Caffeine can enhance exercise performance by increasing alertness, reducing perceived exertion, and improving endurance. It acts as a stimulant, stimulating the central nervous system and promoting the release of adrenaline. This can lead to improved focus and physical performance during workouts or competitions. Additionally, caffeine may help increase the utilization of fat as an energy source, sparing glycogen stores for longer-duration activities. However, individual responses to caffeine vary, and it’s essential to monitor consumption to avoid potential side effects.
