The Effect of the FIFA 11+ on Injury Prevention and Performance in Football: A Systematic Review with Meta-Analysis

Football is characterized as a contact sport that increases the risk of injury. For the reduction of injuries, health care providers created a warm-up program that is called the FIFA11+. This is a 20 min warm-up program that has the goal of preventing injuries. This literature review investigated the effects of FIFA11+ on injury prevention and performance in football players. A systematic search was performed in three scientific databases (Pubmed, Scopus, and Physiotherapy Evidence Database (PEDro)) and one search engine (Google Scholar) from inception to June 2022. Relevant studies published in the English language were extracted, evaluated, and independently rated for methodological quality (PEDro scale). Overall, 10 randomized controlled trials were analyzed and their outcomes are discussed. Through the analysis of the studies, it was observed that the groups which performed the FIFA 11+ warm-up program had fewer incidents of injuries. In addition, the athletes of these groups increased their performance, especially in balance, proprioception, and strength of hamstrings. After the analysis, the results and limitations of the randomized controlled trials are discussed. Finally, this review suggests the inclusion of the FIFA 11+ in training sessions, and future recommendations are provided for the next trials for the maximization of their reliability.
