Supplementary Material for: Effects of Yoga Training Applied with Telerehabilitation on Core Stabilization and Physical Fitness in Junior Tennis Players: A Randomized Controlled Trial

Introduction: This study aimed to investigate the effects of yoga training applied with telerehabilitation on core stability, and strength, balance, flexibility, upper extremity stability, body awareness, and quality of life in tennis players aged 6-18 years.
Methods: Forty tennis players were randomly divided into two groups to participate in this study. The control group (n=20) continued tennis training and was informed about the importance of the core region. The yoga group (n=20) received yoga training with telerehabilitation 2 days a week for 8 weeks. Athletes were evaluated with sport-specific core muscle strength and stability tests, the back scratch test, the sit and reach test, the flamingo balance test, the y-balance test (lower quarter), the upper extremity closed kinetic chain stability test, the SF-36, and body awareness questionnaires. Measurements have been done in the tennis club before and after the 8 weeks of training.
Results: A significant increase was determined in core strength and stability, sit and reach, back scratch test, upper extremity stability, and body awareness questionnaire in the yoga group (p<0.001). Flamingo, and Y balance test results were significant (p<0.002). Positive improvements were found in SF-36's energy-fatigue level, mental well-being, social function (p<0.042), pain (p<0.005), and general health (p<0.001). A significant increase was observed in the core strength measurement mean score in the control group (p<0.018). Sit and reach test, flamingo test, and body awareness questionnaire were found to be significant after the application (p<0.001). Significant improvements were found in the pain (p<0.042), and mental well-being (p<0.001) sub-parameters of the SF-36.
Discussion/Conclusion: In the study, it was concluded that yoga training applied with telerehabilitation in tennis players aged 6–18 has a positive effect on core strength, and stabilization, physical fitness parameters, quality of life, and body awareness.

引言：本研究旨在探究远程康复（telerehabilitation）辅助瑜伽训练对6至18岁网球运动员的核心稳定性、核心力量、平衡能力、柔韧性、上肢稳定性、身体意识及生活质量的影响。
方法：本研究共纳入40名网球运动员，采用随机分组法分为两组。对照组（n=20）维持常规网球训练，并接受核心区域重要性的健康宣教；瑜伽组（n=20）每周接受2次远程康复辅助瑜伽训练，持续8周。所有运动员均采用专项核心肌肉力量与稳定性测试、背抓测试（back scratch test）、坐位体前屈测试、火烈鸟平衡测试（flamingo balance test）、下肢Y平衡测试（y-balance test, lower quarter）、上肢闭链稳定性测试、简明健康调查问卷（SF-36）及身体意识问卷进行评估。于8周训练前后，在网球俱乐部内完成所有测量环节。
结果：瑜伽组的核心力量与稳定性、坐位体前屈、背抓测试、上肢稳定性及身体意识问卷得分均显著提升（p<0.001）；火烈鸟平衡测试与下肢Y平衡测试结果同样具有统计学意义（p<0.002）。SF-36量表的能量-疲劳维度、心理幸福感、社会功能（p<0.042）、疼痛维度（p<0.005）及总体健康状况（p<0.001）均得到显著改善。对照组的核心力量测量平均得分亦显著提升（p<0.018）；训练后，对照组的坐位体前屈测试、火烈鸟平衡测试及身体意识问卷得分均出现显著变化（p<0.001）；SF-36量表的疼痛维度（p<0.042）与心理幸福感维度（p<0.001）同样存在显著改善。
讨论/结论：本研究最终得出结论，针对6至18岁网球运动员开展的远程康复辅助瑜伽训练，对其核心力量与稳定性、体适能参数、生活质量及身体意识均具有积极影响。
