Precision Measurement of 3D Forces/Torques at Each Grip During Golf Swing

Abstract

Golf club is manipulated by both hands and arms which consist closed link structure. Since the closed link structure can move fast the club and transfer the energy of trunk and lower body into the club directly, it is important to understand how golfer manipulates the golf club using both arm forces and torques acting at each grip. In this study, the manipulating forces which act at both grips during golf swing were measured using a 3D forces and torques sensors and motion capture system with high accuracy for understanding how human utilize force redundancy to control the golf swing. The results revealed that a golfer utilize high internal forces acting on the grips which does not contribute the movement of golf club in order to manipulate the golf club.
