Forty-five per cent lower acute injury incidence but no effect on overuse injury prevalence in youth floorball players (aged 12–17 years) who used an injury prevention exercise programme: two-armed parallel-group cluster randomised controlled trial

Figure 1. Flowchart of clusters (clubs), teams and players throughout the trial. F, female; IPEP, injury prevention exercise programme; M, male.

Figure 2. Sex-adjusted injury incidence per week, based on moving average (moving average week 2=competitive week 1+2; moving average week 3=competitive week 2+3, etc) in the intervention group (black line) and control group (grey line). Values within parentheses on the x axis show the number of weekly player reports for each moving average week observation.

Figure 3. Sex-adjusted weekly injury prevalence in the intervention group: all injuries (black line) and substantial injuries (black dotted line); control group: all injuries (grey line) and substantial injuries (grey dotted line). Values within parentheses on the x axis show the number of weekly player reports for each observation.
