#657 From the Ground Up: The Biomechanics of Elite Clubhead Speed

Traditional video analysis shows what happens in the golf swing, but not why. Only 3-D biomechanics reveals how joint motion, pressure transfer, Ground Reaction Forces (GRF), and the kinetic sequence create clubhead speed.

Elite speed does not come from swinging harder or rotating the pelvis faster. It begins with efficient force production against the ground and a perfectly timed transfer of energy from the feet to the clubhead.

The downswing consists of three phases:

Shift: Pressure moves into the lead foot. The lead ankle dorsiflexes, the foot stiffens, and the pelvis organizes for…
