| 中文摘要: |
| 采用三维DLT录像解析法对中国女排队员王一梅强攻扣球技术动作进行解析。结果表明，王一梅在助跑阶段的最大水平速度分别为375 cm/s；起跳瞬间两足间距离的长短与起跳时间有密切关系，即两脚间距离越短，起跳时间也越短，起跳动作完成的越快；王一梅空中击球技术特征：击球点高，空中击球前合理运用了躯干向后展体扭转，以加大躯干扭转角度，击球瞬间有助于快速屈体和加快扭转角速度，致使躯干连接部胸骨上缘的速度加快，并依次带动肩、肘、手指掌关节点速度的加快，并达到最高速度峰值。 |
| 英文摘要: |
| Three-dimensional DLT video analysis was applied to analyze the spikes of Chinese women's volleyball player Wang Yimei. The result shows that the maximal level speed of Wang Yimei in run-up is 375cm/s. The distance between the two feet in takeoff has a close relationship to takeoff time, i.e., the shorter the distance between the two feet, the shorter the takeoff time. And the takeoff movement completes quicker. The technical characteristics of Wang Yimei in jumping spike is that she hits the ball at a high point and twists her body backward reasonably before hitting the ball. Thus the body torsion angle is enlarged so as to help bend the body quickly and speed up the torsion angular velocity in hitting. This accelerates the speed of the upper part of the sternum and the speed of the shoulder, elbow, finger and palm joints so as to reach the maximal speed. |
