%X Purpose: Purpose of this study was to investigate of upper/lower trapezius (U/L)muscle strength ratio which has an important role on overhead scapular mechanics of adolescent volleyball players at Turkish Volleyball Federation Sports Highschool. Methods: Sixty students (32 women, 28 men) who are eligible and voluntary were included in this study. Isometric muscle strength was measured with hand-held dynamometer. Muscle strength tests were done as muscle specific when scapula was at the middle of muscle movement. Results: Upper trapezius muscle strength was found higher on the dominant side compared to non-dominant side (p<0.05). Lower trapezius muscle strength was found higher on the non-dominant side compared to dominant side (p<0.05). U/L Trapezius muscle strength ratio was found 0.95 on dominant side and 0.88 on the non-dominant side. Scapular depression was found stronger on the non-dominant extremity (p<0.05) while the other extremity was stronger for scapular elevation (p<0.05). Conclusion: As a result of this study, reference normative values of upper/lower trapezius muscle strength ratios in the adolescent volleyball players was determined. In order to our results, scapular muscle preferences of adolescent players have certain varieties between extremities. Dominant side which has stronger upper trapezius muscle makes us to think that the requirements of overhead mechanics can lead to scapular control alterations. These results can help to find the asymptomatic adolescent volleyball players who have higher risk of shoulder injuries
