Caffeine and Performance

Caffeine offers significant performance enhancements, particularly for endurance activities, when consumed in the right dosage—about one to three milligrams per kilogram of body weight, taken 30 minutes before exercise. Interestingly, even those acclimated to caffeine can still experience benefits, especially in reaction time and power output, after a brief period of abstinence. However, care must be taken to avoid excessive intake that could disrupt sleep.
