不同水平网球选手正手击球技术运动学研究

Kinematic Study on Tennis Players' Forehand Stroke Skill

在网球的基本技术中,正手被视为发球后最重要的一项技术,采用文献资料、测量等研究方法针对国内12名男子网球选手正手击球技术的特征展开研究,重点了解与击球技术动作相关的关节角度,线速度和角速度等运动学特征,旨在揭示不同水平选手技术动作的差异,并进一步认识影响正手击球速度的核心要素。结果表明与一般水平选手相比,优秀选手在正手击球瞬间表现出更快的拍头水平速度和更快的肩部水平速度,但在躯干转动的角速度上却不存在显著性差异。在不考虑组别的情况下,击球时过程中选手的肩、髋、球拍的转动角差异很大,说明考虑标准化的技术动作并没有实际意义。

In the basic skills of tennis,forehand is considered the most important skill after serve. This study analyzed 12 male China tennis players＇ forehand stroke skill features by the methods of literature review and measurements. For the purpose of revealing skill differences between players with different levels and further understanding the core elements impacting stroke speed of forehand,this study focused on joint angle,velocity and angular velocity features which are related with batting action. The results showed that compared with the general players,outstanding players have a faster head level and a faster shoulder level at forehand stroke moment. But the trunk angular velocity has no significant difference. Without considering the group case,rotation angles of players＇ shoulder,hip,and racket have obvious differences,which indicates that considering standard skill movement doesn＇t have practical meaning.
