Electrolytes, including sodium, potassium, and magnesium, play a critical role in maintaining hydration and supporting nerve function during physical exercise. They help regulate muscle contractions and ensure proper fluid balance within the body. During intense workouts, electrolytes lost through sweat must be replenished to prevent cramping and fatigue. An adequate intake of these minerals before, during, and after exercise is essential for optimizing performance and recovery, thereby enhancing overall athletic ability.
