caffeine and sports performance

Caffeine is a natural stimulant found in coffee, tea, and some supplements that can enhance sports performance by increasing alertness and reducing perceived effort. It helps muscles use fat for energy, conserving glycogen stores, which can delay fatigue. Caffeine may also improve focus, reaction time, and endurance during exercise. However, individual responses vary, and excessive intake can cause side effects like jitteriness or dehydration. When used appropriately, caffeine is a legal, widely accepted ergogenic aid that can support athletes in training and competition, but it should be consumed responsibly and in moderation.
