The purpose of this article was to investigate the kinetics that produce the transverse plane rotation of the pelvis during a golf swing. Specifically, the rotation that occurs during the back swing and downswing prior to impact was analyzed using a mathematical process called “induced acceleration analysis.” The swings (with a driver) of 31 low handicap golfers (both men and women) were measured using high-speed motion capture and force plates. Of particular interest to the researchers were the internal joint torques and the timing of the torques at different phases of the back swing and downswing.
