The FIFA 11+ warm-up program reduced the risk of injury in soccer players by 30%. However, this pattern was not homogeneous throughout the studies because of clinical and methodological differences in the samples.

In the intervention group, 779 (24%) players had injuries, while in the control group, 1,219 (40%) players had injuries. The FIFA 11+ program reduced injuries in soccer players by 30%, with an estimated relative risk of 0.70 (95% confidence interval, 0.52–0.93, p = 0.01). The sample consisted of 6,344 players, comprising 3,307 (52%) in the intervention group and 3,037 (48%) in the control group. Of these, 6 studies were selected, all of which were randomized clinical trials. A search using the keywords “FIFA,” “injury prevention,” and “football” found 183 articles in the PubMed, MEDLINE, LILACS, SciELO, and ScienceDirect databases. This meta-analysis was based on the PRISMA 2015 protocol. The purpose of this study was to evaluate the efficacy of the FIFA 11+ injury prevention program for soccer players. These injuries may be caused by both modifiable and non-modifiable factors, justifying the adoption of an injury prevention program such as the Fédération Internationale de Football Association (FIFA) 11+. However, soccer players have an increased risk of lower limb injury. Soccer is one of the most widely played sports in the world.
