed/LPL6nvs_GEc?feature=oembed" width="500" height="281" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div> </div> </div> </div> </figure> <p><strong>Building a virtual spinal cord to learn how to walk</strong></p> <p>The researchers designed a <a href="https://cosmosmagazine.com/health/machine-learning-tool-brain-injury/" target="_blank" rel="noreferrer noopener">learning algorithm</a> to function as the robot’s spinal cord and work as what’s known as a Central Pattern Generator (CPG). In humans and animals, the CPGs are networks of neurons in the spinal cord that, without any input from the brain, produce periodic muscle contractions.</p> <p>These are important for rhythmic tasks like breathing, blinking, digestion and walking.</p> <div class="newsletter-box"> <div id="wpcf7-f6-p198628-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> </div> </div> <p>The CPG was simulated on a small and lightweight computer that controlled the motion of the robot’s legs and it was positioned on the robot where the head would be on a dog.</p> <p>The robot – which the researchers named Morti – was designed with sensors on its feet to measure information about its movement.</p> <p>Morti learnt to walk while having no prior explicit “knowledge” of its leg design, motors, or springs by continuously comparing the expected data (modelled from the virtual spinal cord) against the sensor data as it attempted to walk.</p> <p> “Our robot is practically ‘born’ knowing nothing about its leg anatomy or how they work,” Ruppert explains. “The CPG resembles a built-in automatic walking intelligence that nature provides and that we have transferred to the robot. The computer produces signals that control the legs’ motors and the robot initially walks and stumbles.</p> <p>“Data flows back from the sensors to the virtual spinal cord where sensor and CPG data are compared. If the sensor data does not match the expected data, the learning algorithm changes the walking behaviour until the robot walks well and without stumbling.”</p> <p>Sensor data from the robot’s feet are continuously compared with the expected touch-down data predicted by the robot’s CPG. If the robot stumbles, the learning algorithm changes how far the legs swing back and forth, how fast the legs swing, and how long a leg is on the ground.</p> <p>“Changing the CPG output while keeping reflexes active and monitoring the robot stumbling is a core part of the learning process,” Ruppert says.</p> <p>Within one hour, Morti can go from stumbling around like a newborn animal to walking, optimising its movement patterns faster than an animal and increasing its energy efficiency by 40%.</p> <p>“We can’t easily research the spinal cord of a living animal. But we can model one in the robot,” says co-author Dr Alexander Badri-Spröwitz, head of the Dynamic Locomotion research group.</p> <p>“We know that these CPGs exist in many animals. We know that reflexes are embedded; but how can we combine both so that animals learn movements with reflexes and CPGs?</p> <p>“This is fundamental research at the intersection between robotics and biology. The robotic model gives us answers to questions that biology alone can’t answer.”</p> <p><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=198628&amp;title=A+robot+dog+with+a+virtual+spinal+cord+can+learn+to+walk+in+just+one+hour" width="1" height="1" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/technology/robot-machine-learning-to-walk/" target="_blank" rel="noopener">This article</a> was originally published on <a href="https://cosmosmagazine.com" target="_blank" rel="noopener">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/imma-perfetto" target="_blank" rel="noopener">Imma Perfetto</a>.

"Walk the rooms": Inside the house that Johnny Cash built

<p>Johnny Cash's former home has hit the market, with the California property expected to sell for up to $1.8 million.</p> <p>Cash, who passed away in 2003 at the age of 71, shared the property with his first wife, Vivian Liberto, and the home is adorned with the relics of Johnny's love for music.</p> <p>The house features a wood-panelled recording studio, wall-mounted turn tables and a country motif living room.</p> <p>The artist reportedly built the 4,500 sq. ft. home in Casitas Springs, California, back in 1961 as an escape from his demanding lifestyle.</p> <p>Johnny and Vivian, along with their three daughters, spent six years in the homestead retreat, which was rumoured to be built to Cash's exact wishes.</p> <p>According to the listing agents of Douglas Elliman, "Johnny bought the land and built the house to his exact specifications, walking the rooms and deciding on exact placement and layout. He created a secluded sanctuary, unique to this rural small-town enclave. Longtime locals recount stories of Johnny setting up speakers on the hillside outside the house and playing concerts for the townspeople down below."</p> <p>Inside the five bedroom home, most rooms remain original to Johnny and Vivian's vision, with painted ceilings featuring a touch of glitter, an original wall-mounted turntable and intercom system, and curved brick fireplace in the family room.</p> <p>Despite a modern uplift in the his and hers suites, the property is undeniably Cash's with custom wood built-ins, exposed brick walls, natural wooden beams and a country motif living room.</p> <p>The grounds are equally mesmerizing with live oaks, verdant gardens, a sparkling swimming pool, and corrals and fields ready for horses, pigs, goats, chickens or other rural uses.</p> <p><em>Image credits: Douglas Elliman Realty</em></p>
