Volleyball Players' hidden shoulder issue may impact game performance
NCT ID NCT07372274
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 52 male teen volleyball players (ages 14-18) to see if a common shoulder tightness called GIRD affects their shoulder endurance and stability. Players with at least 10 degrees less inward rotation in their spiking shoulder were compared to those without. Researchers used simple physical tests to measure endurance and stability, aiming to understand if GIRD is linked to weaker performance even without pain.
