In batting motion, it is impossible to determine the forces and moments acting on the bat with the only visual information about motion of the bat, because the upper extremities and the bat make a closed multiple-segment loop. In this paper, an instrumented aluminum alloy bat equipped with strain gauges was proposed to reduce the difficulties. The strain sensors provided force or moment information, 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. It was shown that existence of intemal forces and moments occurred in batting motion at tee batting.
