This randomized controlled trial evaluated whether an eight-week, supervised FIFA 11+ neuromuscular warm-up program improves multifactorial injury risk classification, functional performance, and time-loss injury incidence in youth amateur male soccer players aged 15 to 18 years.
Forty-four players from a regional amateur league were randomly allocated to either the FIFA 11+ group or a control group that continued its routine pre-training warm-up. Injury risk was classified using the Move2Perform algorithm, which integrates demographic data, injury history, the Functional Movement Screen (FMS), and the Lower Quarter Y-Balance Test (YBT-LQ). Jump performance and isometric lower extremity strength were also assessed at baseline and after eight weeks. Time-loss injuries were recorded prospectively throughout the intervention period.
This study was registered retrospectively.
Inclusion Criteria:
Exclusion Criteria:
Investigators who administered the Functional Movement Screen, Lower Quarter Y-Balance Test, jump tests, and strength assessments at baseline and post-intervention were blinded to group allocation. Due to the nature of the intervention, participants and the supervising physiotherapist could not be blinded. Data were de-identified prior to statistical analysis.
Participants performed the complete FIFA 11+ neuromuscular warm-up program three times per week for eight weeks prior to regular training, each session lasting approximately 20 minutes, under the supervision of a certified physiotherapist.
Participants continued their routine pre-training warm-up over the same eight-week period, with no additional structured neuromuscular component.
