| So I used the first 900 meters of the 1500 as a warm-down to flush the lactic acid out of my system. |
| Undigested lactose fermented by bacteria creates lactic acid in the stool and other short chain fatty acids such as butyric acid. |
| The lungs also contribute to this process by eliminating carbon dioxide which is the waste byproduct of glucose and lactic acid metabolism. |
| Muscle glycogen breakdown leads to lactic acid production, which fatigues the muscle. |
| It does so by drawing on its store of glucose, which it converts to lactic acid. |
| Your muscles become cramped from lactic acid and from the number of hours you're standing upright. |
