How does caffeine affect athletic performance?

Caffeine is well-recognized for its ergogenic effects, particularly in enhancing endurance performance. This stimulant influences the central nervous system and can increase alertness, reduce perceived exertion, and improve focus. By mobilizing fatty acids for energy, caffeine enables athletes to conserve glycogen stores, which is crucial during prolonged physical activity. This mechanism allows for improved endurance and potentially better athletic performance over extended periods.

Research shows that moderate doses of caffeine can lead to significant improvements in endurance activities, such as running or cycling, making it a popular choice among athletes looking to enhance their performance. Thus, the assertion that it can enhance endurance performance is well supported in the literature surrounding sports nutrition and exercise physiology.
