中文摘要:

徐林胤是中国优秀男子沙滩排球运动员，曾与吴鹏根组合，获得2008年北京奥运会第九名，2010年广州亚运会冠军。对徐林胤的跳发球动作助跑起跳环节进行运动学研究，结果表明，徐林胤跳发球动作相对比较成熟，但仍存在缓冲时间过长，最大缓冲时刻膝角稍小，击球点靠后的不足，同时相关部位的肌肉力量的薄弱使得徐林胤跳发球速度受到限制。

英文摘要:

Xu Linyin is one of the elite male beach volleyball players in China. Together with Wu Penggen, he won the 9th place in 2008 Beijing Olympics and the Champion of the Asian Games in Guangzhou 2010. The authors made a kinematic study on the run-up take-off segment of Xu Linyin抯 jumping service. The result shows that his jumping service is relatively mature though there still exist the deficiencies of long buffer phase, small knee angle at the maximum buffer point and backward contact position. At the same time, the weak muscle strength of some his body parts has restricted his jumping service speed.
