Your aerobic energy system capacity is primarily dependent on your training status. Perhaps this is best illustrated during the Olympics, when we see world champion athletes accomplishing magnificent endurance feats at the world’s most competitive level. This is a spot-on example of the colossal potential of the human body to adapt to high-quality training. I tell my students that your aerobic energy system is analogous to a large double-decker bus with a hefty gas tank. Modern buses can travel at relatively moderate speeds for great lengths of time. Similarly, via the aerobic energy system, we can tap into our carbohydrate and fat reserves for fuel, and with the help of oxygen your body can exercise for long periods at light, moderate, or hard intensities. During prolonged workouts such as cycling, cross-country skiing, and distance running, your muscles are dependent on the aerobic energy system’s ability to continuously produce ATP. In my exercise science classes we call the aerobic energy system “mitochondrial respiration.”
