Context : Hamstring strain injury (HSI) is the most prevalent in football (soccer), and a few intrinsic factors have been associated with higher rates. Objective To describe prevalence of main risk for HSI professional under-20 players. Design Cross-sectional study. Setting Physiotherapy laboratory, Federal University Health Sciences Porto Alegre (Brazil). Participants A total 101 players (52 49 players). Intervention An evidence-based testing protocol screening factors. Main Outcome Measures Anamnesis, ultrasonography hamstrings, passive straight-leg raise test, Functional Movement Screen, isokinetic dynamometry were performed. Eleven each leg assessed, besides player’s age as systemic factor. Reports delivered to coaching staff. Results Professionals had greater history compared (40% vs 18%). No between-group differences found other tests. Altogether, 30% already sustained at least one HSI; 58% injuries adjacent regions; 49% short biceps femoris fascicles; 66% 21% poor active flexibility, respectively; 42% 29% deficits functional movements core stability, 7% 26% presented bilateral imbalance hamstring concentric eccentric strength, 87% 94% obtained low values hamstring-to-quadriceps conventional ratios, respectively. Two-thirds 3 5 per leg. None was fully free Conclusion Most present multiple sustaining an HSI. weakness factor, but teams should also be aware movements, fascicle length.
