Question

Quizplus · Accepted Answer

Slow, steady aerobic activity, such as jogging or cycling at a moderate pace, primarily relies on fat as the main source of energy. This is because the body has enough oxygen available to break down stored fat into energy as well as use the oxygen from breathing to convert glucose into energy. As the intensity of the activity increases, the body begins to shift to using more carbohydrates as the main energy source.
