EFFECT OF HIGH-INTENSITY INTERVAL TRAINING ON FOOTBALL PLAYERS’ PERFORMANCE

ABSTRACT Introduction High-intensity interval training contributes expressively to physical training and has been gradually applied to the soccer field. This sport has received more attention in colleges and universities in the country. However, studies are needed on the most appropriate training methods to improve the players’ ability among college students, increasing the competitive level among athletes. Objective Investigate the influence of high-intensity intermittent training on soccer players’ sports performance. Methods 30 student soccer players were selected at a university for six weeks, and four training sessions were held per week. The experimental group performed intermittent high-intensity training for training; the control group used the traditional aerobic resistance training method. For the experiment, indicator information was collected for integration and analysis before the start of activities and at the end of the six weeks. Results High-intensity intermittent training can improve the fitness index and FMS index of players and also can keep the fluctuation level in players’ performance higher; the range of performance improvement is considerably larger than the traditional aerobic training method. Conclusion High-intensity intermittent training can improve players’ fitness and agility, reduce sports injuries, improve physical reserve, and promote the progress of soccer players’ sports achievements. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.摘要 引言 高强度间歇训练对体能训练的提升作用显著，且已逐步推广至足球运动赛场。足球运动在国内高校中受到了越来越多的重视。然而，当前仍需针对高校足球运动员开展相关研究，以确定最适宜的训练方法，从而提升运动员的竞技能力与整体竞技水平。 研究目的 探究高强度间歇训练对足球运动员运动表现的影响。 研究方法 选取某高校30名学生足球运动员，开展为期六周、每周四次训练的实验。实验组采用高强度间歇训练方案，对照组则沿用传统有氧耐力训练方法。分别于实验启动前与六周训练周期结束后采集相关指标信息，并进行整合分析。 研究结果 高强度间歇训练可有效提升运动员的体能指标与功能性动作筛查（Functional Movement Screen, FMS）评分，同时可维持运动员运动表现的波动水平处于较高区间；其运动表现提升幅度显著优于传统有氧训练方法。 研究结论 高强度间歇训练能够改善足球运动员的体能与敏捷性，降低运动损伤风险，提升身体储备能力，并助力运动员运动成绩的提升。 证据等级为II级；属于治疗性研究——治疗效果探究类研究。
