摘　　要：采用技术动作录像、影片分析以及数理统计等方法,通过对我国10名优秀女子跳高运动员助跑最后两步和起跳速度变化特征的运动学分析,提出我国优秀女子跳高运动员最后两步缓冲动作稍大,摆动腿蹬离地面时速度水平较低;大部分运动员身体重心高度波动较大;起跳垂直速度水平与起跳时间有较高的相关性;运动员起跳结束瞬间的垂直速度水平差别较大,但整体水平一般。By the methods of technique action records, video analysis and mathematical statistics, this paper analyzes characteristics of the last two run-up steps and taking off speed of our excellent woman fosbury flop high-jump athletes. It puts forward that the last two steps＇ buffer action of them is slightly big; speed level of the swing legs is lower when they stretch away from the ground. Body heart height largely fluctuates of most of the athletes;There is a higher relativity between jump vertical speed level and jump time;There is a great difference of athletes vertical speed level at the end of their jump, but the level of the whole is general.
