Ground force (or ground reaction force) is one of the most important concepts in modern golf biomechanics. The principle: golfers do not generate power from their muscles pulling the club through; instead, they push against the ground, and the ground pushes back. The forces transmitted through the feet are: vertical (pushing down and receiving the ground pushing up — like jumping), horizontal (pushing sideways to create lateral forces), and torque (twisting the feet to create rotational forces). Elite golfers generate 120-140 percent of their body weight in vertical ground force during the downswing. The squat move at transition, followed by explosive extension, is the ground force sequence. GOATY ENGINE gate measures the weight shift and lower body activation patterns that correlate to efficient ground force production.

Frequently Asked Questions
What is Ground Force in golf?
The forces a golfer exerts against the ground and receives back from it, which are the primary source of power in the modern golf swing.
