Which group commonly uses carbo-loading?

• A. Marathon runners
• B. Sprinters
• C. Weightlifters
• D. DiverS

Answer: (A)

Carbo-loading is about increasing glycogen stores in muscles and liver to fuel long-duration exercise. Marathon running is a prolonged activity that relies heavily on stored carbohydrates for energy over many hours. By boosting carbohydrate intake in the days before the race, runners can maximize these glycogen reserves, helping them maintain pace and delay fatigue. Other activities like sprinting, weightlifting, or diving rely more on short, high-intensity efforts or different energy systems, so loading up on carbohydrates before them doesn’t provide the same clear advantage and isn’t as commonly used.
