My article titled “Measuring Basic Performance Parameters from Video: A Tutorial with Sprinting as an Example” was published yesterday in the US Olympic Committee’s online magazine called Olympic Coach. The article describes how to put together a very inexpensive analysis system comprising a high speed video camera, a Windows laptop and a powerful but free video analysis software program. It gives examples of how to actually measure specific performance parameters for sprinting, including stride rate, stride length, speed, flight time and stance time. These are important parameters that can give the coach indications of over or under striding and asymmetries from one step to the next. With this information the coach can be more precise in designing drills and exercises for each particular athlete.
I am preparing a similar series of articles and videos for the golf swing. I will post them, or links to them here on my blog in the near future. Here is the link to the Olympic Coach magazine; just click on it, then choose the 2011 Summer issue. My article is the last one.
