TENNIS PRACTICE EFFECTS ON MALE COLLEGE STUDENTS’ PHYSICAL FUNCTION IN DIFFERENT CLASSES

ABSTRACT Introduction Recent studies corroborate the statement that tennis practice affects the physical health of college students differently, depending on the evolutionary class in this sport. However, it is still necessary to consolidate a theoretical basis for college students to maximize the gain of benefits tennis practice, as a reference for teaching and updated training. Objective Provide a scientific and theoretical background to guide the physical exercise of college students. Methods An experimental study on different periods of tennis exercises in different classes during 16 weeks was carried out on 60 college students. Biological and anthropometric data were collected and statistically analyzed to verify the effects of the interventions. Maximizing results and best sports practices were discussed. Results The relatively long duration of a single exercise in tennis can improve the recovery rate of the cardiovascular response load, achieving greater gain from cardiovascular exercise. After 16 weeks of tennis exercise, both groups’ progression rates significantly improved compared to college students with less practice. Conclusion Tennis exercise can improve lung function and cardiac function in male college students; the improvement in the physical function of students who practice tennis three times a week is significantly higher than male college students who practice tennis once a week. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

摘要
引言
近期研究证实，网球练习对大学生身体健康的影响因该运动的进阶组别存在差异。但目前仍需夯实理论基础，助力大学生最大化获取网球练习的健身收益，为网球教学与训练方案优化提供参考依据。

研究目的
为指导大学生体育运动开展提供科学理论支撑。

研究方法
本研究纳入60名大学生作为受试对象，针对不同组别受试者开展为期16周的差异化网球练习周期实验。研究收集了受试者的生物学指标与人体测量学（anthropometric）数据，并开展统计学分析，以验证干预措施的健身效果；同时对最优训练效果与最佳运动实践方案进行了探讨。

研究结果
单次网球练习时长相对较长可提升心血管反应负荷的恢复速率，从而从心血管训练中获得更大收益。经过16周的网球练习后，相较于练习频次较低的大学生，两组受试者的各项身体机能改善速率均得到显著提升。

研究结论
网球练习可改善男性大学生的肺功能与心功能；每周进行3次网球练习的学生，其身体功能提升水平显著高于每周练习1次的男性大学生。
证据等级：II级；治疗性研究——治疗效果调查。
