我校800m跑运动员依明江的途中跑技术、运动学特征研究

An analytical research on kinematical characteristics of 800ms runner Yiminjing

文章利用高速录像拍摄法对参加2005年全国大学生锦标赛男子800米运动员依明江途中跑的运动学特征进行分析,得出支撑腿后蹬角度过大和支撑时间过长是依明江步长存在差距的主要原因.

Using quick-speed videotaping method, an analytical research,is proceeded on kinematical characteristics（during middle-distance run） of Yiminjiang who took part in 2005 China coeeges tournament. A difference which mainly exists in step length between Yiminjiang and Tangbaojun is discovered and this difference resuited from the reason that the back stepping angle of Yiminjiang＇s supporting leg is oversized and that supporting time is too long.
