Abstract
Purpose: This study investigated the effects of sport-specific SVT on dynamic balance and joint position sense in adolescent male volleyball players. Methods: Thirty adolescent male volleyball players (12–18 years) were randomly assigned to a stroboscopic vision training group (SVT, n = 15) or a control group (CON, n = 15). Both groups completed identical volleyball training twice weekly for 6 weeks, with the SVT group wearing stroboscopic eyewear. Dynamic balance was assessed using the Lower Quarter Y Balance Test, and proprioception was evaluated using active ankle (45° plantar flexion) and knee (60° flexion) joint position sense tests. Within-group and between-group comparisons were performed using the Wilcoxon signed-rank and Mann–Whitney U tests, respectively, and effect sizes were calculated as r. Results: The SVT group, significant improvements were found in dominant anterior (p = 0.006, r = 0.71), dominant posterolateral (p = 0.002, r = 0.79), nondominant posterolateral reach (p = 0.015, r = 0.63), and nondominant composite score (p = 0.046, r = 0.51), as well as nondominant ankle joint position sense (p = 0.027, r = 0.57). No significant between-group differences were found for dynamic balance or proprioception (all p > 0.05; r = 0.00–0.26). Conclusions: Both groups improved selected dynamic balance measures after 6 weeks of training. Although the SVT group demonstrated moderate-to-large within-group effects, SVT provided no additional benefit over conventional volleyball training.
