Comparing trunk mobility, hamstring flexibility, and balance in elite adolescent male athletes across sports

Dynamic Q Angle And Core Endurance In Adolescent Athletes With Patellofemoral Pain Syndrome: A Sex-Based Comparative Retrospective Study

Eastern Mediterranean University · NCT07328750

This project will test whether trunk mobility, hamstring flexibility, and functional balance differ between elite male athletes aged 15–17 who compete in different sports.

What this trial studies

This is a cross-sectional, observational, multi-group comparison of elite adolescent male athletes from different sports branches. Participants will undergo standardized biomechanical testing including trunk range of motion measured with a digital inclinometer (flexion, extension, rotation at lumbosacral and thoracolumbar regions), passive straight leg raise for hamstring flexibility, and the normalized Y-Balance Test for dynamic balance. The primary comparison focuses on normalized Y-Balance composite scores across sports, with secondary analyses of trunk mobility, hamstring flexibility, and correlations among these measures. Results aim to identify sport-specific biomechanical patterns that could relate to injury risk or performance adaptations in competitive youth athletes.

Who should consider this trial

Good fit: Ideal candidates are licensed, actively competing male elite athletes aged 15–17 with at least three years of continuous training who can complete all clinical and biomechanical tests and provide parental consent.

Not a fit: Those unlikely to benefit include athletes outside the 15–17 male elite category, athletes with recent acute musculoskeletal injury, chronic lower-extremity or spinal disorders, recent orthopedic surgery, or conditions affecting balance or movement.

Why it matters

Potential benefit: If successful, the findings could help coaches and clinicians tailor training and injury-prevention or rehabilitation programs to sport-specific biomechanical needs of adolescent athletes.

How similar studies have performed: Prior work using the Y-Balance Test and straight leg raise has shown sport-related differences in balance and flexibility, but combining detailed trunk inclinometer measures across multiple elite adolescent sports is relatively less common.
