Proper hydration is critical for athletic performance, as it affects physiological functions like temperature regulation and nutrient transport. Dehydration can lead to fatigue, reduced endurance, and impaired cognitive function, negatively impacting overall performance. Athletes should aim to maintain optimal hydration levels before, during, and after exercise to ensure peak physical performance. Electrolyte balance is also vital, especially in prolonged or intense activities, to prevent cramping and optimize muscle function. In summary, adequate hydration supports all aspects of athletic performance and recovery.
