Despite the success of the FIFA 11+ programme in preventing injury, convincing coaches and players to do these exercises is diffi cult only in order to prevent injury, unless the programme can be shown to have a positive and direct impact on the performance. Th is study aims to investigate the eff ect of the FIFA 11+ programme on vertical jump performance in male elite-youth soccer players. Twenty-four male soccer players (mean ± SD: age = 16.79 ± 1.18 years, height = 174.17 ± 8.12 cm, mass = 62.45 ± 10.01 kg, experience = 6.96 ± 1.26 years) participated in this study and were randomly divided equally into two groups, FIFA 11+ and control. Th e experimental group performed the FIFA 11+ programme three times per week for eight weeks whereas the control group just performed their regular warm-up programme. Th e mixed-repeated measures ANOVA showed that there was a signifi cant improvement in the vertical jump performance between groups in post-test (P=0.002) while no signifi cant improvement was found between groups aft er 1-month of stopping the FIFA 11+ programme (P=0.076). It can be concluded that performing the eight-week FIFA 11+ programme can enhance the jump height in male elite youth soccer players. It seems that the FIFA 11+ programme could be incorporated into regular soccer practice as a warm-up programme instead of a conventional warm-up programme. However, due to the failure to maintain the long-term eff ectiveness of the FIFA 11+ programme on the jump height of soccer players, the continuation of performing this programme is necessary.

FIFA 11+计划对优秀男子青年足球运动员垂直跳高表现的影响

尽管FIFA 11+计划在预防伤害方面取得了成功，但是说服教练和运动员进行这些练习仅是为了防止伤害是困难的，除非可以证明该计划对成绩有积极的直接影响。本研究旨在调查FIFA 11+计划对男性青少年足球运动员垂直跳高表现的影响。二十四名男性足球运动员（平均年龄±SD：年龄= 16.79±1.18岁，身高= 174.17±8.12厘米，体重= 62.45±10.01公斤，经验= 6.96±1.26岁）参加了这项研究，并随机分为两部分组，FIFA 11+和对照组。实验组每周执行三次FIFA 11+程序，共进行八周，而对照组仅执行常规的预热程序。混合重复测量的方差分析表明，在测试后的1个月后，各组之间的垂直跳跃表现有显着改善（P = 0.002），而各组之间没有发现显着改善11 +程序（P = 0.076）。可以得出结论，执行为期八周的FIFA 11+计划可以提高男性优秀青年足球运动员的跳高。看来FIFA 11+计划可以作为一种热身计划而不是常规的热身计划纳入常规的足球练习中。但是，由于未能维持FIFA 11+程序对足球运动员跳高的长期效果，因此有必要继续执行该程序。
