Outline of Final Research Achievements

In this study, an instrumented golf club equipped with a combination of a 3D force and torques sensor and a motion sensor was designed to measure the forces and moments exerted by each hand and the manipulating forces which act at both grips during golf swing and points of application of force at each hand were measured.
The results of the analysis of whole body during golf swing indicates that the forces exerted by both hands makes couple force which causes swing rotation of a club in an axis perpendicular to shaft before wrist uncocking, and shaft rotation in long axis of shaft after it.
