Forget About Your Form and Just Wear the Right Shoe: Biomechanist Dr. Iain Hunter   Every runner dreams of running faster with less effort, with minimal chance of injury.  To do that, we often think we need to “fix” our running form to become more efficient. Dr. Iain Hunter, a running biomechanics researcher, thinks you just might be wasting your time trying to run like someone you are not and tells us what to do instead.   Iain shares his expertise with Coach Claire on topics that include if running mechanics can be improved, footstrikes, how to build strength outside of running, how different types of footwear affect performance, how to know which shoes to choose, and how we can run faster. Iain, a biomechanics professor at Brigham Young University, is also part of a research team that helped determine just how much the controversial Nike VaporFly 4%s really helps you run faster. He shares the results of the study and the actual range of performance improvement attributable to the shoes (Hint: It's not always 4%).  His test subject for the study was none other than Jared Ward, the American Olympic Marathoner headed to London on October 4. Iain has a mathematics education degree with a coaching minor from BYU, followed by a  Master of Education in coaching. During this time, his interest in biomechanics grew, which led him to pursue a PhD in Health and Human Performance at Oregon State University. Iain teaches Biomechanics of Sport and Exercise and conducts research related to the biomechanics of distance running related to performance and injury. He also works with USA Track and Field,  applying his research to elite distance runners. He has been a member of the American Society of Biomechanics since 2003. Iain’s honors and awards include the USA Track and Field: USA Track and Field Sports Medicine and Science and the College of Health and Human Performance: College Teaching Excellence.

Everybody asks, “Is there a proper way to hit the ground?” and “Heel striking is bad”, and “Forefoot striking is good.” Can you talk a little bit about that?   9:49 Runners come in all shapes and sizes. Taller runners are going to have a different cadence than shorter runners. Is that correct?   10:25 What about an athlete that continues to be injured and you look at something about their form. How do you make changes in a form because they really are getting injured from their preferred way of running?   12:55 I would think that if runners practice through their injury, changing their footstrike, that they would eventually learn to prefer that footstrike, but you don’t see that happening?   14:01 You kind of get used to running a certain way that’s right for your own body, and that’s hard to fix, right? So should we as coaches even both trying to change people’s form?   15:09 The most common reasons we think about changing our form is first of all, injury prevention, and second of all, speed and efficiency. We want to become faster runners over longer distances. So you say that it’s just more about practicing running that’ll become a better runner rather than changing our form?   16:11 What about outside of running? Surely you recommend strength training, and physical therapy, and all
