FIFA11+ Kids is a warm-up program specially designed to prevent football injuries in children. This systematic review and meta-analysis aimed to summarize the effects of FIFA11+ Kids on injury prevention in young football players. PubMed, Web of Science, Embase, Cochrane Library, and China National Knowledge Infrastructure were searched from 1 January 2016 to 24 August 2022. The primary outcome was overall injuries, and the secondary outcomes were severe, ankle, knee, and lower extremity injuries. Risk ratios (RRs) were calculated for each outcome. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. A total of 230 articles were screened, 6 of which were finally included in the meta-analysis. Compared with normal warm-up training, FIFA11+ Kids significantly reduced overall injury risk (RR = 0.52 [95% CI, 0.44–0.62]; p < 0.00001), severe injury risk (RR = 0.33 [95% CI, 0.18–0.61]; p = 0.0004), lower extremity injury risk (RR = 0.51 [95% CI, 0.41–0.65]; p < 0.00001), knee injury risk (RR = 0.45 [95% CI, 0.29–0.72]; p = 0.0009), and ankle injury risk (RR = 0.56 [95% CI, 0.35–0.89]; p = 0.01) in young football players. FIFA11+ Kids was found to be an effective approach to decrease the injury risk among young football players, which is worth generalizing extensively.
