About this trial
This cross-sectional observational study aims to compare trunk mobility, lower extremity flexibility, and functional balance performance across different sports branches in adolescent elite male athletes. Trunk mobility will be assessed using a digital inclinometer in flexion, extension, and rotational movements; hamstring flexibility will be evaluated using the Straight Leg Raise test; and functional balance will be measured using the normalized Y-Balance Test. The study seeks to identify sport-specific biomechanical characteristics and potential indicators related to injury risk and performance adaptations in adolescent competitive athletes.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Male adolescent elite athletes aged 15-17 years

Trial population
Elite adolescent male athletes aged 15-17 years from different sports branches (wrestling, sprint, canoe/kayak, and taekwondo). Participants are recruited from sports performance centers and evaluated using standardized trunk mobility, flexibility, and functional balance assessments.

Observational Clinical and Biomechanical Assessment
Other interventionNo intervention is administered in this study. Participants only undergo standardized observational assessments, including trunk mobility measurements using a digital inclinometer, hamstring flexibility testing with the Straight Leg Raise test, and functional balance evaluation using the Y-Balance Test. No therapeutic or experimental procedures are applied.

Trial outcomes
Primary outcomes
1
Y-Balance Test Composite Score (%)
Dynamic functional balance performance assessed using the Y-Balance Test. Composite score is calculated from normalized anterior, posteromedial, and posterolateral reach distances on the dominant limb.
Time frame
Baseline (single assessment at study enrollment)Secondary outcomes
1
Trunk Mobility - Inclinometer Range of Motion (°)
Spinal mobility measured using a digital inclinometer in flexion, extension, and rotation at the lumbosacral and thoracolumbar regions. Values are recorded in degrees on the dominant side.
Time frame
Baseline (single assessment at study enrollment)2
Hamstring Flexibility - Straight Leg Raise Angle (°)
Passive Straight Leg Raise test performed on the dominant lower extremity using a goniometer. The maximum tolerated angle is recorded in degrees.
Time frame
Baseline (single assessment at study enrollment)3
Body Composition (Descriptive Variable)
Body fat percentage
Time frame
Baseline (single assessment at study enrollment)4
Body Composition (body mass index)
body mass index obtained using a multi-frequency bioelectrical impedance device (profiling purpose only; not included as a primary outcome).
