: Improper neuromuscular control with excessive dynamic valgus loading of the knee has been identified as one of the main anterior cruciate ligament injury risk factors. This study aimed to analyze the impact of the FIFA 11+ training program on the valgus loading of the knee in academy soccer players over a competitive season. : A prospective study was conducted on 85 players. The drop vertical jump test was carried out before the match and at the end of the same match at the beginning and at the end of the season over a period of 11 months. : An increase of the varus angle on the right limb was noted between the start and the end of the season at the beginning of the match (-4.7 ± 8.9 versus -6.9 ± 6, = 0.003) and between the start and the end of the match in values measured at the beginning of the season (-4.7 ± 8.9 versus -7.7 ± 9, < 0.001). An increase of the flexion angle of both limbs was noted between the start and the end of the season in values measured at the start of the match (left limb 76.8 ± 32.8 versus 98.6 ± 17.2, < 0.001; right limb 76.4 ± 32.8 versus 96.1 ± 16.1, < 0.001) and between the start and the end of the season in values measured at the end of the match (left limb 92.8 ± 19.1 versus 98.5 ± 16.3, = 0.002; right limb 92.6 ± 19.2 versus 96.7 ± 14.5, = 0.013). : A decrease in dynamic valgus angle and an increase in knee flexion angle measured with the DVJ test were noted between the start and the end of the season, suggesting a protective role of the FIFA 11+ training program.
膝关节过度动态外翻负荷导致的神经肌肉控制不当已被确定为前交叉韧带损伤的主要危险因素之一。本研究旨在分析国际足联11+训练计划对青少年足球运动员在一个赛季中膝关节外翻负荷的影响。：对85名运动员进行了一项前瞻性研究。在11个月的赛季开始和结束时，在比赛前和同一场比赛结束时进行了垂直跳测试。：在赛季开始时比赛开始和结束之间，右下肢内翻角度增加（-4.7±8.9对-6.9±6，P = 0.003），在赛季开始时比赛开始和结束时测量的值之间也增加（-4.7±8.9对-7.7±9，P < 0.001）。在赛季开始和结束之间，在比赛开始时测量的值中，双下肢屈曲角度增加（左下肢76.8±32.8对98.6±17.2，P < 0.001；右下肢76.4±32.8对96.1±16.1，P < 0.001），在赛季开始和结束之间，在比赛结束时测量的值中也增加（左下肢92.8±19.1对98.5±16.3，P = 0.002；右下肢92.6±19.2对96.7±14.5，P = 0.013）。：在赛季开始和结束之间，通过DVJ测试测量的动态外翻角度减小，膝关节屈曲角度增加，这表明国际足联11+训练计划具有保护作用。
