This study systematically reviewed scientific literature regarding the effects of the FIFA 11+ intervention on the change of direction (COD) performance in soccer and futsal players. We conducted a keyword search on June 30, 2020, in SPORTDiscus, PubMed, Web of Science, Academic Search Complete, Scopus, CINAHL, and Google Scholar. We performed a meta-analysis to estimate the pooled effect size of FIFA 11+ interventions on COD performance. Sixteen RCTs studies met the eligibility criteria and were included in this review. Compared to the control group, the FIFA 11+ intervention yielded a 0.87 standard deviation (95% CI = 0.52, 1.21; I² = 96.2%) decrease in the time of COD task completion in soccer and futsal players. In addition, there were no differential effects of the FIFA 11+ intervention compared to the control group in COD performance enhancement among age, gender, athletic level, sport, intervention frequency, intervention duration, and measure covariates. In conclusion, the FIFA 11+ intervention is effective in improving the COD performance of soccer and futsal players. Future studies should recruit large representative samples from professional soccer or futsal teams and examine the effectiveness of the FIFA 11+ intervention on the COD performance among population subgroups (e.g., by age and gender). Studies focusing on different COD tests are warranted to deepen the understanding of the FIFA 11+ intervention effects on the COD performance.

这项研究系统地回顾了有关FIFA 11+干预对足球和五人制足球运动员方向变化（COD）性能的影响的科学文献。我们于2020年6月30日在SPORTDiscus，PubMed，Web of Science，Academic Search Complete，Scopus，CINAHL和Google Scholar中进行了关键字搜索。我们进行了荟萃分析，以评估FIFA 11+干预措施对COD性能的综合影响大小。十六项RCT研究符合入选标准，被纳入本评价。与对照组相比，FIFA 11+干预产生了0.87标准偏差（95％CI = 0.52，1.21; I ² = 96.2％）减少了足球和五人制足球运动员的COD任务完成时间。此外，在年龄，性别，运动水平，运动，干预频率，干预持续时间和测量协变量方面，与对照组相比，FIFA 11+干预对COD表现的改善没有差异。总之，FIFA 11+干预可有效提高足球和五人制足球运动员的COD表现。未来的研究应从职业足球或五人制足球队中招募大量具有代表性的样本，并研究FIFA 11+干预对人群亚组中COD表现的有效性（例如，按年龄和性别）。必须进行针对不同COD测试的研究，以加深对FIFA 11+干预对COD性能的影响的了解。
