a: lactic acid ~
b: a substitute for oxygen
What:
"When you are exercising anaerobically, your muscles don't have enough oxygen to fuel them. That is why you have lactic acid, lactic acid is like a substitute for oxygen. It is just another way to produce energy for your muscles. But this lactic acid is only used when your exercising anaerobically because it causes fatigue, and makes you tired faster."
