INFLUENCE OF PROGRESSIVE UPPER LIMB STRENGTH TRAINING ON TABLE TENNIS ATHLETES

ABSTRACT Introduction Progressive strength training can help athletes improve their strength levels quickly and safely. By controlling the frequency and amplitude of vibrations, muscles can produce unconscious and voluntary contractions that help prevent diseases such as osteoporosis. Objective To explore the change in sports performance caused by progressive upper limb muscle strength training in table tennis players. Methods 12 table tennis players with a minimum experience of 5 years were randomly divided into experimental and control groups. The control performed traditional strength training methods while the experimental group used the progressive directed strength training method developed by the research team for nine weeks. Tests were performed on ISOMED 2000 equipment at the conditions of 60°/s and 450°/s. Results Circumference, muscle strength, and relative upper limb strength increased. In addition, a difference in the rate of the maximum elbow flexion moment of the athletes in the experimental group in the 60°/s test conditions was observed. At 450°/s, the maximum flexion and extension elbow moment showed a significant difference (P&lt;0.05). Conclusion The progressive strength training method significantly affects the athletes’ maximum elbow flexion moment and maximum elbow extension moment than traditional strength training methods. Muscle strength progress was noted mainly in the elbow and wrist joints, with less intensity in the shoulders. Evidence Level II; Therapeutic Studies – Investigating the results.摘要 引言：渐进式力量训练可帮助运动员快速且安全地提升力量水平。通过调控振动的频率与幅度，肌肉可产生无意识及自主收缩，有助于预防骨质疏松等疾病。 研究目的：探究渐进式上肢肌肉力量训练对乒乓球运动员运动表现的影响。 研究方法：将12名至少拥有5年运动经验的乒乓球运动员随机分为实验组与对照组。对照组采用传统力量训练方案，实验组则使用本研究团队开发的渐进式定向力量训练方案，训练周期为9周。测试在ISOMED 2000设备上完成，测试角速度分别设置为60°/s与450°/s。 研究结果：受试者的上肢围度、肌肉力量及相对上肢力量均有所提升。此外，实验组运动员在60°/s测试条件下的最大肘关节屈曲力矩速率存在差异；在450°/s条件下，肘关节最大屈曲与伸展力矩均存在显著性差异（P<0.05）。 研究结论：相较于传统力量训练方案，渐进式力量训练方案对运动员的最大肘关节屈曲力矩与最大肘关节伸展力矩具有显著影响。肌肉力量提升主要集中于肘关节与腕关节，肩部力量提升幅度较小。证据等级II级；治疗性研究——结果探究类。
