我国优秀女子撑竿跳高运动员悬垂摆体技术的运动学特征

Kinetics Analysis of Swing with Hang Technique for Chinese Elite Women Pole Vaulters

通过对10名优秀女子撑竿跳高运动员的悬垂摆体进行运动学研究,结果表明:我国优秀女子撑竿跳高运动员在竿上支撑阶段时间的分配上存在问题;运动员都能很稳定地保持合理的身体姿势;悬垂时下握手的肘关节角度偏大;我国优秀选手在竿弦最短时竿弦与地面的夹角过大,竿子的弯曲度不够,造成竿子的能量储备不够。我国运动员的摆体技术基本上是以“高髋摆体”技术为主。

Through kinetics analysis of ten elite Chinese women pole vaulters＇performances of swing with hang , the author has concluded that the time distributed to pole - holding is not reasonable, the angle between elbow and the nether hand is comparatively big during hang and so is the angle between the pole and the ground, the degree of curvature of the pole is not enough to store up abundant resilience force. Most Chinese pole vaulters＂ swing with hang technique is generally characterized by hip swing.
