摘要
通过对我国跳远技术与世界先进技术的对比分析,对提高我国跳远成绩的有效途径进行了探讨,认为提高绝对速度能力是提高跳远成绩的最重要的途径;提高运动员快速起跳能力是关键;我国运动员技术上存在起跳腿的着地角较小、起跳扇角大的现象,影响了跑跳结合的连贯性,对获得腾起垂直速度不利;此外,还存在摆动腿的摆动时机晚、摆动速度慢、摆动幅度小等因素,这些都是影响我国跳远成绩提高的重要原因。
Mechanical analysis of the techniques of Chinese long-jumpers and technical comparison between them and world level athletes show that there are effective ways in improving Chinese long-jumpers' performance: to increase jumpers' absolute speed is the final method of improving their approaching speed, to enhance their ability of fast take-off is a shortcut to improve performance;and the most effective ways are to perfect jumpers'techniques in obtaining larger touch-down angle of take-off leg to avoid unnecessary speed loss during take-off, and producing higher swing speed and larger swing amplitude of free-leg during takeoff to get the optimum angle of take-off
