Summary
This study looks at whether core endurance and scapular control are linked to shoulder pain in adolescent female volleyball players aged 14 to 18. Participants will undergo tests for pain intensity, scapular movement, and trunk muscle endurance. The goal is to better understand factors that may contribute to shoulder pain in this sport and help design future prevention strategies.
