我国优秀女排队员接发球技术的三维运动学比较分析

一传到位率偏低和失误率较高是新一届中国女排亟待解决的主要问题之一。通过三维高速录像分析,揭示了我国4名优秀女排运动员接跳飘球技术动作的运动学特征。周苏红和张娴的动作具有移动判断准确,击球点在体前低于身体重心,下肢蹬伸用力幅度小,手臂上抬幅度较大的特点;杨昊和殷茵的动作具有移动判断不够准确,击球点在体侧高于身体重心,下肢蹬伸用力幅度大,手臂上抬幅度大的特点。研究认为移动判断准确,击球点低于身体重心,上下肢协调蹬伸用力有利于提高接发球的到位率。

The Three- dimensional Kinematical Comparative Analysis on Receiving Service Techniques of Some Chinese Elite Women's Volleyball Players

A higher rate of failure and low accuracy of Transmission in place are two problems for Chinese women’s volleyball team and remain yet solved.This research,through three-dimensional high-speed video analysis,revealed Volleyball 4 outstanding Players’ floating ball techniques in term of its jump Kinematical characteristics.Zhou Su-hong and Zhang Xian of the action have such technique features as accurately moving so as to determine the sweet spot in front of body center of gravity lower and lower limbs Push the small magnitude of force with arm elevation featuring a large extent.While Yang-Hao and Yin-Yin boast such features as they do not move accurate enough with the sweet spot in the side of the body above the center of gravity and enjoying force large range kicking leg,arm elevation range Great features.It is believed that the move to accurate determination with hitting of the center of gravity point lower than the body and coordination of kicking force on the lower extremities can improve rates of return of serve in place.
