Lactic Acid is produced mainly in the anaerobic stage of exercise3. During this stage, lactic acid is produced as a byproduct of the ATP-CP metabolism system or the Glycolysis system. Both metabolism processes produce ATP quickly but do not in large quantities. As opposed to the Krebs cycle however, or the electron transport chain system in which fat is used as the main fuel source and yields a lot more ATP per cycle. Lactic acid buildup can cause fatigue in the muscle but can be helpful in understanding the limitations within a given exercise. The Lactate Threshold, also recognized as the point in which your body begins producing lactic acid due to anaerobic fatigue, can be a challenging wall to get through. Interval training and training within Zone 3 (70-80%) of your maximal heart rate can help increase the threshold.Dbaladi10 (talk) 21:34, 24 April 2013 (UTC)
