项目摘要
The aim of this study is to clarify the posture of hand and forearm during the topspin racket swing and to reduce the wrist injury that occurs by hitting topspin. The angle of wrist joint during the racket swing of topspin was measured, and the difference of Euler angles between the western grip and eastern grip was compared. On the other hand, maximum torque of circumference of 3 axes of wrist joints was measured, and it compared with that of actually swinging a racket. And these torques differ little even in the grip angle of western and eastern. But comparing the Euler angle, eastern grip uses radial flexion and western grip uses the pronation mainly. The pronation has much flexibility and also it has much power than radial flexion. That means the western grip has possibility to reduce the injuries.
本研究的目的是明确上旋球拍挥动时手和前臂的姿势,减少击打上旋球时发生的手腕损伤。测量上旋球挥拍时腕关节的角度,比较西式握拍与东式握拍的欧拉角差异。另一方面,测量腕关节3轴圆周的最大扭矩,并将其与实际挥动球拍的扭矩进行比较。即使在西方和东方的握把角度上,这些扭矩也几乎没有差异。但与欧拉角相比,东握法以桡屈为主,西握法以内旋为主。内旋具有很大的灵活性,并且比桡屈具有更大的力量。这意味着西式握法有可能减少伤害。
