Caffeine can significantly affect athletic performance and recovery. It acts as a stimulant, increasing alertness and reducing perceived effort during workouts. This can lead to enhanced endurance, strength output, and overall exercise capacity. Additionally, caffeine can improve recovery by promoting glycogen resynthesis and reducing muscle soreness. However, the effects can vary based on individual tolerance and timing of consumption, with optimal benefits typically seen with moderate doses. To harness caffeine's potential, athletes should experiment while considering their unique responses and needs in training and competition.
