This article studied the knee moments created during the golf swing in the frontal plane. The authors sought to determine the effects of modifying the foot position of the target (front) leg on the external moments (torque) on the target side knee. They studied 7 collegiate golfers hitting balls while standing with the front leg on a force plate. After a warm-up, each subject completed 5 swings with the target foot pointing straight ahead (perpendicular to target line) and 5 trials with the foot rotated 30 degrees towards the target. The order of foot positions was randomized.
