What is the difference between linear and angular speed or velocity and how can something moving in a circle have a linear velocity? I know this is a point of confusion in some golf instructors minds, and I teach basic biomechanics to track and field coaches and this one stumps them too. If you have a rock on a string and you are swinging it in a circle then the string has an … [Read more...]
Pelvic Thrust Biofeedback using AMM3D Golf
This video discusses the pelvic thrust graph in AMM3D with TPI reports. I explain the basics of the curve and then look at an actual example of a golfer with excessive early extension and how we help her fix it using biofeedback drills. If you don’t have an AMM3D system there is still a good drill to help this problem. Put the back of a folding chair behind you at address, … [Read more...]

Two Spine Models: Rigid and Two-Segment
There are several ways to biomechanically represent the spine during the golf swing using motion capture technology, here are two examples, the rigid spine method and the two-segment spine method. Rigid Spine Method The rigid spine method uses markers or sensors to define the left and right shoulders plus the right and left hips. A point mid-way between them is calculated and … [Read more...]
