摘要
采用三维高速摄像系统对我国参加 1998年亚运会选拔赛达到健将以上水平的 7名女子跳高选手起跳前后的一些技术进行分析,发现:我国选手在起跳瞬间的垂直速度有一定提高,H_1、H_2 与世界选手之间有一定的差距,差距在于:起跳离地瞬间踝关节、膝关节及髋关节的蹬伸不够,起跳前一步至蹬摆幅度小。
Three-dimensional high speed photography was used for a kinematical analysis of high jumpers' techniques just before and after take-off. 7 elite Chinese female high jumpers taking part in the trials for 1998 Asian Games served as subjects. The results showed that the vertical speed of take-off of Chinese jumpers were good but their H1 and H2 were lower than that of world level high jumpers. Their driving of ankle, knee and hip joints was lower at the moment of take-off and their swing range was smaller at the last step for take-off.
