On sport players using raket and bat and general persons, sensory evaluation of the optimum diameter in grasping cylindical object and the movable angle of wrist joint under the grasping were investigated, and the effcts of the fingers in the six movements of wrist joint (Horizontal movement : Palmar-flexion and Dorsi-flexion, Vertical movement : Radial-flexion and Ulnar-flexion, Twist movement : Supination and Pronation) were investigated using stress sensors attached on the fingers. The subjects were ordinary persons and players of badminton, baseball and tennis, and the obtained data were compared to each other. The optimum diameters of the grasping evaluated by sport players were ranging from 30 mm to 40 mm, these values were same as that of ordinary persons, and the average values of optimum diameter were almost same as grip diameters of raket and bat. About movable angle of wrist joint under the grasping, badminton players could move horizontally and twist at larger angle and fielders could move vertically at larger angle. About the grasping force of fingers, the maximum force was exhibited at the tip of index finger for sport players, on the other hand, it was exhibited at the tip of middle finger for ordinary persons. It was considered that the specific training has effect on the sport players in the movable angle of wrist joint and in the finger's way of using at the movement of wrist joint.
