The key to swing velocity, club head speed, and distance is biomechanical reaction through postural control

For maximum power creation in the golf swing, with minimal negative stress on the body, the ground must be the first link in the kinetic chain of energy transfer. Newton’s third law of motion tells us that using our feet and legs to drive forcefully into the ground results in the ground pushing back up into the golfer’s body with an equal magnitude of force. The force the ground transfers into the golfer is known as the ground reaction force (GRF). GRF is then transferred up the kinetic chain, first through the feet then the legs and into the pelvis, then up into the golfer’s core, shoulder complex, arms, and, finally, the golf club and ball. Controlling the transfer of this energy up the kinetic chain from the ground to the ball with the most efficiency is what allows the golfer to create the most force your body will allow, which leads to the greatest distance the ball will travel. A golfer’s body depends on three systems to control this neurological, sensory, and musculoskeletal.
