Analysis on the Situation of the Womenundefineds Volleyball Team in Rio Olympic Games

本文采用文献资料法、专家访谈法、录像观察法、数理统计法、逻辑分析法对巴西里约奥运会中外女排8名自由人的比赛录像,统计女排四强自由人在比赛中接发球中的数据,通过分析、比较,找出女排四强自由人各自的技战术运用特点,并对自由人的运用效果进行分析。研究结果表明:在比赛中,四强自由人接飘球较多,且效果较好;接大力跳发球较少,且效果较差。四强自由人选择正面双手垫球、体侧垫球、跪姿垫球作为主要的接发球技术,但中国女排自由人的接发球到位率较荷兰、塞尔维亚、美国较低,但高于荷兰自由人。在失误率上,四强自由人相差无几。
