本研究从抛球精度、助跑速度、起跳角度、挥臂弧度、击球高度、落点难度等6个方面,对优秀男排运动员大力跳发球技术的各环节因素进行分析,以期能够为大力跳发球技术的训练提供一点参考。1.抛球精度:抛好球是发好球的基础,对保证大力跳发球的质量起到至关重要的作用。抛球精度主要涉及抛球手的选择、抛球的旋转、抛球的高度和抛球的距离等问题。(1)抛球手的选择:采用右手发球右手抛,这样做跳发球的节律性更好,因为,右手抛球后事先为右手发球准备了一个摆臂动作,使整个动作有机地连为一体,效果更好。
In this paper, we analyze the factors that lead to the elite male volleyball players jumping vigorously from six aspects, such as throwing accuracy, running speed, take-off angle, swinging arm arc, striking height and falling point difficulty, Serve technical training to provide a little reference. 1. throwing accuracy: throwing the ball is the basis for the ball, to ensure the quality of the ball to play a vital role. The accuracy of throwing mainly involves the choice of the throwers, the rotation of the throwing balls, the height of the throwing balls and the distance of throwing the balls. (1) The choice of tossing player: using the right hand tossing, the rhythmicity of jumping serve is better because after the tug of the right hand, a swinging arm action is prepared in advance for the right hand tipping to organically connect the whole action ,Better results.
