This observational study aims to analyze hip rotator strength and range of motion, comparing measurements taken with the hip positioned at 90° and 0°. Clinical history data, as well as hip strength and range of motion measurements, will be collected during the 2022/23 and 2023/24 seasons.

This cross-sectional observational study aims to analyze the relationship between hip rotator strength and range of motion, comparing measurements taken with the hip positioned at 90° and at 0°. The study seeks to determine whether hip position influences the assessment of rotational strength and flexibility, providing useful information for both clinical evaluation and athletic performance monitoring. Data will be collected through direct measurements of hip strength and range of motion. Assessments will be performed during the 2022/23 and 2023/24 seasons. The findings are expected to contribute to a better understanding of how hip joint positioning affects rotator muscle function and mobility in healthy and active individuals.

Inclusion Criteria:

• male amateur soccer players
• aged between 18-50
