ELBOW JOINT TRAINING IN TABLE TENNIS TEACHING

ABSTRACT Introduction Table tennis is widely acclaimed by the public and is also one of the most popular activities chosen by Chinese athletes. However, many athletes only pay attention to learning sports skills in sports training and neglect muscle strength training. Objective Study the training strategy of the muscles that make up the elbow joint in table tennis players and its influence on sports. Methods This paper selected 5 high-level high school table tennis athletes from a university as research volunteers. The training content included strength training, flexibility training, and other physical tests. The duration of the training was one hour, four times a week. The total training lasted six weeks. Results For the movement at a speed of 180°/s, the peak torque, the relative peak torque, and the percentage of peak flexor and extensor torque of the elbow joint of the athletes showed significant gains. However, the elbow joint change in flexion range was much shorter than in extension. Conclusion Coaches and athletes should choose a mode of elbow muscle training according to their actual needs, promoting the development of elbow muscle strength in athletes to raise their competitive level. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.摘要 引言：乒乓球深受大众青睐，亦是我国运动员最常选择的热门运动项目之一。但诸多运动员在体育训练中仅专注于学习运动技能，却忽视了肌肉力量训练。 研究目的：探讨乒乓球运动员肘关节（elbow joint）相关肌肉的训练策略及其对运动表现的影响。 研究方法：本文选取某高校的5名高水平高中乒乓球运动员作为研究受试者。训练内容涵盖力量训练、柔韧性训练及其他体能测试；训练周期为每周4次，每次1小时，总训练时长共计6周。 研究结果：在180°/s的运动速度下，运动员肘关节的峰值扭矩（peak torque）、相对峰值扭矩（relative peak torque），以及屈肌与伸肌峰值扭矩占比均出现显著提升。但肘关节屈曲活动范围的变化幅度远小于伸展活动范围。 研究结论：教练员与运动员应结合实际需求选择肘关节肌肉训练模式，以促进运动员肘关节肌肉力量发展，进而提升竞技水平。 证据等级II级；治疗性研究——治疗结局调查。
