Hydration significantly affects athletic performance and recovery. Adequate fluid intake helps regulate body temperature, maintain blood volume, and improve muscle function. Dehydration can lead to decreased strength, endurance, and concentration, negatively impacting overall performance. After exercise, proper hydration is crucial for recovery, as it aids in nutrient transportation, reduces muscle soreness, and facilitates the repair of tissues. Athletes should regularly monitor their hydration status and drink fluids before, during, and after activity to optimize performance.
