Calculations of the Dimensions of the RE-AIM Framework

RE-AIM	Numerator	Denominator
Reach, %
Setting level	Eligible teams in IG	Randomized IG teams
Individual level	Eligible athletes in IG	Athletes on randomized IG teams
Representativeness	Eligible teams in IG	Teams playing at described competition levels (Flanders, Belgium)
Effectiveness (injury incidence density and hazard ratio)
Setting level	Difference in lower extremity injury risk per 1000 exposure hours between the IG and control group
Adoption, %
Setting level	Teams approached that agreed to participate and implement the program	Eligible teams
Implementation
Setting level	Coaches who successfully implemented key program elements	Coaches of randomized IG teams
Individual level	Program sessions followed by athletes of randomized IG teams	Program sessions that ideally needed to be followed by randomized IG teams
Adherence	Program sessions followed by IG athletes who eventually implemented the program	Program sessions that ideally needed to be followed by IG teams that eventually implemented the program
Maintenance	Proportion of coaches who planned to continue the intervention program in future seasons

Abbreviations: IG, intervention group; RE-AIM, reach, effectiveness, adoption, implementation, maintenance.
