Abstract：
OBJECTIVE: To investigate the effects of neuromuscular training, with minimal or no equipment, on physical performance of youth athletes.
METHODS: Systematic review with meta-analysis.
METHODS: MEDLINE, EMBASE, CENTRAL, CINAHL, PEDro and SportDiscuss from inception to March/2022.
METHODS: youth athletes (15-24years), from Olympic team sports; used neuromuscular training 2-3 times/week for, at least, 6 weeks; had a control group/usual training group; physical performance as outcomes; randomized controlled trial.
RESULTS: Pooled estimate of standardized mean difference (SMD), and 95% confidence interval (95%CI).
RESULTS: Thirty-four studies (1111 participants) were included. Results showed that neuromuscular training improved power (SMD: 0.84 [95%CI: 0.58, 1.10]; n = 805; I2 = 64%), speed (SMD: -1.12 [95%CI: -1.68, -0.57]; n = 688; I2 = 90%) and agility (SMD: -1.21 [95%CI: -1.60, -0.83]; n = 571; I2 = 76%) compared to control group, but showed no difference between groups for muscle strength (Quadriceps SMD: 0.34 [95%CI: -0.02, 0.69]; n = 132; I2 = 0%, Hamstrings: SMD: 0.64 [95%CI: -0.04, 1.33]; n = 132; I2 = 71%), balance and flexibility.
CONCLUSIONS: Clinically, neuromuscular training with minimal equipment may be useful for teams with limited resources to improve mainly athletes\' power and agility, including those interventions that were designed to injury prevention. Future high-quality studies are likely to change these estimates.

摘要：
目的：研究神经肌肉训练的效果，设备很少或没有，关于青少年运动员的身体表现。
方法：系统评价与荟萃分析。
方法：MEDLINE，EMBASE,中部,CINAHL,PEDro和SportDiscuss从成立到2022年3月。
方法：青年运动员（15-24岁），来自奥林匹克团体运动；每周使用神经肌肉训练2-3次，至少,6周；有对照组/常规训练组；身体表现作为结果；随机对照试验。
结果：标准化均差（SMD）的汇总估计，和95%置信区间(95CI)。
结果：纳入34项研究（1111名参与者）。结果显示，神经肌肉训练改善力量（SMD：0.84[95CI：0.58，1.10];n=805;I2=64％），速度(SMD:-1.12[95CI:-1.68,-0.57];n=688;I2=90%)和敏捷性(SMD:-1.21[95CI:-1.60,-0.83];n=571;I2=76%)与对照组相比,但两组之间的肌肉力量没有差异(股四头肌SMD:0.34[95CI:-0.02,0.69];n=132;I2=0%,腿筋：SMD：0.64[95CI：-0.04，1.33]；n=132；I2=71％），平衡和灵活性。
结论：临床上，用最少的设备进行神经肌肉训练可能对资源有限的团队有用，主要提高运动员的力量和敏捷性，包括那些旨在预防伤害的干预措施。未来的高质量研究可能会改变这些估计。
