| 摘 要： | 采用动态摄像测量,运动录像解析方法,参照国内外优秀男子标枪运动员投掷步最后一步技术的某些运动学参数,对李荣祥投掷标枪最后一步的技术情况进行生物力学分析。结果认为,李荣祥最后一步右脚着地时,应适当抬起躯干,加大身体后倾角值;标枪出手瞬间,克服屈髋现象,加大出手时的右髋角。

| Abstract: | By using the method of camera measurement and photographic analysis, contrasting some kinematic parameter of last step technique of elite javelin throwers at home and abroad, this paper makes biomechanical analysis on last step techniqueof LI Rong-xiang. The result shows that his body should rises a little when right foot touches the ground. When releasing the javelin,he should avoid bending at hip. |
