Question

Quizplus · Accepted Answer

Short-duration, high-intensity activities are fueled primarily by glucose, which comes from carbohydrates stored in the muscles and liver. During intense exercise, the body relies on glucose for energy because it can be broken down quickly to provide fast energy. Fat and protein take longer to break down and convert into energy, so they are not as efficient for high-intensity activities. Vitamins and glycine do not provide energy for exercise.
