Caused by strenuous exercise causes acidosis

Strenuous exercise acidosis caused when there is another reason. Adenosine triphosphate is split in the release of energy when it releases a proton, these protons is causing Lactic acid. In the intense aerobic metabolism during exercise (Aerobic Metabolism) can not guarantee the production of adenosine triphosphate, so anaerobic metabolism (Anaerobic Metabolism) begins. This process can produce a large number of adenosine triphosphate, adenosine triphosphate which the release of a large number of protons in the decomposition, buffered lactic acid of the tissue, causing acidosis. This is perhaps the intense muscle pain during exercise one of many reasons.
It was considered by the strong ion concentration gradient can cause lactic acidosis, but the study of this process is imperfect, it is unclear whether there.
