To describe the perceptions of physiotherapists and the injury prevention practices implemented within elite women's football clubs in Brazil. Cross-sectional study. Online survey. Head physiotherapists from 32 Brazilian elite clubs. Structured questionnaire. Physiotherapists identified ACL rupture as the primary target for prevention. The top-five perceived injury risk factors included ‘early return to sport after injury’, ‘workload too high’, ‘previous injury’, ‘poor sleep/rest’, and ‘muscle strength/power deficit’. ‘Adoption of return to sport criteria’ was almost unanimously recognized as a very important preventive strategy. ‘Poor infrastructure’ was elected as the main barrier to implementing prevention programs. From a practical standpoint, at least two-third of clubs implemented multi-component exercise interventions for injury prevention. These interventions typically encompassed flexibility/mobility, balance/proprioception, lumbo-pelvic stability, and agility exercises, alongside exposure to sprinting. Strength training routines typically included traditional, functional, and eccentric exercises. Most teams also employed other prevention strategies, including adoption of return to sport criteria, internal workload monitoring, post-exercise recovery modalities, preseason risk factor screening, and application of rigid strapping tapes. This study provided unprecedented insights into the physiotherapists' perceptions and injury prevention practices implemented within elite women's football clubs. •ACL rupture is recognized as the primary target for prevention.•‘Adoption of return to sport criteria’ is perceived as a key preventive strategy.•Clubs employ multi-component exercises for injury prevention.•Preventive exercises are both team-wide and personalized by physiotherapists.

Purpose The purpose of this study was to assess if differences in hamstring strength, hamstring-to-quadriceps (H:Q) strength ratio, and biceps femoris long head (BF LH ) fascicle length exist between male and female professional football (soccer) players. Methods One-hundred professional footballers participated in this cross-sectional study: 50 men and 50 women. Ultrasound images of BF LH muscle and isokinetic dynamometry tests were performed. Results Men were stronger than women for hamstring concentric (2.01 ± 0.21 Nm/kg vs. 1.55 ± 0.23 Nm/kg; p  < 0.001; large effect size, 2.08) and eccentric (2.87 ± 0.45 Nm/kg vs. 2.39 ± 0.32 Nm/kg; p  < 0.001; large effect size, 1.23) peak torques. There was no sex-related difference for H:Q conventional ratio (concentric/concentric; 0.55 ± 0.06 vs. 0.55 ± 0.07); but women presented greater H:Q functional ratio (eccentric/concentric; 0.78 ± 0.12 vs. 0.85 ± 0.09; p  = 0.003; moderate effect size, 0.66). Men and women presented similar BF LH fascicle length: 0.24 ± 0.05 vs. 0.23 ± 0.05 (values normalized by muscle length). Conclusions Among the muscular factors assessed in this study, men presented stronger hamstring muscles, women presented greater H:Q functional ratio, and there was no sex-related differences for H:Q conventional ratio or BF LH fascicle length.
