Electrolytes, such as sodium, potassium, and magnesium, play a vital role during exercise by maintaining fluid balance and supporting nerve and muscle function. During physical activity, athletes lose electrolytes through sweat, which can lead to dehydration and muscle cramping if not replenished. Consuming electrolyte-rich beverages or foods can help restore lost minerals and maintain optimal performance. Proper electrolyte balance also assists in regulating blood pressure and preventing fatigue, making it crucial for enhancing endurance and overall workout effectiveness.
