Description
Summary:Background and ObjectiveHamstring Strain Injuries (HSI) are increasingly common in football players. Ultrasound screening assesses muscle predispositions linked to HSI risk. This study aims to identify ultrasound-measurable risk factors for HSI prediction.Study Design and ParticipantsWe targeted 56 legs of 28 Japanese professional footballers, mean age 24.6±2.4 years. Fascicle length corrected with femur length, pennation angle (PA) and muscle stiffness of the biceps femoris long head (BFlh) were measured using ultrasound elastography before the 2022 season where new HSI occurrences were prospectively observed.Risk Assessment and Main OutcomesThe dependent variable was HSI occurrence, with putative risk factors being ultrasound-defined anatomical predispositions. Statistical analysis used SPSS version 28 with a 5% significance level.ResultsDuring the 2022 season, 8 new HSIs occurred. BFlh stiffness was significantly higher in the HSI group (30.53±3.38 kPa) than the non-HSI group (22.49±6.21, p
