Electrolytes play a crucial role during endurance activities as they facilitate hydration, nerve function, and muscle contraction. During prolonged exercise, the body loses electrolytes through sweat, particularly sodium and potassium. Maintaining proper electrolyte levels prevents cramping, dehydration, and fatigue, allowing for sustained performance. Consuming electrolyte-rich beverages or snacks during long workouts helps to replenish these essential minerals, ensuring optimal body function and enhancing overall exercise efficacy. Therefore, staying hydrated with electrolyte management is vital for serious athletes.
