摘要

网球发球是赢得比赛的重要组成部分。本研究分析网球发球速度的机制，并将10名网球运动员分为两组。一组进行常规训练，另一组在常规训练的基础上通过松紧带在肩部进行辅助训练。这些动作被相机拍摄下来并进行分析。结果表明:实验结束后，两组的投掷高度和击球高度均有提高，A组与B组比较p < 0.05;抛球后球偏转角度减小，但B组提高幅度较A组更显著(p < 0.05);B组的服务速度和成功率也有显著提高，即B组的表现更好(p < 0.05)。结果表明，肩部训练对提高发球速度有积极作用，视频分析方法在训练中可靠，有利于提高训练效率。

Study on the Effect of Shoulder Training on the Mechanics of Tennis Serve Speed through Video Analysis

Tennis service is an important part of winning a match. This study analyzed the mechanics of tennis serving speed and divided ten tennis players into two groups. One group carried out conventional training, while the other group carried out auxiliary training on shoulders through elastic band besides conventional training. The actions were photographed by cameras and analyzed. The results showed that the throwing height and hitting point height of the two groups improved after the experiment, and p < 0.05 in the comparison between Groups A and B; the ball deflection angle reduced after throwing, but the improvement of Group B was more significant compared to Group A (p < 0.05); the service speed and success rate also significantly improved in Group B, i. e., the performance of Group B was better (p < 0.05). The results show that shoulder training plays a positive role in improving the service speed and the video analysis method is reliable in training, which is conducive to improving the training efficiency.

期刊介绍： The field of biomechanics concerns with motion, deformation, and forces in biological systems. With the explosive progress in molecular biology, genomic engineering, bioimaging, and nanotechnology, there will be an ever-increasing generation of knowledge and information concerning the mechanobiology of genes, proteins, cells, tissues, and organs. Such information will bring new diagnostic tools, new therapeutic approaches, and new knowledge on ourselves and our interactions with our environment. It becomes apparent that biomechanics focusing on molecules, cells as well as tissues and organs is an important aspect of modern biomedical sciences. The aims of this journal are to facilitate the studies of the mechanics of biomolecules (including proteins, genes, cytoskeletons, etc.), cells (and their interactions with extracellular matrix), tissues and organs, the development of relevant advanced mathematical methods, and the discovery of biological secrets. As science concerns only with relative truth, we seek ideas that are state-of-the-art, which may be controversial, but stimulate and promote new ideas, new techniques, and new applications.
