摘要
起跳技术是背越式跳高的关键技术,也是决定跳高成绩的主要原因之一。通过对参加2008年全国田径大奖赛(乌鲁木齐站)总决赛前5名运动员的研究,探讨其起跳技术的运动学特征。结果表明:我国女子跳高运动员起跳缓冲阶段起跳腿的缓冲幅度较小;在起跳腿蹬离地面瞬间的蹬伸幅度不足,水平速度转化率较低;身体重心高度及起跳腿工作距离都比较小。并针对这些问题提出一些相关的建议。
The take - off technique is the key technique in back jump as well as an important factor determining the performance. This article takes as research subject the top five jumpers in the Urumqi Stage of 2008 National Athletics Grand Prix. The kinesiological features of their take - off techniques are discussed. It is indicated that the buffer room for the take - off leg in the take - off buffer stage for Chinese female high jumpers is comparatively small. The kick - stretch room for the moment when the take - off leg leaves the ground is not enough. The conversion rate for the horizontal speed is low. The height for the body center of gravity and the working distance for the take - off leg are small. In view of these problems, the thesis writers give suggestions.
