Spine Flex Analysis Pt 1

Analysis of 3D motion capture data from a basic K-Vest TPI system identifies key movements in the golf swing that are essential for the efficient transfer of power to the club. Timing of the flexion (forward bend) of the thoracic spine with pelvis rotation is a central factor in this story that we will examine in future articles. 

Here are some of the data from our swing motion analysis of a scratch golfer who wants to relate swing mechanics to club performance. His goal is to achieve increased distance. The results reveal how he generates power, what happens in the downswing to limit clubhead speed, and what would be the most effective combination of swing and club adjustments to achieve lower scores. 

The upper left panel shows the club path through the initial part of the downswing at a capture rate of 180 times/sec. The lower left panel shows the pelvis-upper body-hands (club) kinematic sequence of a golf swing. The other panels break down this sequence into "bite-sized" pieces for analysis.
