The purpose of this study was to investigate the contribution of joint torque to the acceleration of the club during the downswing phase in golf. Three professional golfers volunteered as participants (age: 37.7 ± 4.5 years, height: 1.70 ± 0.03 m, weight: 63.3 ± 4.3 kg). Their driver shots were recorded using a 10-camera (250 Hz) VICON system. The forces and torques applied to their drivers during the downswing phase were calculated based on Newton-Euler equations. Joint force power and joint torque power were also calculated. The mechanical work was obtained as an integral value of the power during the downswing phase. The mechanical work done by the joint torque accounted for about 15% of the total mechanical work in the downswing phase. Therefore, these results suggest that the grip torque applied to the club plays an important role in power generation in a golf swing.
