The purpose of the present study was to investigate the effect of a tennis training session on the balance performance of young tennis players. The study was conducted on 36 elite tennis players (age 14 +/- 2 years; body mass 55 +/- 6 kg; body height 165 +/- 6 cm; mean +/- SD) participating in the national young tennis championship. Balance performance was assessed before and immediately after a tennis training session (pre-training and post-training, respectively). The balance assessment was performed with 2 different balance boards and the Biodex Stability System. In addition, dynamometric measurements of peak isokinetic moment in the knee flexors and extensors were performed pre and post tennis training session, to quantify the degree of muscle fatigue induced by the tennis training session. One-way analysis of variance with repeated measures was used to test for differences in balance performance and in isokinetic performance between pre and post tennis training session. The data analysis revealed no significant differences (p > 0.05) in balance performance, whereas there were significant differences in knee joint moment production between pre and post tennis training measures. Although the tennis training session of the present study had no significant effect (p > 0.05) on any of the balance performance indicators examined, there was a decline in balance performance, which suggests that different level of fatigue for an extended period (games) will have greater effect on balance performance. It is suggested that a tennis-specific balance exercise program should be included in the tennis training session.
本研究的目的是探讨网球训练对年轻网球运动员平衡表现的影响。研究对象为参加全国青少年网球锦标赛的 36 名精英网球运动员（年龄 14 ± 2 岁；体重 55 ± 6 公斤；身高 165 ± 6 厘米；平均值 ± 标准差）。平衡表现分别在网球训练前（pre-training）和训练后（post-training）进行评估。平衡评估使用了 2 种不同的平衡板和 Biodex 稳定性系统进行。此外，在网球训练前和后还进行了膝关节等速屈伸力矩的测力测量，以量化网球训练引起的肌肉疲劳程度。采用重复测量的单因素方差分析来测试网球训练前后平衡表现和等速表现的差异。数据分析显示，平衡表现没有显著差异（p > 0.05），而膝关节力矩产生在网球训练前后有显著差异。尽管本研究中的网球训练对所检查的任何平衡表现指标都没有显著影响（p > 0.05），但平衡表现确实有所下降，这表明在较长时间（比赛）内，不同程度的疲劳会对平衡表现产生更大的影响。因此，建议在网球训练中纳入专门的平衡练习计划。
