lactic acid

Glucogen is stored in your muscles, glucose is basically sugar, gylcolysis breaks up into atp and pc glucogen glycolysis is the process that helps the atppc system to run so it allows the system to keep going.  lactic acid feels like its burning and can only last up to 40-60secs; the lactic acid slows you down what you need is oxygen to get to your glucogen. Also lactic acid makes you feel pain so for example, when you do push ups if you feel the pain after about 10seconds is the lactic acid, so like i said what you need is oxygen to help break up the lactic acid. Also when the atppc system runs out your body switches to the lactic acid system.
