DYNAMICS OF CLUB HEAD VELOCITY DURING GOLF SWING
Keywords: golf, dynamics, club head velocity
AbstractThe purpose of this study was to identify the dynamics of club head velocity during a golf swing. Three professional golf players hit a golf ball to the net placed on a hit ball direction. Three dimensional kinematic data of swing motions were collected using motion capture system (VICON NEXUS). Dynamic equations were derived to determine the contributions of the torque and force acted on the grip, motion-dependent and gravity element to the club head velocity. The results were summarized as follows. The elements of the force acted on the grip and the centripetal acceleration were the main causes of the club head speed at the impact. The torque element acted on the grip contributed to the club head speed at the beginning of the swing.
