Detailed explanation-1: -Carbohydrates (glucose/glycogen) serve as the primary source of fuel as duration and intensity increase. If exercise continues for a significant period of time, fatty acids will serve as the fuel source when glycogen stores are nearly depleted.

Detailed explanation-2: -Carbohydrate is the body’s main fuel during physical activity.

Detailed explanation-3: -Carbohydrates are the most important fuel for an endurance athlete during long intensive exercise. Carbohydrates are stored in the liver and in the muscles as glycogen.
