No one can know how golf players exert forces and moments on the grip handle from the swing motion. Because the club is manipulated by double hands during swing, the upper limbs and the club make a closed multiple-segment loop. In this paper, an instrumented club equipped with strain gauges was proposed to reduce the difficulties of the closed loop problem. The strain sensors provided information about forces or moments, such as 1) torsional moment acting on the grip axis between hands, 2) bending moments at each sensor position, and 3) tensile and compressive axial forces. Unique solution of forces and moments exerted by hands was achieved through force and moment equilibrium conditions using the information. Four varsity golf players volunteered to participate in this study as subjects. They performed tee shots, and they hit the ball as strong as they could. From the results obtained by this study, the both hands acted couple force for angular acceleration of the club, and the top side hands of some subjects acted force which is making acceleration of the club.
