Background

The bulk of relevant studies compare individual or very few sports and on small samples of athletes. This requires extensive analysing postural stability in various sports.

Research question

The main objective of our study was to identify the features of postural stability in a normal vertical stance in athletes of various kinds.

Methods

This study compares postural stability in a normal bipedal stance with eyes open (EO) and eyes closed (EC) conditions among athletes (n = 936, age: 6–47 years) from different sports and performance level. Postural stability was measured through the center of pressure (COP) sway area (AS) and velocity (VCP) while standing quietly in a normal bipedal position with EO and EC on a stabiloplatform (50 Hz).

Results

The order of VCP-EO increase in athletes compared to Control was as follows: Shooting (-11.3 %, p < .0001) < Football (-10.4 %, p < .0001) < Boxing (-8.7 %, p < .0001) < Cross-Country Skiing (-7.2 %, p < .0001) < Gymnastics (-7.0 %, p < .0001) < Running (-6.9 %, p < .0001) < Team Games Played with Hands (-6.8 %, p < .0001) < Wrestling (-6.3 %, p < .0001) < Tennis (-5.5 %, p = .0004) < Alpine Skiing (-5.4 %, p = .002) < Rowing (-5.0 %, p = .194) < Speed Skating (-4.7 %, p = .004) < Figure Skating (-3.6 %, p = .034) < Control.

Significance

Practicing any kind of sport was associated with increased postural stability in normal bipedal stance. This is the first study that provides reference values of COP sway and velocity with and without visual control on a stable force platform for different sport groups.

运动员姿势稳定性：运动指导的作用

背景

大部分相关研究比较了个别或极少数运动以及小样本运动员。这需要广泛分析各种运动中的姿势稳定性。

研究问题

我们研究的主要目的是确定各种运动员在正常垂直站姿下的姿势稳定性特征。

方法

本研究比较了不同运动和表现水平的运动员（n = 936，年龄：6-47 岁）在睁眼 (EO) 和闭眼 (EC) 条件下正常双足站立时的姿势稳定性。通过压力中心 (COP) 摇摆区 (AS) 和速度 (VCP) 测量姿势稳定性，同时安静地站在正常双足位置，EO 和 EC 位于稳定平台 (50 Hz) 上。

结果

与对照组相比，运动员 VCP-EO 增加的顺序如下：射击 (-11.3 %, p < .0001) < 足球 (-10.4 %, p < .0001) < 拳击 (-8.7 %, p < .0001) ) < 越野滑雪 (-7.2 %, p < .0001) < 体操 (-7.0 %, p < .0001) < 跑步 (-6.9 %, p < .0001) < 用手玩的团队游戏 (-6.8 %) , p < .0001) < 摔跤 (-6.3 %, p < .0001) < 网球 (-5.5 %, p = .0004) < 高山滑雪 (-5.4 %, p = .002) < 赛艇 (-5.0 %, p = .194) < 速度滑冰 (-4.7 %, p = .004) < 花样滑冰 (-3.6 %, p = .034) < 对照。
