I decided to expand on some of the gait information after rereading the biomechanics of sprinting research to ensure the data is accurate. Often orthotics are the cure to things when therapy (joint and tissue) is the solution. Many times sprinting errors stemming from an array of problems can cause additional injury. What about tempo running if it’s not heel striking? What about jumping and orthotics? What is the relationship between hip mobility and the swing phase before touch down? What if a sprinter has a low arch or restriction in his or her first metatarsal? How much free motion does the pelvis have with the top 30 sprinters of all time during their best performances? Often this information is considered a luxury when in reality injuries will happen if what is labeled nice to know. I will post up this Friday in PDF form for track coaches and college strength and conditioning coaches.
