#84 - Effect of shoes and gait on running injuries with Professor Irene Davis

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.
