Pair each source of fuel with when it is used by the body during exercise: 1. Phosphocreatine 2. Carbohydrate (anaerobically utilized) 3. Carbohydrate (aerobically utilized) 4. Fats

1. Utilized from a resting state to immediate start of exercise (excited state) 2. Utilized at the beginning of exercise from about 30 seconds to 2 minutes prior to the body reaching steady state. 3. Utilized throughout the duration of endurance exercise once the body has reached steady state of oxygen deficit. 4. Utilized throughout the duration of endurance exercise once the body is in a complete aerobic state.

List the order in which the body utilizes substrates from rest to steady-state exercise (moderate-intensity endurance exercise) to a short burst of high intensity exercise.

1. fats 2. carbohydrates 3. phophocreatine
