| 摘 要： | 运用文献资料法、访谈法、三维摄像法和录像解析法,对河北省三代女子铁饼奥运选手肖艳玲、宋爱民、苏欣悦和陈扬的投掷技术进行对比研究。结果表明,4名运动员在动作节奏方面存在差异,肖艳玲旋转速度较慢但幅度大,其他3人旋转速度较快,但旋转过程中身体和投掷臂相对放松;宋爱民腾空阶段用时最短且保持了加速趋势,其他3人在腾空阶段的旋转速度都出现了明显下降;4名运动员在转换阶段对身体和投掷臂都进行了很好的控制;在铁饼出手瞬间,肖艳玲、宋爱民和苏欣悦的左侧支撑十分稳固,且右髋的转动与右腿的蹬伸都非常充分,而陈扬的左侧支撑和右侧蹬转都存在不足。

| Abstract: | This paper makes a comparative study on throwing techniques of three generations of women discus Olympians Xiao Yanling,Song Aimin,Su Xinyue and Chen Yang in Hebei Province by using the methods of literature,interview,three-dimensional photography and video analysis.The results show that there are differences in the rhythm of movement among four athletes.Xiao Yanling had a slow but large range of rotation speed,while the other three rotated faster,but the body and throwing arm were relatively relaxed during the rotation.Song Aimin took the shortest time in keeping the trend of acceleration,while the rotation speed of the other three people decreased significantly in the flight phase.The four athletes had well controlled the body and throwing arm during the transition phase.At the moment of discus release,Xiao Yanling,Song Aimin and Su Xinyue’s left support was very stable,and the right hip rotation and right leg extension were very sufficient,while Chen Yang’s left support and right leg rotation were insufficient. |
