IMPACTS OF BALANCE TRAINING ON TENNIS PLAYERS’ PERFORMANCE

ABSTRACT Introduction Maintaining body balance is a prerequisite for good tennis practice. Therefore, the demands of technical movements for competitive playability are achieved only after players have improved balance. Objective Analyze the impacts of balance training on the performance of tennis players. Methods 24 male tennis college students, 18 to 21 years old, were selected and divided into experimental and control groups. The intervention took place under a specific balance training protocol for eight weeks, and data were collected in the experimental group before and after the intervention. Results The test time with eyes closed in unipodal support, Romberg test, eyes closed standing, and walking standing in the experimental group was 37.340 ± 14.382s, 67.250 ± 30.275s, 21.070 ± 7.887s and 4.510 ± 0.540s respectively, showing statistical superiority over the control group. Conclusion After eight weeks of balance training exercise intervention, compared with the subjects without instability training exercise intervention, the subjects’ static and dynamic balance ability after eight weeks of training were significantly improved. Level of Evidence II; Therapeutic studies - investigation of treatment outcomes.【摘要】 引言 维持身体平衡是开展优质网球训练的必要前提。唯有运动员的平衡能力得到提升，方能满足竞技赛事对技术动作的竞技性要求。 研究目的 分析平衡训练对网球运动员运动表现的影响。 研究方法 选取24名年龄介于18至21岁的男子高校网球运动员，将其分为实验组与对照组。实验组受试者接受为期8周的特定平衡训练方案干预，并于干预前后采集相关测试数据。 研究结果 实验组受试者在单腿闭眼支撑测试、龙贝格（Romberg）平衡测试、闭眼站立测试以及行进站立测试中的耗时分别为37.340 ± 14.382s、67.250 ± 30.275s、21.070 ± 7.887s及4.510 ± 0.540s，各项指标均显著优于对照组，且具有统计学意义。 研究结论 经8周平衡训练干预后，与未接受稳定性训练干预的受试者相比，实验组受试者的静态与动态平衡能力均得到显著提升。 证据等级II级；治疗性研究——治疗效果评估类研究。
