在投掷项目中旋转技术练习时,通常采用拉橡皮筋克服阻力的旋转练习,该练习存在旋转时橡皮筋缠绕在运动员身体上的高度不固定及橡皮筋阻力不恒定的问题。为了解决运动员在旋转技术出现的问题,本文介绍一种投掷旋转训练装置(如图),所述装置包括固定轴1、卷绳框架2、电机阻尼器3、卡件4、圆环5、固定带6和钢丝绳7;阻尼器内设有多个顶针,卡件包括第一轴承、拉环、短轴和侧板,短轴设置在卡件两个侧板的一端,拉环设置在卡件的另
Spinning practice in the throwing project, usually with rubber band to overcome the resistance of the rotating practice, there is rotation of the rubber band wrapped around the athlete’s body height is not fixed and the rubber resistance is not constant problem. In order to solve the problems of the athletes in the rotation technique, a throwing rotation training device (as shown in the figure) is introduced in this paper. The device includes a fixed shaft 1, a rope frame 2, a motor damper 3, a clamping member 4, a ring 5, A plurality of thimbles are arranged in the damper, a first bearing, a pulling ring, a short shaft and a side plate are arranged on the damper, the short shaft is arranged on one end of two side plates of the clamping piece, the pull ring is arranged on the clamping piece The other
