Abstract
Objective: This study examined the effects of combined stroboscopic glasses and reaction-light training on visual abilities and sport-specific performance in collegiate male volleyball players.
Methods: In this randomized controlled trial, 26 collegiate male volleyball players were assigned to an experimental group (EG, n = 13) or an active-control group (CG, n = 13). Both groups maintained their regular volleyball training. Over 8 weeks, the EG completed combined stroboscopic and reaction-light training, whereas the CG performed duration- and volume-matched volleyball-specific tasks under normal visual conditions. Training was conducted three times per week for 30 min per session. Reaction time, eye–hand coordination, decision-making ability, coordination quality, agility, and defensive reception success rate were assessed before and after the intervention. Intervention effects were evaluated using two-way repeated-measures ANOVA, with improvement-score analyses and baseline-adjusted ANCOVA conducted as sensitivity analyses. Bonferroni correction was applied to secondary and exploratory outcomes.
Results: Defensive reception success rate showed a significant Group × Time interaction, F(1, 24) = 13.053, p = 0.001, partial η² = 0.352, with a between-group difference in change of 3.50% points (95% CI, 1.50–5.50). After Bonferroni correction, significant interactions remained for reaction time (adjusted p < 0.001, partial η² = 0.858), eye–hand coordination (adjusted p = 0.002, partial η² = 0.423), decision-making ability (adjusted p = 0.030, partial η² = 0.279), and coordination quality (adjusted p < 0.001, partial η² = 0.827). Agility was not significant after correction (adjusted p = 0.110).
Conclusion: Compared with matched volleyball-specific active-control training under normal visual conditions, combined stroboscopic glasses and reaction-light training may provide additional benefits for improving selected visual abilities and defensive reception performance in collegiate male volleyball players. The agility finding should be interpreted cautiously.
