#86 - Can changing gait reduce running injuries with Professor Bryan Heiderscheit

Dr Glenn McConell chats with Professor Bryan Heiderscheit from the University of Wisconsin in USA. He is an expert on running injuries. This is the third of a series of podcast episodes on running injuries (See Professor Irene Davis’s and Associate Professor Rasmus Østergaard Nielsen’s episodes). Bryan focuses on overstriding and how increasing the stride rate can reduce overstriding and therefore running injuries. The importance of making gradual changes in all aspects. Different kinds of running injuries when land on the forefoot vs the heel. He thinks the type of shoes (minimalist vs cushioned etc) doesn’t make much difference to running injury rates etc. If bouncing up and down when running then may be overstriding which can result in injury. Some people bounce more but don’t overstride, some people overstride but don’t bounce and some do both. Bryan likes to try altering the stride rate/cadence to reduce over striding in an attempt to reduce bouncing and therefore, hopefully, running injuries. Bryan and the previous running. We also discussed causes of hamstring injuries during sprinting. A very interesting chat that brought together not only his research but also the previous two episodes on running injuries.
