【摘要】：研究目的:本文旨在通过8个高速摄像头对刘诗雯反手拉下旋、上旋球的技术动作进行拍摄,并通过motion分析软件对各关节点进行识别及解析,获得相应的运动学参数。对上肢、躯干、下肢的运动学特征进行分析,揭示刘诗雯技术动作的运动规律,通过研究期望能对乒乓球竞技后备人才的培养留下详实、客观的数据储备,也为女子高水平运动员训练提供参考。研究方法:本研究运用文献资料法、专家访谈法、运动学测试与分析法、数理统计法,对优秀运动员刘诗雯反手拉下旋球、上旋球技术动作进行研究,主要通过对所获得的时间参数、空间参数以及各关节角度等数据进行解析。研究结论:刘诗雯反手拉下旋球技术动作周期中,引拍阶段和挥拍击球阶段用时间多,占得比例大;随挥阶段用时最少。刘诗雯反手拉上旋球动作周期中,引拍阶段和还原阶段用时多,占得比例大;击球阶段用时较少,比例最小,此阶段瞬间获得瞬间加速。建议:1.在青少年乒乓球训练中,在推广女子快速力量型打法时,反手拉下旋和上旋球技术可以以刘诗雯的动作技术为模板,会提高训练效率。2.应该对优秀运动员的技术动作进行更多生物力学测试,建立关键技术动作的模板和数据库,为运动员的技术动作训练、监控和诊断打下基础。3.刘诗雯发手拉下旋球技术显示速度力量型特征,通过下肢蹬伸、躯干的扭转以及上肢的“鞭打”动作,最终将能量传递到球拍,力量集中、爆发力强。4.刘诗雯反手拉上旋球技术在力量方面还有提高空间,需要提高控制球的旋转和压弧线的能力。拉上旋球技术中,刘诗雯上肢肌肉放松,动作迅速,击球时力量较大,充分利用了下肢和躯干的力量。
[Abstract]:The purpose of this paper is to use 8 high speed cameras to shoot the technical action of Liu Shiwen's backhand pull down and top spin ball, and to identify and analyze each node by motion analysis software, and obtain the corresponding kinematics parameters.This paper analyzes the kinematics characteristics of upper limbs, trunk and lower limbs, reveals the movement rules of Liu Shiwen's technical movements, and expects to leave a detailed and objective data reserve for the cultivation of table tennis reserve talents.Also provides the reference for the female high level athlete training.Methods: in this study, the methods of literature, expert interview, kinematics test and analysis, mathematical statistics were used to study the technical movements of Liu Shi-wen, who pulled the ball back and turned the ball up.The time parameters, spatial parameters and joint angles are analyzed.Research conclusion: Liu Shiwen backhand pull down spin ball technical action cycle, the lead and swing stage of the more time, large proportion; with the swing stage the least time.Liu Shi-wen used more time in the backhand pull up spin action cycle and occupied a large proportion in the leading stage and the restore stage, while in the batting stage, the time was less and the proportion was the least, and the instant acceleration was obtained in this stage.Suggestion 1.In the youth table tennis training, when popularizing the women's fast force type play, the backhand pull down spin and the upper spin ball technique may take Liu Shiwen's movement technique as the template, will enhance the training efficiency. 2.More biomechanical tests should be carried out on the technical movements of elite athletes, and a template and database of key technical movements should be set up to lay the foundation for the training, monitoring and diagnosis of technical movements of athletes.Liu Shi-wen 's hand pull down spin ball technology shows the characteristics of speed and force, through lower extremity extension, torsion of torso and "whipping" action of upper limb, finally energy is transferred to racket, strength is concentrated, explosive force is strong.Liu Shiwen's backhand pull up spin technique also improves the strength of the ball and needs to improve the ability to control the ball's rotation and curl.In the technique of pulling the ball, Liu Shiwen relaxes the muscles of the upper limbs, moves quickly, and makes full use of the strength of the lower limbs and torso when hitting the ball.
