This study aimed to investigate the effects of the 8-week FIFA 11+ Kids program on kinematic risk factors for ACL injury in preadolescent female soccer players during single-leg drop landing. For this, 36 preadolescent female soccer players (10-12 years old) were randomly allocated to the FIFA 11+ Kids program and control groups (18 players per group). The intervention group performed the FIFA 11+ Kids warm-up program twice per week for 8 weeks, while the control group continued with regular warm-up. Trunk, hip, and knee peak angles (from initial ground contact to peak knee flexion) were collected during the single-leg drop landing using a 3D motion capture system. A repeated measure ANOVA was used to analyze groups over time. Significant group × time interactions were found for the peak knee flexion, with a medium effect size ( = 0.05; effect size = 0.11), and peak hip internal rotation angles, with a large effect size ( < 0.01; effect size = 0.28). We found that the FIFA 11+ Kids program was effective in improving knee flexion and hip internal rotation, likely resulting in reducing ACL stress during single-leg drop landing in young soccer players.
本研究旨在调查为期8周的国际足联11 +儿童计划对青春期前女足运动员单腿落地时前交叉韧带损伤运动风险因素的影响。为此，36名青春期前女足运动员（10 - 12岁）被随机分为国际足联11 +儿童计划组和对照组（每组18名运动员）。干预组每周进行两次国际足联11 +儿童热身计划，共8周，而对照组继续进行常规热身。使用3D运动捕捉系统在单腿落地过程中收集躯干、髋部和膝部的峰值角度（从初始地面接触到膝关节最大屈曲）。采用重复测量方差分析来分析不同时间的组间差异。发现膝关节最大屈曲角度存在显著的组×时间交互作用，效应量中等（ = 0.05；效应量 = 0.11），髋部最大内旋角度存在显著的组×时间交互作用，效应量较大（ < 0.01；效应量 = 0.28）。我们发现国际足联11 +儿童计划能有效改善膝关节屈曲和髋部内旋，这可能会减少年轻足球运动员单腿落地时前交叉韧带所承受的压力。
