Quizplus · Accepted Answer

At high intensities of exercise, the body relies heavily on muscle glycogen for energy. This is because the body can quickly break down glycogen into glucose for ATP production, which is needed for high-intensity activities such as sprinting or lifting heavy weights. Intramuscular fat and blood glucose may also contribute to energy production, but muscle glycogen is the primary source at very high intensities. Muscle protein is not a preferred source of energy during exercise, as it is needed for repairing and building muscle tissue.
