Alveolar hyperventilation leads to a decreased partial pressure of arterial carbon dioxide (PaCO2). The decrease in bicarbonate is accompanied by the deviation of serum pH below 7.35.
It is called Respiratory Acidosis. It´s blood pH imbalances. Muscle fatigue is associated with a rapid increase in the production of metabolic acids. Tolerance to high intensity exercise may be limited by the body's ability to dampen the decrease in intracellular (muscle) and extracellular (blood) pH, that is, the intrinsic buffer system.
