Effect of Caffeine Consumption at Different Times of the Day on Static and Dynamic Balance Performance

This study investigated the impact of caffeine consumption at different times of the day on static and dynamic balance performance in athletes. Thirty healthy participants underwent repeated static and dynamic balance tests under three conditions—baseline, caffeine, and placebo—at 09:00, 13:00, and 17:00 using the PROKIN 252 balance system. The results revealed no significant interaction between caffeine and time on balance performance. However, dynamic balance was better at 17:00, and both static and dynamic balance were negatively affected by caffeine compared to placebo. The findings contribute to understanding the combined effects of ergogenic aids and circadian rhythms on neuromotor performance.
