单脚背飞扣球运动轨迹与速度解析

Kinematics Analysis of Motion Locus and Velocity on Backward Flight Spiking with One Foot Taking-off

运用摄影、测试、解析等方法，对两名优秀排球运动员的单脚背飞扣球全程的身体重心、上肢各关节运动轨迹与速度变化的解析，找出单脚背飞扣球较适宜的助跑距离、速度调整方式、起跳方法、起跳角度的控制以及肩、肘、腕关节的鞭打动作方法，使单脚背飞扣球运动技术模式更加完善。

By filming, testing and analysing two elite volleyball players′ whole process of backward flight spiking with one foot taking-off this study found out the proper distance of run-up for the spiking, velocity adjusting, take-off way, take-off angle controling and way of “whip”action of shoulder, elbow and wrist.
