The aim of this study was to investigate the effect of young tennis players' expertise on their postural balance (PB) under sensorial conditions with eyes open (EO) and with eyes closed (EC). Our participants were 75 healthy adolescents aged 15-18 years, divided into three groups based on their skill levels: (a) national tennis players (NAT; = 25), regional tennis players (REG; =25), and a control group of non-sport practitioners (CG; = 25). We recorded center of pressure area and mean velocity on a force platform while participants stood in bipedal and unipedal stances in EO and EC conditions for all three groups. Statistical analyses showed that NAT participants swayed less than CG participants in all conditions and less than REG participants in the bipedal stance with EC and in the unipedal stance, both with EO and EC. Thus, tennis practice/experience may have improved PB in this sample, as high-level tennis players had better PB compared to novices, especially in challenging conditions.
本研究旨在探究青少年网球运动员专长对其姿势平衡（PB）的影响，研究分别在睁眼（EO）和闭眼（EC）条件下的感觉条件下进行。参与者为 75 名 15-18 岁健康青少年，根据技能水平分为三组：（a）国家网球运动员（NAT；n=25），区域网球运动员（REG；n=25）和非运动从业者对照组（CG；n=25）。我们记录参与者在 EO 和 EC 条件下双足和单足站立时，在力台上的压力中心面积和平均速度。统计分析表明，在所有条件下，NAT 参与者的晃动均小于 CG 参与者，在 EC 条件下的双足站立和 EO 和 EC 条件下的单足站立时，NAT 参与者的晃动均小于 REG 参与者。因此，网球练习/经验可能改善了该样本的 PB，因为高水平网球运动员的 PB 优于新手，尤其是在具有挑战性的条件下。
