Caffeine enhances exercise performance by increasing endurance and reducing perceived exertion. When consumed prior to workouts, it can boost metabolic rate and improve focus, allowing for more intense physical activity. Studies suggest that caffeine can help reduce muscle soreness and fatigue, enabling individuals to train harder and longer. The interaction between caffeine and exercise can lead to enhanced performance, particularly in endurance sports, although individual responses may vary. Proper timing and dosage of caffeine intake are essential for maximizing its benefits.
