刘翔110米栏第5栏攻栏蹬伸阶段技术特征的剖析

Technical feature analysis of attack into the hurdle stage of the 5th hurdle of 110 metres hurdles of LIU Xinag

采用文献资料、高速摄录解析和比较分析等方法,对刘翔110m栏两次比赛第5栏攻栏蹬伸技术进行了分析,并与同场竞技110m栏选手若干技术参数相比较。结果显示:刘翔110m栏第5栏起跨攻栏意识强,着地角大,支撑时间短,起跨角小,攻栏速度快,身体重心腾起角小。符合该项目运动学特征及当今世界跨栏技术发展趋势。

With document information, high speed camera and computerized film analyses, comparative analysis, etc. for Liu Xiang in the 1 lOre hurdle twice the match the analysis of the 5th attack into the hurdle technology to analyse, and with its same site sports the hurdle player some technical parameter of 110m compare comparatively. It has been shown＇that： From Liu Xiang＇ s the 5th of 110m hurdle, the takeoff and attack into the hurdle consciousness, is strong;the landing angle, is larger;the support time, is short;the takeoff angle, is less to attack into the hurdle speed, is rapid;the takeoff angle of bady＇s center of gravity, is little. It accords with this event kinematic feature and the present world technical development of the 110m hurdle race tendency.
