In this study, we investigated the static balance of adult and adolescent elite soccer players to understand how expertise and playing position influence postural control. Seventy-one national level players were tested using a force platform to acquire Center-of-Pressure (COP) data in uni- and bipedal stance and calculate sway area (SA), COP path length, velocity and displacements. The results show significant differences in postural sway related to age and playing position only for single-limb stance. In particular, midfielders exhibited significantly lower values of SA with respect to defenders (-48%, p = 0.001) and the under-15 players exhibited SA 42-64% higher than all the others (p = 0.001). In the light of planning training or rehabilitation programs specific for each player's role and age, sway measurements may supply useful, objective and reliable information only for the unipedal test as the bipedal standing appears not challenging enough to let differences in balance abilities emerge.
在本研究中，我们调查了成年和青少年精英足球运动员的静态平衡能力，以了解专业水平和比赛位置如何影响姿势控制。使用测力平台对71名国家级运动员进行测试，以获取单脚和双脚站立时的压力中心（COP）数据，并计算摆动面积（SA）、COP路径长度、速度和位移。结果表明，仅在单腿站立时，姿势摆动与年龄和比赛位置存在显著差异。具体而言，中场球员的SA值相对于后卫显著更低（-48%，p = 0.001），15岁以下球员的SA值比其他所有球员高42-64%（p = 0.001）。鉴于为每个球员的角色和年龄制定特定的训练或康复计划，摆动测量可能仅为单脚测试提供有用、客观和可靠的信息，因为双脚站立似乎挑战性不足，无法显现出平衡能力的差异。
