What do sports drinks often include to help replenish lost fluids?

Sports drinks are designed to effectively replenish lost fluids and provide energy during and after intense physical activities. The inclusion of both carbohydrates and electrolytes makes them particularly effective for this purpose.

Carbohydrates in sports drinks serve as a quick source of energy, which is crucial during prolonged exercise when glycogen stores in the body may become depleted. This energy boost helps athletes maintain performance levels and delay fatigue.

Electrolytes, such as sodium and potassium, are essential for maintaining fluid balance in the body. They help replace the minerals lost through sweat and are crucial for proper muscle function and hydration. The combination of carbohydrates and electrolytes ensures that sports drinks not only hydrate but also promote recovery and replenish energy levels, making them a valuable resource for athletes during and after competition.

Water, while a fundamental component of hydration, does not provide the additional energy or electrolyte replenishment that carbohydrates and electrolytes offer. Fiber, on the other hand, is not typically found in sports drinks as it can be counterproductive to immediate hydration and digestion during intense physical activity. Therefore, the inclusion of both carbohydrates and electrolytes is what makes the correct answer accurate, as they work together to enhance hydration and energy restoration.
