To assess the existence of correlations between static and dynamic balance abilities in young and professional elite soccer players.
Cross-sectional.
Fifty-one elite players who regularly compete at national level divided into two groups: Professional (age 18-34, n = 20) and Under 15-17 (age 14-16, n = 31).
Dynamic balance was assessed for the case of a single-leg landing task by means of vertical time to stabilization (TTS) and postural sway calculated on the basis of center-of-pressure (COP) trajectories (sway area, COP displacements in antero-posterior and medio-lateral direction, COP path length). The same parameters were also measured for a 20 s one-legged stance to assess static balance abilities.
No significant correlations were found between static and dynamic balance parameters except for TTS and COP displacements in the antero-posterior direction (r = 0.29, p = 0.003). Professional players are characterized by lower TTS in comparison with youth leagues players (0.767 vs. 1.188 s for the dominant limb, p < 0.001) and exhibit reduced sway area (of 34-40%, p < 0.05) for both conditions tested.
The assessment of balance in soccer players should be performed with both dynamic and static tests, considering that the postural control performances in the two cases are not related.
评估年轻和职业精英足球运动员静态与动态平衡能力之间的相关性。
横断面研究。
51名经常参加国家级比赛的精英球员，分为两组：职业组（年龄18 - 34岁，n = 20）和15 - 17岁以下组（年龄14 - 16岁，n = 31）。
通过单腿落地任务的垂直稳定时间（TTS）以及基于压力中心（COP）轨迹计算的姿势摆动（摆动面积、COP在前后和内外侧方向的位移、COP路径长度）来评估动态平衡。还测量了20秒单腿站立时的相同参数以评估静态平衡能力。
除了TTS与COP在前后方向的位移之间存在显著相关性（r = 0.29，p = 0.003）外，未发现静态和动态平衡参数之间存在显著相关性。职业球员的特点是与青年联赛球员相比TTS更低（优势腿分别为0.767秒和1.188秒，p < 0.001），并且在两种测试条件下摆动面积均减小（34 - 40%，p < 0.05）。
考虑到两种情况下的姿势控制表现不相关，对足球运动员平衡能力的评估应同时进行动态和静态测试。
