This study will evaluate the effects of daily paraxanthine supplementation on electronic gaming performance, cognitive function, sleep quality, and autonomic responses in healthy adult gamers. Participants will be enrolled in a randomized, double-blind, placebo-controlled, parallel-group study and assigned to receive either paraxanthine or placebo daily for 6 weeks.
Outcome measures will be assessed at baseline, Week 3, and Week 6 and will include electronic gaming performance, cognitive function, visual analog scale ratings, sleep quality questionnaires, hemodynamic responses, and heart rate variability. The study is designed to determine whether paraxanthine supplementation improves performance and selected physiological and psychological outcomes during prolonged electronic gaming sessions.
