Predictive Models of Hamstring Performance in Adolescent Athletes

This study investigated the relationships between hamstring strength, flexibility, core endurance, jumping performance, single-leg bridge endurance, and knee joint range of motion (ROM) across six sports disciplines, including football, swimming, volleyball, karate, wrestling, and athletics. A total of 249 athletes (144 men, 105 women) aged 10–18 years participated, with a mean BMI of 22,6 kg/m² and an average of 4.9 years of sports experience. Regression analyses revealed sport-specific predictors of performance and injury risk. Dominant hamstring strength and torque were strong predictors of explosive move-ments like squat jumps in football (R²=0.74, p
