摘　　要：运用标准的三维摄像DLT法测量和录像解析的方法,以参加2008年全国第11届冬季运动会速度滑冰500m比赛的18名健将级男运动员为研究对象,对其进行500m比赛疾跑前4步下肢蹬冰技术的运动学研究。通过对运动员疾跑阶段步频、步幅和身体姿态髋、膝、踝关节角度及重心高度、着冰角、蹬冰角的变化分析,指出我国男子速度滑冰优秀运动员在疾跑阶段步频差异不显著,步幅、着冰角和蹬冰角的大小对500m比赛的疾跑速度影响较大。By using the method of calibrated three dimension camera DLT measurement,with the study subjects of 18 male skaters in master sportsman level who participated in the 500m competition in the 11th China winter games in 2008 year,the article has a kinematics analysis of the lower body push technique in the first 4 steps. Basing on the analysis of the kinematic variables such as the stride length and frequency,the angle of hip,knee and ankle joint,the height of gravity center,the contact angle of falling to ice and the push angle,it indicates that for Chinese elite male speed skaters,the difference of stride frequency is not significant in the sprint phase,the magnitude of the stride length,the contact angle of falling to ice and the push angle has more influence on the sprint velocity in 500m competition.
