Sports drinks are significant during prolonged exercise as they provide electrolytes and carbohydrates essential for sustained energy and hydration. During extended workouts, the body loses fluids and electrolytes through sweat, and consuming sports drinks helps to replenish these losses. Additionally, the sugars in sports drinks offer quick sources of energy, which can enhance endurance and performance. However, it is crucial to choose appropriate drinks that match the duration and intensity of the exercise while considering overall nutrition.
