FATIGUE INJURY IN VOLLEYBALL PLAYERS UNDER JUMP RESISTANCE TRAINING

ABSTRACT Introduction The rapid development of competitive sports in the world requires volleyball players not just sufficient physical fitness but also the ability to understand and learn advanced techniques and tactics. In response to the increasing pace of competitive sports, research on fatigue injuries in volleyball players must be deepened and expanded, making coaches and players aware of sports injuries and their means of prevention. Objective Explore the fatigue injury characteristics in volleyball players under jump resistance training. Methods 157 volleyball players from eight sports colleges were selected as the research subject. Composed of 94 male volleyball players and 63 female volleyball players. Results In the investigation of the 157 volleyball players, 153 had some degree of injury, representing a total of 97.1% of the players, and only four non-injured, representing 1.80%; 95 people were injured in special technical training (61.20%); 43 were injured in advanced training (27.62%); 17 people were injured in preparatory activities (10.86%). No one was injured during relaxation activities. Conclusion Preventive measures for fatigue injuries in volleyball players include strengthening with medical supervision and balanced exercise load distribution. With attention to rational preparation of activities including strengthening and knee joint flexibility. Evidence level II; Therapeutic Studies - Investigating the results.摘要 引言 全球竞技体育的飞速发展，对排球运动员提出了更高要求——不仅需要具备充足的身体素质，更需掌握并学习先进的技战术。为应对竞技体育日益加快的赛事节奏，针对排球运动员疲劳性损伤的研究必须进一步深化与拓展，以此帮助教练员与运动员充分认识运动损伤及其预防手段。 研究目的 探讨抗跳跃训练模式下排球运动员的疲劳性损伤特征。 研究方法 选取8所体育院校的157名排球运动员作为研究对象，其中男性排球运动员94名，女性排球运动员63名。 研究结果 在对157名排球运动员的调研中，153人存在不同程度的损伤，占总人数的97.1%；仅4人未出现损伤，占比1.80%。其中，专项技术训练阶段受伤人数为95人，占比61.20%；进阶训练阶段受伤人数为43人，占比27.62%；准备活动阶段受伤人数为17人，占比10.86%；放松活动阶段无人员受伤。 研究结论 排球运动员疲劳性损伤的预防措施包括：在医疗监督下强化训练，合理分配运动负荷；同时需重视准备活动的合理性，加强相关训练并提升膝关节柔韧性。 证据等级：Ⅱ级；治疗性研究——结果探究类。
