Caffeine consumption can significantly enhance athletic performance by increasing alertness and improving endurance. It stimulates the central nervous system, leading to heightened focus and reduced perception of effort. This can result in longer training sessions and improved performance in endurance activities. However, tolerance may develop over time, diminishing its effects, and excessive intake can lead to dehydration or jitters, adversely impacting performance. Therefore, moderate intake—typically around 3 to 6 mg/kg of body weight—is often recommended for optimal results without negative side effects.
