【摘要】：当今,弧圈球技术是乒乓球运动员必须掌握的重要技术手段之一。而反拉弧圈球技术,已成为现下乒乓球比赛中,有效对付弧圈球攻防转换、争取主动的重要技术,也是现代高水平运动员所必须具备的核心技术之一。本文通过文献研究法、实验法、数理统计法与逻辑分析法,以VICON红外三维动作分析系统为主要实验设备,以2016届山西省高校联盟杯的8名男性运动员为受试对象,对其正手反拉前冲弧圈球与反拉高吊弧圈球两项技术动作的运动过程进行分析。通过对乒乓球正手反拉前冲弧圈球与反拉高吊弧圈球技术动作进行分析,获取受试者下肢、重心、上肢与球拍的运动学参数,并找出这两种技术动作之间,所存在的运动特征与差异。本论文的研究旨在为乒乓球正手反拉弧圈球技术动作的训练与教学,提供理论与实践参考价值。并让更多的专业运动员与乒乓运动爱好者可以从根本上认识到两者之间的差异性,为乒乓球弧圈球技术动作的后续研究提供一定的参考。研究结论:1.正手反拉前冲弧圈球与反拉高吊弧圈球两种技术动作各关节运动顺序为踝关节—膝关节—髋关节,然后经过身体躯干的扭转传递至上肢肩关节,然后至肘关节,最后到达腕关节,通过手与球拍,将力量作用于球。2.在整个运动过程中,正手反拉前冲弧圈球与反拉高吊弧圈球技术动作中右侧踝关节出现了明显的弯曲动作,两个技术动作均是从右侧膝关节开始,弯曲角度逐渐减小。并在击球之后,右侧膝关节与髋关节才开始出现伸张现象。3.在正手反拉前冲弧圈球与反拉高吊弧圈球技术动作中,躯干作为下肢的纽带,起到了重要的作用,在这两种技术动作过程中,进行正手反拉高吊弧圈球技术动作时,身体躯干扭转角要大于正手反拉前冲弧圈球时的躯干扭转角。4.在引拍阶段,正手反拉前冲弧圈球技术动作上肢各关节的动作幅度要大于正手反拉高吊弧圈球技术动作,而在击球后的随挥阶段,正手反拉前冲弧圈球的随挥位置主要会偏向前方,而正手反拉高吊弧圈球技术动作中的随挥空间位移会靠前,发力方向为前上方。5.球拍与球接触瞬间,正手反拉前冲弧圈球技术动作拍面与球的俯仰角度会大于正手反拉高吊弧圈球技术动作。
[Abstract]:Nowadays, arc ball technology is one of the important technical means that table tennis players must master. The reverse pull arc ball technology has become an important technology to effectively deal with the transformation of arc ball attack and defense and strive for initiative in table tennis competition, and it is also one of the core techniques that modern high-level athletes must possess. Through the methods of literature research, experiment, mathematical statistics and logical analysis, this paper takes VICON infrared three-dimensional action analysis system as the main experimental equipment, and takes 8 male athletes of the 2016 League Cup of Colleges and Universities in Shanxi Province as the subjects. The movement process of the forehand reverse pull forward arc ball and the back pull high hanging arc ball are analyzed. Through the analysis of the technical movements of table tennis forehand reverse forward arc ball and back pull high hanging arc ball, the kinematic parameters of the subjects' lower limbs, center of gravity, upper limb and racket are obtained, and the relationship between the two kinds of technical movements is found out. The characteristics and differences of motion. The purpose of this paper is to provide theoretical and practical reference value for the training and teaching of table tennis forehand reverse arc ball. And let more professional athletes and ping-pong enthusiasts can fundamentally recognize the difference between the two, and provide a certain reference for the follow-up study of table tennis arc ball technical action. Conclusion: 1. The motion order of each joint is ankle joint, knee joint and hip joint, which is then transferred to the upper limb shoulder joint and then to the elbow joint through the twisting of the torso of the body. Finally, the wrist joint, through the hands and rackets, the force will act on the ball. 2. In the whole movement process, the right ankle joint appeared obvious bending action in the technical action of forehand backpulling forward arc circle ball and back pull high arc ring ball, both of which began from the right knee joint, and the bending angle decreased gradually. And after hitting the ball, the right knee joint and hip joint began to stretch. The torso, as the link of the lower limbs, plays an important role in the technical action of the forehand backward arc ball and the reverse pull arc ball. In the process of these two kinds of technical movements, when the forehand reverse pull up the arc ball technical action, The torso torsional angle is larger than the torso torsional angle when the forehand pulls the forward arc circle ball. 4. In the lead stage, the forehand pull forward arc ball technical action the upper limb joint movement amplitude is larger than the forehand back pull up the arc circle ball technical action, and in the swing stage after hitting the ball, The swing position of the forward arc ball is mainly inclined to the front, while the displacement of the swing space in the technical action of the forward hand pull up the arc circle ball will be forward, and the direction of the force will be the front and upper direction. 5. At the moment of contact between the racket and the ball, the pitch angle between the racket surface and the ball will be greater than that of the forehand reverse pull high arc ball.
