Dr Glenn McConell chats with Professor Irene Davis from the University of South Florida who is a top running injuries researcher and the current president of the American College of Sports Medicine. She makes the argument that we were born to run and have evolved to land on the ball of the foot during running and this reduces impact load compared with landing on the heel. Modern running shoes tend to increase the likelihood of landing on one's heel. She is a fan of minimalist shoes, which tend to result in landing on the forefoot not the heel. She also believes that neutral shoes are best rather than the commonly advised shoes that attempt to minimize pronation. In addition, she also believes that if one has stubborn injuries and have tried other rehabilitation retraining your running gait may be helpful. Not a huge fan of orthotics. I was actually blown away by the chat and very motivated by it. Really fun stuff. Twitter: @IreneSDavis 0:00. Introduction to podcast/Irene Davis 3:05. How Irene got into exercise research 6:43.

In this episode on the Restore To Explore podcast, Nick welcomes Dr. Irene Davis on the show. Irene discusses her background in biomechanics and physical therapy, as well as her interest in feet and the shift in focus towards understanding the importance of natural foot movement. She shares her epiphany moment and the change in perspective that led her to question traditional footwear paradigms. Irene highlights the challenges in changing the perception of footwear and the need for education and empowerment among runners. She emphasizes the importance of viewing the lower body as an integrated system and the role of foot muscles in overall foot health. Finally, she provides a simplified explanation of the ideal footwear, which allows the foot to function naturally. She explains that while there are now more options for natural footwear on the market, it is essential to educate individuals on what to look for in a shoe. Davis also shares her current research focus on the impact of minimal shoes on bone health, particularly the metatarsals. She encourages health professionals to explore the topic of minimal footwear and references a paper on the subject as a valuable resource. Finally, Davis and Nick discuss the future of foot health and the potential for a shift towards functional and natural footwear.Chapters00:00Introduction and Background03:01Interest in Feet and Shift in Focus10:04Epiphany Moment and Change in Perspective18:38Challenges in Changing Footwear Paradigm25:27Educating and Empowering Runners32:09Viewing the Lower Body as an Integrated System36:03Importance of Foot Muscles and Lack of Awareness41:37Changing the Perception of Feet42:53Simplified Explanation of Ideal Footwear43:36The Importance of Natural Movement and Footwear47:10Current Research and Future Directions49:48Advice for Health Professionals50:45The Future of Foot Health TFC Helpful Links: Free Training Explorer Membership Free Ebook (The Guide To Foot Freedom) Shop TFC tools and training (Use the code R2E10 to save 10%) Become A TFC Athlete TFC Pro Directory Natural Footwear Finder Fountain - Earn money while you listen to our podcast Follow us: Instagram TikTok YouTube Facebook Music: Dream Chaser - Lunareh Written By - Wiriyapa Chansuwong Performed & Produced By - Lunareh

Join us on PT Elevated as JJ Thomas and Kory Zimney talk with Doug Adams, PT, DPT, SCS, OCS, CSCS, a running gait analysis expert, researcher and friend of JJ Thomas. Adams' career started with a background heavy in research from University of Delaware, learning alongside Irene Davis, Richard Willy and Lynn Snyder-Mackler. Doug talks about his struggle with not getting the results that he wanted when he was in residency and at the beginning of his career. There was a moment where he had to realize that he needed guidance from his colleagues to grow as clinician. That pushed him to rely on a process of test-retest to get the best results. Through that learning process, he came to the conclusion that having a systematic approach that is backed by research is more important than finding the perfect systematic approach. There's more than one way to get people better. Here are some of the key takeaways from the conversation: Studies that altered how you treat runners Ability of Sagittal Kinematic Variables to Estimate Ground Reaction Forces and Joint Kinetics in Running A compilation from Google Scholar of Rich Willy's research Key Screens for Every Runner Focus on mobility and motor control Runner Readiness Assessment Unilateral Hip Bridge Endurance Test Clinical Pearl: A great drill to help your runners not overstride is marching.

25% of the bones and joints in your entire body are located in your feet and ankles. Also, you have over 200,000 nerve endings on the sole of each foot. So why are we covering up these sensory powerhouses with padding and cushioning? Walking around or even running barefoot, or with footwear designed to let the feet be feet, can improve our overall physical health in ways we never imagined. WELCOME TO THE DARIN OLIEN SHOW. On this podcast, you'll hear me, Darin Olien, "the superfood hunter," have honest conversations with the extraordinary people that inspire me. I hope that through their knowledge and unique perspectives, they'll inspire you, too. Although our ideas and approaches to life may differ, our ultimate goal is the same- to save the planet one conversation at a time. So, if you're interested in expanding your view of the world by learning new perspectives on health, nutrition, and healing the planet, this podcast is for you.  Steven Sashen dives into things feet first. In fact, it’s his company motto. Xero Shoes was built out of a need for Steven to free his feet. After picking up sprinting again following a 30 year hiatus, Steven would injure himself constantly. Every couple of weeks would bring another pulled muscle or ankle strain. When a friend suggested a barefoot run, everything changed. After his first run with a barefoot running group, Steven was awakened with a new awareness of how his feet interacted with the ground. He ran 5K on that very first go around and was shocked at how easy it felt on his body. He was even able to pinpoint a reason for why he was injuring one leg more than the other. All this knowledge was too empowering to ignore, and Xero Shoes was born. In this conversation, Steven and I get into how incredibly powerful and intuitive our feet really are. We explore the foot to brain connection and how the modern day athletic shoe is counterproductive to the way we physically interact with the ground under our feet. Steven gives us the origin story of Xero Shoes, which gives you an understanding of why I refer to him as a “Master of Movement”. So kick off your shoes, and take a listen to this one, guys! Other topics in this episode: Steven’s history with movement How to recognize  “Big Shoe” propaganda How Steven’s research background at Duke helped fuel Xero Shoes The lies we’ve been fed about our feet How watching a child run barefoot can give you better idea of how the body is supposed to work The truth about your arch The copycat nature of the athletic shoe industry Dr. Irene Davis and her contribution to barefoot running Balance and the elderly How tricking your brain can keep you young Steven and Lena’s Shark Tank experience with Mr.Wonderful Links & Resources: Steven’s Website Xero Shoes  Steven on LinkedIn Steven on Twitter Xero Shoes on Instagram Dr. Irene Davis Barefoot Running by Michael Sandler The Brain That Changes Itself: Stories of Personal Triumph From The Frontiers of Brain Science Born to Run by Christopher McDougall Watch Steven and Lena on Shark Tank Netflix’ Down To Earth’ Official Trailer Download Darin’s amazing new lifestyle app and get 3 days free at 121Tribe.com Barukas Nuts 15% discount with code “DARIN” The Darin Olien Show is produced by the team at Must Amplify. If you’re looking to give a voice to your brand, and make sure that it’s heard by the right people, head to www.mustamplify.com/darin to see what Amplify can do for you.

Podcast Notes Key Takeaways “If the feet aren’t working correctly, the injury can go all the way to the neck.” – Peter AttiaRunning shouldn’t be just a skill, it’s an activity of daily living – we run from danger  The two features most often seen with injuries are high impact (landing hard), and malalignment – most commonly the knees tracking inward towards each otherThe impact is lower when you run on the ball of your foot, which happens more naturally when running barefoot  Choose shoes that let your feet do what they were supposed to doWalking in minimalist shoes is as effective as a foot strengthening programEven kids should wear minimalist shoes as prevention for many of the gait issues and chronic joint pains developed in adulthoodRead the full notes @ podcastnotes.orgIrene Davis is the founding Director of the Spaulding National Running Center at the Harvard Medical School.

Happy Biomechanics Day! With Irene Davis & Cara Lewis

Today’s interview is with Max Paquette, who specializes in biomechanics and is considered an expert in running shoes. We move back to a more scientific look at running with this episode, because I know many many runners have an interest in how their biomechanics influences their racing and running. His interest started off in high school doing a project where he video taped runners. He quickly admits he knew nothing, and thinks that even with the more he studies the less he thinks we know about what makes us have good running form. We discuss the reality of the amount of information that is out there and how best to separate what is good and bad information. Max provides the names of several resources he thinks are the best to consult based on their research. Our discussion today covers popular and controversial topics such as over-pronation, cadence, forefoot vs mid-foot vs heel striking and the impact on running injuries. We then go on to discuss whether running is bad for your knees and causes arthritis. We go over the research on whether the shoe type really matters in injury prevention. We then spend some time on the last myth of biomechanics - whether strength training really make a difference? Lastly we discuss the importance of tools for runners. Ultimately the best tool for runners is to learn to run by feel not by Garmin. Having a better perception of what your body is feeling is far more important. Today’s Guest Dr. Max Paquette has a PhD in biomechanics and is an Assistant Professor at the University of Memphis.  His focus is on the effects of exercise interventions and gait modifications on joint mechanics, function and quality of life in aging and knee osteoarthritis populations. He is also interested in the effects of different footwear, fatigue, foot strike patterns and training interventions in runners on injury and performance.  He resides in Memphis with his wife Lauren and two dogs. What you will learn about: How he thinks Alex Hutchinson is one of the experts we should pay attention to, because he does great research into his topics and is a great writer who disseminates . Others he believes do a great job of disseminating complicated information are Tom Goom (Twitter @tomgoom), Rich Willy (twitter @rwilly2003), JF Esculier at University of British Columbia (Twitter @JFEsculier), and Irene Davis (@IreneSDavis) We discuss how over-pronation used to be thought of as the cause of lower leg injuries, but how his research has found that it doesn’t drive injuries. How quickly the vertical ground reaction force is transferred (impact of the ground into your foot) is also not linked to injury. What is more predictive is how quickly you add load vs more gradual increases. We talk about how we rarely study those rare specimens that don’t get hurt, we study the hurt runners. We need to shift the focus to why some don’t get hurt. The lower limbs are the most likely to first be injured, then higher up the chain. The external loads are applied to the foot first, then up the chain. But if those parts of the body are conditioned to adapt to that force, the risk of injury goes down. Up the chain, especially in females, there are other nutritional and hormonal issues that impact bone health, and folks like Trent Stellingwerff and Adam Tenford (Harvard) have done more work on female athletes and bone issues. Chris Napier (@runnerphysio) is doing some interesting work on over-striding/step length, cadence and step length/reach (how far ahead of your pelvis) impact injury risk. It is physically impossible to precisely land under your hips, you are always hitting a bit ahead which is important to store elastic energy. But it isn’t clear how much is too much. There are different permutation on how you run that impact the loads and it is not simple to determine which one is most critical. Rich Willy and John Wilson’s gait retraining studies have shown that increasing cadence (steps per minute) seems to work well at lessening injury if you find you are over-reaching and if you are suffering from lower leg issues. But if you are not getting injured perhaps you are not really overstriding.  Osteoarthritic issues: Lack of exercise is far worse than using the joints. The evidence is becoming really strong that running is not bad for your knees, and may actually be helpful with preventing the onset of the disease. Recent research is showing that even with those that have OA, some running may well be better than being sedentary. (did he send you info for the show notes?) Footwear for runners: The main conclusion of his study in 2009-2013, which was males only and highly trained runners, was the only time that the shoe mattered was in heal strikers that ran barefoot or in minimalist shoes. Forefoot strikers it just didn’t matter. But we didn’t study long term effects. Irene Davis then studied untrained runners of both sexes and concluded that it mattered more in the types of shoes people were used to running in. So if they were used to running barefoot or in minimalist shoes there was not an issue. If you are going to change shoes, you should have a good reason to change and have tried other methods first to reduce injury, not just because there is some cool new shoe. Proper training and progression come first. Ultimately it all seems to come out even in the end, no shoe ultimately matters. Benno Nigg, Univ of Calgary, has found in his research that shoes and inserts don’t matter. Rotating shoes (any shoes), surfaces and routes may be much more critical to injury prevention. Coaching his wife Lauren really showed the value of strength training in injury prevention. Learn to listen to how you feel not vs what your watch or heart rate monitor is telling you. If you body is saying it is too hard, then for that day it is too hard. Tomorrow it may not be as hard, each day is different. Inspirational Quotes: The more we learn the less we find we really know about running injuries. In the end it all comes down to the strength of your body. If you are strong you can undertake more training.

Irene Davis, PhD, PT, FAPTA of Harvard University is our guest for this Mountain Land Running Medicine Podcast. Dr. Davis is a Professor in the Department of Physical Medicine and Rehabilitation and the founding Director of the Spaulding National Running Center. She has pioneered the area of retraining faulty gait patterns in both walking and running, and an advocate for the importance of foot health in runners.

We often speak of “proper running” and when we invoke this term, its often met with controversy. Its time to put the quibbling to bed. Our guest, Dr Irene Davis is one the most respected authorities on the subject of running biomechanics. She does not pull her punches when it comes to running and what she refers to as “Running Evolution”. For many, this interview will be hard hitting and will at minimum, cause the heel strikers to pause and reflect not only on the way they approach their running but on running shoe selection.  Who is Irene Davis? Dr. Irene Davis is the founding Director of the Spaulding National Running Center, Department of Physical Medicine and Rehabilitation, Harvard Medical School. She received her Bachelors degree in Exercise Science from the University of Massachusetts, and in Physical Therapy from the University of Florida. She earned her Masters degree in Biomechanics from the University of Virginia, and her PhD in Biomechanics from Pennsylvania State University. She is a Professor Emeritus in Physical Therapy at the University of Delaware where she served on the faculty for over 20 years.  Dr. Davis' research has focused on the relationship between lower extremity structure, mechanics and injury. She is interested in the mechanics of barefoot running and its effect on injury rates, and is a barefoot runner herself. Along with gait analysis, her research encompasses dynamic imaging and modeling. Heres a brief overview of what will be discussed: Barefoot running, should you do it, where and how often?Running shoe design, whats the right shoe to wear?Is it okay to heel strike?What is the preferred approach, heel, mid or forefoot stride?

Most of us have been there. You’re in the thick of training just a few weeks away from your big goal race, and then one morning you step out of bed to feel a new pain - a pain far worse than the everyday soreness you know too well. *insert expletive* So what does the doctor prescribe? You guessed it. Time off. These two words are pretty much the last thing we runners want to hear after months and months of hard work, and the thought of scrapping all that work and starting over after your goal race has come and gone can be demoralizing. But it doesn’t have to be that way. Enter Dr. Christopher Segler of Doc On The Run, a San Francisco-based practice that specializes in podiatry and running injuries. An accomplished marathoner and Ironman triathlete, Chris knows full well how frustrating injuries can be, which is why he’s devoted his life’s work to getting sidelined runners healthy and back to the grind as fast as possible. So what’s the first step to a speedy recovery? According to Chris, don’t take time off. You read that right. Despite those conventional protocols to which we’re accustomed (“six weeks off” ring any bells?), Chris maintains time off is not only unnecessary, but it’s also counterproductive to recovering from most injuries. In this episode of Run to the Top, Chris will dispel the myths surrounding injury and discuss better alternatives to time off - methods that help you bounce back not only stronger than before but also equipped with the knowledge crucial to preventing future injury. Here are some of the topics we’ll discuss today: A little about Chris and Doc On The Run The most common causes of injury among runners Stresses and lifestyle habits that contribute to injury Chris’ thoughts on minimalist and maximalist shoes Why inactivity is counterproductive to recovery When time off is actually warranted How to remain active while recovering Questions Chris is asked: 3:10 Tell us about yourself as an athlete as well as Doc On The Run. 6:08 What have you found to be the most common cause of injury? 7:27 What are the typical causes of plantar fasciitis and  metatarsal stress fractures? 11:14 How would you advise people maximize their 'stress threshold' without exceeding it? 13:20 How familiar are you with Irene Davis and her research? 14:29 Do you think that footwear causes injuries? 17:07 Do you advocate minimalist shoes? 22:34 When should a runner avoid using minimalist shoes? 24:48 What do you mean when you say that runners have an unfair advantage when it comes to recovering from injuries? 29:46 Why is inactivity the last thing a runner needs when recovering from an injury? 36:55 Why does conventional medicine have such difficulty with treating runners? 37:42 What should runners actually do to facilitate recovery for different types of injuries? 44:58 How should an injured runner know when it's time to swap out running for a lower impact activity to aid recovery? 48:39 How can runners determine which cross training activity best suits their injury? 49:57 Will anti-inflammatories inhibit recovery? 56:26 The Final Kick Round Quotes by Chris: “That’s the way I’ve really shaped my practice is to help runners achieve their goal - not just make their pain go away.” “People say running causes running injuries, and that’s just not true.” “A news guy was interviewing a highway patrolman, and he was talking about snow - it had just started snowing in Lake Tahoe. And then while they were standing there talking about this, there was actually an accident right behind them….And so the interviewer said to the highway patrolman, ‘Well isn’t it true that snow causes accidents?’ And the highway patrolman looked at him like he was an idiot, and he said, ‘No, driving too fast for conditions causes accidents.’” “I believe you only have so much stress that your body can take, and if it’s too much then something breaks.” “The overwhelming majority of children actually run as forefoot or midfoot strikers. 85% of adults run as rearfoot strikers. 85% of adults who run as rearfoot strikers have also all been wearing some sort of shoe that has an elevated heel usually somewhere roughly in the vicinity of 12mm for pretty much their entire lives.” “I believe that most runners who have been habitually active - that cycle of tissue damage and tissue repair effectively trains your immune system and your body to heal injuries faster.” “Most runners don’t feel good when they don’t run, and it’s not because they’re exercise addicts. It’s because their physiology is different.” “I think it sets up a whole chain of recurring injuries when you stop running.” “The doctors look at it and they say if you want this one thing - this one injured thing to get better - you have to pay for it by this whole protocol that we use in America as the standard treatment. And they don’t even mention that you’re going to have this enormous risk of recurring injuries that may or may not ever go away.”   Take a Listen on Your Next Run Want more awesome interviews and advice?

Since Christopher McDougall popularized the practice in his 2009 publication of Born to Run, more and more runners have been opting for minimalist shoes or, ditching the foam altogether, barefoot running. Followers of the barefoot movement maintain the practice both significantly reduces injury and improves running performance. But is there real, scientific proof to back these claims? According to Dr. Irene Davis, the answer is a resounding yes. Irene is one of sport’s leading experts on running biomechanics and injury as well as the most credible minimalist shoe and barefoot running advocate in the world. A professor in the Department of Physical Medicine and Rehabilitation at Harvard Medical School, Irene’s research revolves primarily around the relationship between lower extremity mechanics and injury. She’s devoted the last decade to developing protocols to alter runners’ gait patterns and thereby reduce those mechanics known to cause injury - mechanics, as Irene has learned, often caused by footwear. Listen in as Irene explains how the evolution of footwear has ultimately come to defy our own. Here are some of the topics we’ll discuss today: Irene’s background and running biomechanics research How Irene became a barefoot and minimalist shoe advocate Why injury rates are so high among runners Differences in biomechanics between traditional shoes, minimalist, and barefoot How to modify running gait to reduce risk for injury and improve performance How to strengthen your feet How to transition to minimalist shoes/barefoot running if interested Minimalist shoe brands Questions Irene is asked: 4:30 What research are you involved in? 4:54 How did you get involved in biomechanics research? 5:36 Were you initially working with the general public or professional athletes? 6:22 Given your prior background, when and why did you become a barefoot running advocate? 9:12 Why do you think so many runners get injured every year? 10:44 Why do you believe supportive footwear is causing injuries? 14:03 Are these shoes encouraging heel-striking? 16:29 Is it correct to assume that strengthening your intrinsic and extrinsic muscles will correct issues? 18:46 Why do shod runners with a forefoot strike have the best loading-rates? 21:04 How should someone go about altering their stride? 24:07 What is ‘doming’? 26:35 How could a runner perform weight-bearing exercises while doming? 30:38 Can an injured runner do these exercises? 31:27 Are there significant differences in alignment between runners in shoes and barefoot runners? 32:35 How is dynamic stability affected by footwear from barefoot to minimal to standard running shoe? 38:48 What brands of minimalist shoes would you recommend? 43:07 Where do you see the future of barefoot running going? 45:06 As a barefoot runner, can you run on any surface or are some more preferred? 49:41 How can a traditional runner transition to barefoot running? 55:01 The Final Kick Round Quotes by Irene: “Based on our hypothesis, barefoot running really is the model we should be using in terms of running style because it’s closest to the way that we were adapted to run.   There is something called the “mismatch” theory of evolution that says we’re not using our bodies in the way they were adapted….and saying we’re not eating the food we were adapted to eat. But I like to extend that also to running because I think that the footwear that we have gotten ourselves into….has actually changed the way that we run so that we are not running in a way that we were designed or adapted to run.   We need to be open to new ideas, and you may need to evolve in your thinking. What the truth is today may not be the truth 10 years from now, and the truth 10 years ago may not be the truth today.   Running is in our genes: you don’t need to be taught to run. You run automatically as you develop. It’s one of the motor skills you develop as a child, and so running is something that is innate in us. You do it for survival, and so it shouldn’t be an activity at which we get injured at such a high rate….It would be like birds getting wing injuries or fish getting fin injuries at a high rate.   If you think about it, if you were jumping off a high step and you were going to land in sand, you’re going to stiffen your leg. But if you know that’s concrete that you’re landing in, you’re going to soften your leg. And we do it without even thinking about it….So if you take someone who’s adapted to cushioning and have them run without cushioning, their load rates are going to be much higher.   If you consider the fact that there’s a 52% lifetime risk of developing achilles tendonitis….and most people are heel-strikers, then you start to wonder perhaps if people were landing on the ball of their foot and actually resulting in stiffer, stronger tendons, maybe that rate - that statistic - would be significantly lower.   There is evidence that the more you take away from the foot, the greater tendency you have to land on the ball of your foot….and we have basically shown that forefoot strikers in general have lower rates of loading than mid-foot strikers or forefoot strikers.   ‘Lose the foam and dome!’ ‘Minimal footwear running is science and evolution in perfect harmony.’   Take a Listen on Your Next Run   Want more awesome interviews and advice?

Irene Davis is a renowned biomechanics clinician and scientist. Barefoot running has been one of her areas of focus and she co-authored the Nature paper that received cover attention and created mainstream attention to that topic. She and first author Dr Patrick McKeon, conceived of the idea of a foot ‘core’; if certain foot muscles act as a core it has immediate implications for management in clinical practice. Listen to Professor Davis and see the linked paper (below). Let us know if you agree, disagree. Tweet or write a blog post (email to karim.khan@ubc.ca). One of few researchers who addresses this issue, Prof Davis is a regular keynote speaker at major international conferences. In this BJSM podcast she shares her clinical approach to assessing patients where the ‘foot core’ may be relevant.
