This study compared the effects of integrative neuromuscular training (INT) versus FIFA 11+ protocols on sprint, change of direction performance and inter-limb asymmetries. Thirty young (U-11) male soccer players (age: 11.2 ± 0.7 years; height: 145.6 ± 6.8 cm; body mass: 72.5 ± 3.0 kg) were randomly assigned to each training group, which consisted of two sessions/week for a period of 6-weeks. The INT consisted of play-based tasks designed according to structured training principles, whereas the FIFA 11+ followed standard procedures. Before and after the intervention, 0-20 sprint time and double 180° change of direction test were measured from which change of direction deficit and inter-limb asymmetries were also computed. Significant improvements were found in double 180° change of direction test and deficit for both legs in both groups (all p < 0.01). A significant decrease was observed in 0-20 sprint time (p < 0.05), and inter-limb asymmetries for FIFA 11+ group. A significant group-by-time effect, which favored the FIFA 11+ group, was observed on double 180° change of direction in right leg (F = 15.08, p < 0.01, η²_p = 0.35), but also in change of direction deficit in right (F = 214.19, p < 0.01, η²_p = 0.88), and left legs (F = 126.79, p < 0.01, η²_p = 0.82). These findings suggest youth soccer practitioners should select the FIFA 11+ program to improve inter-limb asymmetries and 0-20 sprint time, and that both training methods are suitable to improve 180° change of direction performance.

这项研究比较了综合性神经肌肉训练（INT）和FIFA 11+协议对冲刺，方向性能变化和肢间不对称的影响。30名（U-11）年轻的男足球运动员（年龄：11.2±0.7岁；身高：145.6±6.8 cm；体重：72.5±3.0 kg）被随机分配到每个训练组中，每星期进行两次训练6周的时间。廉政局由根据结构化训练原则设计的基于比赛的任务组成，而FIFA 11+则遵循标准程序。在干预之前和之后，测量0-20冲刺时间和180度两次方向变化测试，从中还计算出方向缺陷和肢间不对称性的变化。两组的双腿双转180°方向测试和赤字均得到了显着改善（所有p  <0.01）。 FIFA 11+组的0-20冲刺时间和p -0.05的肢间不对称性显着降低。甲显著组按时间效应，这有利于该FIFA 11+组中，观察到在右腿方向的双180°变化（F = 15.08，p  <0.01，η ² _p  = 0.35），而且在改变在正确的方向赤字（F = 214.19，p  <0.01，η ² _p  = 0.88），和左支腿（F = 126.79，p  <0.01，η ² _p = 0.82）。这些发现表明，青少年足球从业人员应选择FIFA 11+程序以改善肢间不对称性和0-20短跑时间，并且两种训练方法均适合于改善180°方向变化。
