How does anaerobic activity “not use oxygen” if you’re breathing very heavily when you do it?
In: 0
During intense activity the muscles can’t get enough oxygen to the body to burn energy efficiently. It instead continues to burn energy in a way that keeps you going but only for shorter periods. This inefficient method creates a product called Lactic Acid. Lactic Acid is the burning sensation you get in your legs when running. To clear that lactic acid from the body the you still need oxygen to turn the lactic acid into something the body can move away from the muscles.
Therefore despite your muscles being able to function with not enough oxygen, eventually that oxygen debt you build up needs to be repaid through heavy breathing after the exercise.
