One of the main questions I get asked is how to I break down movement? I think this is part of the problem of biomechanical analysis. We break things down so much we lose what we are actually looking for. People argue about what kinematic variables matter most. What numbers to

Look for and when. “How much X and how much Y and how much Z should he have?” The numbers are important but they should help explain and clarify what you see with your eyes. My greatest advice to all my students is learn to analyze a pitch qualitatively before I teach you what

The numbers mean. Unless we can describe the movement as a whole, unless we can identify movement quality and efficiency holistically then we fall into petty arguments about whether or not a pelvis should have a 600 or 700 degree/second velocity. We’ve chopped a pitch up so much

We sometimes lose the ability to make meaning out of the numbers at all. Pelvic angular velocity is relative to the entire continuous movement(as is every kinematic variable). Nothing happens in isolation. Why do we analyze in isolation?
