Effects of Volleyball-Specific Stroboscopic Training on Neuro-Psychophysiological Responses Across Different Experience Levels: A Randomized Controlled Trial
In Brief
A clinical study evaluating Stroboscopic Volleyball Training and Conventional Volleyball Training (Control) for Athletes and 3 related conditions. Completed, enrolled 42 participants across 1 site.
Detailed Summary
This study aims to investigate the effects of an 8-week volleyball-specific stroboscopic training program on neuro-psychophysiological outcomes in female volleyball players with different levels of competitive experience. Participants will be categorized as novice, intermediate, or elite athletes and randomly assigned to either a stroboscopic training group or a control group. Both groups will continue their regular volleyball training, while only the intervention group will perform additional volleyball-specific drills using stroboscopic glasses. Neuro-psychophysiological assessments, including heart rate variability, electrodermal activity, functional near-infrared spectroscopy, dual-task performance, and eye-tracking measures, will be conducted before and after the training period. The study aims to determine whether stroboscopic training induces differential adaptations across experience levels and contributes to improved neuro-psychophysiological regulation associated with sport performance.
Study Details
Timeline
Interventions
Participants will perform volleyball-specific training drills while wearing stroboscopic glasses that intermittently restrict visual input. The training will be conducted three times per week for 8 weeks, totaling 24 sessions. Each session will last approximately 35 minutes and will include volleyball-specific drills such as passing, setting, receiving, rotation-based movements, and reaction-based tasks. Visual disruption parameters of the stroboscopic glasses will be progressively adjusted throughout the intervention period.
Participants will perform the same volleyball-specific training drills as the intervention group for 8 weeks under normal visual conditions, without the use of stroboscopic glasses. Training frequency, duration, and drill content will be matched to the intervention group.
