Effectiveness of the FIFA 11+ Referees Injury Prevention Program in reducing injury rates in male amateur soccer referees.

Abstract

The Fédération International de Football Association (FIFA) 11+ Referees Injury Prevention Program (FIFA 11+ Referees Program) is a structured warm-up program specially designed to prevent injuries in soccer referees. However, its effectiveness has yet to be fully documented in the literature. Therefore, the purpose of this study was to investigate the effectiveness of the FIFA 11+ Referees Program in reducing injury rates among soccer referees. A randomized controlled trial was conducted. Two hundred male amateur soccer referees (mean±SD age, 31.6±4.1years) participated in this study. Participants were randomly allocated to the experimental and control groups. The experimental group performed the FIFA 11+ Referees Program as a warm-up during training sessions at least twice a week, and the control group performed their usual warm-ups. The participants were followed up for one season. The outcome measures were the incidence of overall injury, initial injury, recurrent injury, injury mechanism, and injury severity (primary), and the rate of adherence to the intervention program (secondary). A total of 24 injuries were reported among 100 referees in the control group in 16606h of exposure (1.45 injuries/1000exposure h), and a total of nine injuries were reported across 100 referees within the experimental group in 17834exposure h (0.50 injuries/1000exposure h). The Injury Risk Ratio (IRR) was 0.35 (95% CI 0.26-0.45). The results indicated that the FIFA 11+ Referees Program effectively reduced injuries in the experimental group by 65% compared to the control group.
