バドミントンラケットグリップの握り易い形状の効果

抄録

This study was investigated the effect of the hand-made badminton racket grip. The parameters of the comparison measured the shape of the grip, the movable angle at wrist joint, the contact area between hand and grip. Additionally, the EMG activity during racket swing motion was measured for two minutes, and the grip strength was measured before and after in racket swing. The characteristics of the hand-made grip became thick of the intermediate portion of grip. The movable angles in the palmar-flexion and the dorsi- flexion and the radial- flexion increased in the hand-made grip. The contact area between hand and grip in the hand-made grip increased significantly in the index finger, middle finger and ring finger. There was no difference in the EMG activity during the racket swing motion between the ready-made grip and the hand-made grip. The grip strength of the swing in the ready-made grip was decreased significantly both before and after compared to the hand-made grip. It was considered to enjoy the badminton sport to people of a wide range of age, and it was also important to fabricate a grip on their hand.
