采用文献资料法、数理统计法和逻辑分析法,对柏林世锦赛跳远项目前8名的技术数据进行分析。结果表明:世界优秀跳远运动员运动寿命长,基本可以在前3跳跳出个人最好成绩,踏板准确度高,落地损失距离对成绩的影响较小;最后10 m分段速度、11~6 m阶段平均速度与运动成绩、起跳着地时刻重心下降的幅度与起跳离地时刻垂直速度、起跳阶段膝关节最小角度与着地角、离地时刻大腿与水平面的夹角同摆动腿摆动角速度等技术数据之间具有显著性相关,但是男女存在较大差异;男女最后2段速度变化趋势相反,最后3步的步速具有先增后减的变化特征;起跳角度和起跳离地时刻垂直速度有上升的趋势,水平速度损失和损失率有下降趋势;男女离地时刻摆动腿与水平面夹角的平均值为负值,女子摆动幅度更小,男子摆动腿摆动角速度明显下降,女子则表现为上升。
By using the methods of literature review, mathematical statistics and logical analysis, the technical data of the top 8 long jump project in Berlin World Championship were analyzed. The results show that: the world long jumper has a long service life and basically can get the best result in the first 3 hops, and the pedaling accuracy is high and the impact of landing loss on performance is small. The final 10 m segment speed, 11-6 m stage The average speed and the athletic performance, the descending amplitude of the center of gravity at the moment of take-off and landing, the vertical velocity at the moment of departure from the ground, the minimum angle of knee joint during the take-off phase and the ground angle, the angle between the thigh and the horizontal plane at the moment of departure, There was a significant correlation between male and female, but there was a big difference between male and female. The trend of the last two stages of male and female was opposite. The last three steps had the characteristics of first increasing and then decreasing. The vertical speed of take- Horizontal speed loss and loss rate have a downward trend; the average angle between the swinging leg and the horizontal plane when the male and female take off the ground is negative, the swing range of the female is smaller, the swinging angular speed of the swinging leg of the male is obviously decreased, while the female is shown to rise.
