【摘要】：在网球运动中,通过拍弦与球的接触来改变球的运动,网球拍弦作为球拍与球接触的媒介,拍弦的张力的不同对击球效果和人体承受载荷均会产生重要的影响,但目前国内外的研究结果不尽一致。本文采用Trigno无线肌电采集系统、YSV动态加速度信号采集系统、YSV动态应变仪及便携式雷达测速枪,对北京体育大学网球专项的15名男性二级运动员使用低、中和高三种不同张力拍弦的球拍进行正手击球时的运动学、动力学和前臂表面肌电数据进行采集,同时按照ITN国际网球等级测试的方法对击球的精度和深度进行了评价,来研究球拍拍弦的张力对正手击球效果和前臂所受冲击载荷的影响,以期为网球运动的参与者对网球拍弦张力选择及预防肌肉关节损伤提供理论和实证依据。通过对采集到的数据进行分析研究,得出以下结论：从击球效果来看,54磅拍弦的击球效果最好,从击球时前臂肌肉的主动负荷来讲,54磅张力亦最低。
[Abstract]:In tennis, the movement of the ball is changed by the contact between the racket string and the ball. The tennis racket string is the medium of the contact between the racket and the ball. The different tension of the racket string will have an important influence on the batting effect and the load bearing on the human body. But the research results are not consistent at home and abroad. In this paper, the Trigno wireless electromyography acquisition system and the portable radar velocimetry gun are used to collect the dynamic acceleration signal of YSV. The kinematics, dynamics and electromyoelectric data of forehand were collected from 15 male secondary athletes in Beijing University of physical Education, who used rackets with low, middle and high tension to hit the forehand. At the same time, according to the ITN international tennis grade test method, the accuracy and depth of the stroke are evaluated to study the influence of the racquet string tension on the forehand batting effect and the impact load on the forearm. In order to provide theoretical and empirical basis for tennis players to choose the string tension of tennis racket and prevent the injury of muscle and joint. The following conclusions are drawn: the 54 lb string is the best shot and the 54 lb tension is the lowest in terms of the active load of the forearm muscles when hitting the ball.
