A Biomechanical Analysis of Bai Yan's Tennis Service Technique

通过对我过我国优秀男子青少年网球运动员柏衍的发球技术进行三维录像及解析,分析了该运动员的膝关节、持拍手及球拍和上下肢配合的运动特征,认为柏衍采用FB站位技术,侧摆向上引拍,在抛球的方向上把握较好;下肢蹬伸充分,动作比较合理;发球时身体主要环节的用力顺序符合鞭打动作规律,击球点高度比较合理。但是仍有需要改进的地方。

Through 3D video analysis of Chinese young table tennis player, Bai Yan＇s service technique, his knees, rack et-holding hand and cooperation of racket and appendage are studied. Bai Yan applied FB position, baekwing upward from aside, and get a good direction of ball toss; legs are full stretched properly; the strengthen order of major parts of the body correspond with lash role; the height of fiat is rational but still need to improve.
