摘 要: 采用文献资料和录像解析方法,对比分析中外优秀男子跳高运动员起跳阶段的水平速度、垂直速度、身体内倾角、身体重心、支撑腿膝关节角及重心的垂直工作距离等运动学参数。找出他们起跳阶段的运动学差异。结果表明:我国运动员的助跑速度与起跳腿的专项力量素质不相匹配,水平速度利用率低;人体过早的倾斜,起跳偏心角过大形成不合理的腾起角,导致起跳腿蹬伸不充分,垂直工作距离短,垂直速度小。 Through the methods of literature review and video -watching of elite Chinese male high -jumpers, this paper discovered that the difference of take - off technique about Chinese excellent high jumper and world excellent high jumpers through comparing kinematics'parameters. It Comparative analyses the kinematic parameters of the take- off stage, the Horizontal velocity, the vertical velocity, the body angle, the body center of gravity, the knee - angle of the supporting leg and the center of gravity etc. The results show : The special strength of take - off leg of Chinese male high - jumpers does not match with their run - up speed, Inefficient use of horizontal velocity, the body tilt too early, the body tilt - angle too much lead to the take - off - angle, inadequate pushing of the take - off leg leads to the short vertical working distance of the body and small vertical velocity. It provides a reference for teaching and training of the high jump.
