Three methods of beginning the downswing kinematic sequence are explained; they are: Stretching: Proximal segment precedes the distal segment, stretching the muscles, putting them in eccentric contraction hence providing more force for later in the downswing. Riding: Proximal and distal segment turn at the same speed in the downswing, the muscles are in isometric...
I am currently teaching BIO 385 Sport and Exercise Biomechanics at National University in Carlsbad California. It’s an online course and we have a weekly discussion question. Last week it was on angular momentum. Here’s the question: The total angular momentum of a diver changes from zero to some high value during the takeoff...
I recently captured the swings of a young female playing professional on the AMM3D golf full-body motion capture system using TPI 3D analysis. She had some issues with the kinematic sequence peaking order, it was not optimal; her thorax was peaking before her pelvis. I noticed from the graphs that she had both a...
Introduction This article is meant as an introduction to the basics of measuring position in both two dimensions and three-dimensions; specifically to the golf swing. I wrote it a while ago but would like to bring it back and then continue the idea. Position Measurement in Two-Dimensions When we want to measure the position...
