Caffeine consumption can impact physical performance in various ways, primarily enhancing endurance and mental focus. Moderate caffeine intake stimulates the central nervous system, increasing alertness and reducing perceived exertion during workouts. This effect can lead to improved performance, particularly in endurance activities, allowing individuals to train harder and longer. However, excessive caffeine may lead to dehydration, anxiety, or gastric discomfort, hindering performance. Individual tolerance varies, making it essential for people to assess their reactions to caffeine carefully. Overall, when consumed appropriately, caffeine can be a beneficial ally for enhancing physical performance.
