Quick Reference

The portion of oxygen consumed after exercise that removes excess lactic acid from the blood. A small amount of the excess lactic acid is excreted in urine and sweat; a little contributes to the manufacture of protein; some is converted to glucose or glycogen in the liver and muscle, but most of the lactic acid produced during exercise is reconverted into pyruvic acid and used in aerobic metabolism to form carbon dioxide and water. Approximately 5–10 L of oxygen forms the lactacid post-exercise oxygen consumption; it is usually higher in highly trained athletes, especially sprinters.
