| 摘 要： | 采用录像解析法,对女子跳远运动员空中技术特征进行研究,探讨空中技术与运动成绩之间的关系,分析不同空中技术对女子跳远运动员运动成绩的影响程度,提出重心抛物线轨迹距离利用率这一新理论。得出3种空中技术对理论重心抛物线轨迹距离的利用率不同,走步式技术对身体重心理论抛物线轨迹距离的利用率最高。

| Abstract: | By using the method of video recording analysis,this paper studied the technique characteristics in the air of female long jumpers,discussed the relations between technique in the air and performance, analyzed the effect extent of technique in the air on the sports result, and advanced a newtheory-utilization ratio to parabola orbit of body center.In the final the authors made the conclusion that the hitch kick style has the highest utilization ratio to parabola orbit of body center. |
