Caffeine can enhance athletic performance by increasing endurance, improving reaction times, and reducing perceived exertion during workouts. It stimulates the central nervous system, leading to increased alertness and reduced fatigue. Caffeine can also enhance the body’s ability to mobilize fat stores for energy, improving overall exercise performance, especially in endurance sports. However, individual responses can vary, and excessive consumption may lead to negative side effects such as anxiety or gastrointestinal distress. It’s important for athletes to understand their tolerance levels and consume caffeine strategically to maximize its benefits.
