Brief Summary

This randomized controlled study aims to investigate the acute effects of a single session of web-based visual training on balance, reaction time, and cognitive function in professional e-sports players. Participants will be randomly assigned to either a web-based visual training group or a control group. The intervention group will receive a single approximately 25-minute session including eye relaxation, eye movement exercises, convergence-divergence, accommodation, figure-ground perception, and visual attention exercises. The control group will receive no intervention. Balance, reaction time, and cognitive function will be assessed at baseline and immediately after the intervention.

Conditions

Cognitive Function; E-sports Performance; Reaction Time; Balance

Outcome Measures

Primary Outcomes (1)

• Reaction Time

  Reaction time will be measured using an LED-based system. The average reaction time (ms) and the number of correct responses will be recorded.

  Baseline and immediately post-intervention

Secondary Outcomes (2)

• Balance

  Baseline and immediately post-intervention

• Cognitive Function

  Baseline and immediately post-intervention

Interventions

Web-Based Visual Training BEHAVIORAL

Participants received a single session of web-based visual training lasting approximately 25 minutes. The session included eye relaxation, eye movement exercises, convergence-divergence, accommodation, figure-ground perception, and visual attention exercises.
