Özet

This study investigates the intra-day and inter-day reliability of the athletic shoulder test (IYT test) in volleyball players. Twenty experienced players aged 14.48±1.327 years participated, with no chronic health issues or injuries. Using a prospective cohort design, participants performed three trials in I, Y, and T positions with both dominant and non-dominant arms over two separate days. Reliability was assessed using standard error of measurement (SEM), minimum detectable change (MDC), and coefficient of variation (CV). Intra-day ICC values ranged from 0.908 to 0.969, and inter-day ICC values ranged from 0.819 to 0.948. SEM values varied from 1.996 to 6.781 N, while MDC values ranged from 5.533 to 18.708 N. CV values were within acceptable limits. These results indicate that the athletic shoulder test using the Wii Force Platform provides good to excellent reliability for both intra-day and inter-day measurements in volleyball players.
