Abstract

This study focused on the investigation of the changes of the anterior and posterior forces (AP forces) of professional golfers. The subjects were three professional male golfers. Four clubs swing (driver, iron 3, iron 5, and iron 7) for each subject were taken by two high speed video cameras. Two AMTI force platforms were used to measure the AP forces simultaneously. AP force generate CCW moment from the start of backswing to the club vertical, and CW moment until club horizontal in the downswing. Direction of this moment changes again after the club horizontal in the follow through. The sum of AP forces generates forward moment to the golfer’s body in the fore phase of downswing. After this time, the sum of AP forces generates backward moment until the club vertical in the follow through.
