1. Why is running a mile not a anaerobic exercise? 2. True or false, is running as fast as you can a anaerobic exercise?

1.  Because running longer distances allows the body for proper oxygen consumption (meaning, when you are “running aerobically”, your muscles have enough oxygen to produce all the energy they need to perform).

2. True. In this instance, the muscles do not have enough oxygen to create the energy you are demanding (usually from an increase in pace that is faster than your body is able to sustain, for example sprinting at the finish).

When running anaerobically, the muscles begin to break down sugar, but instead of producing just CO2 and water, they also produce excessive amounts of lactate.
