High Speed Gait Analysis

This year I have access to a high speed film camera that we have been using with the system dartfish to film starts and loads for the bobsled team. I also starting playing around with it filming athletes sprinting, lifting and working out. It's been a pretty interesting to see some of the early results. Here is Bobsled athlete Jessie Beckom pulling a sled. He had been having problems with a right hip flexor/adductor. Under load it gets magnified a bit and you can see how high the left arm is driven to try to compensate for the problem.
