摘要
运用三维摄像方法对2011年世界女排大奖赛总决赛澳门站美国、巴西、中国3名中外优秀女子排球副攻运动员3号位向2号位移动拦网技术进行现场拍摄,旨在揭示拦网技术动作各环节运动学特征和规律。研究表明:美国和巴西女排运动员拦网技术较好,准备充分,判断准确,移动迅速,摆臂积极,起跳速度快、重心高度高、肩的高度高,拦网击球瞬间其髋角小、肩倾角小,躯干姿势以髋关节为中心呈"<"型,滞空时间长,落地技术动作衔接紧密,呈现出男子排球拦网技术的特点。
By the method of three - dimensional high - speed camera, the author shots the film on blocking technique of 3 elite female volleyball players from USA, Brazil, China in 2011 FIVB World Grand Prix Finals, who move to block from the center front position to the left front position. Its aim is to prompt kinematic characteristics and reveal laws of the blocking ac- tion. The results shows that the United States and Brazil women volleyball athletes blocking actions boast men＇ technical fea- tures. Their take -off speeds are faster, their heights of center of gravity arc higher, their heights of shoulders are higher, their times staying in the air are longer, their blockings are harder. It has become the world women volleyball player blocking technology development trends.
