The purpose of this study was to investigate the rotational movement of the hip, shoulder and in relation to the golf swing mechanics. It was hypothesized that the rotational and twisting movement of the trunk would be important in generating mechanical power that would then be transferred to the club head by arm movement during the golf swing. The subjects were 37 female golfers, including 18 professionals (G-pro) and 19 amateurs (G-ama). Golf swings were filmed with two high-speed video cameras and resultant three-dimensional coordinates were calculated by the DLT method. It was found that maximum club-head speed was attained at impact for both groups, with the G-pro speed significantly greater (p<0.001). Hip and shoulder range of motion, and hip and shoulder angular velocity in G-pro were significantly lager than G-ama. The difference between hip and shoulder angles during the middle phase of the downswing remained relatively constant at 35°in G-pro, compared with G-ama, where the angle decreased throughout the same phase. This study's findings indicate that trunk rotation was a major factor in developing greater club-head speed during the swing of professional golfer when compared to amateurs.
