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 phase. Miller and Munro (1985) reported that Greg … [Read more...]
15 Minutes of Biofeedback Training improves the Kinematic Sequence
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 little excessive sway in the backswing and a reverse spine angle … [Read more...]
2D and 3D Coordinates for Golf Swing Analysis
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 of something on a flat plane, say a piece of paper or … [Read more...]
