The effects of sodium bicarbonate supplementation on physical performance.
A decrease in intramuscular pH, caused by excessive H+ production, has been known to be one of the causes of muscular fatigue during maximal exercise. The hydrogen ions are a result of anaerobic metabolism that is used to provide the muscle cell with the ATP needed during strenuous bouts of exercise. There have been a number of studies done in the area of increasing the ability of the blood to buffer these hydrogen ions as they are released into blood with lactate. Sodium Bicarbonate, or baking powder, is a strong base that is being looked at as a potential supplement for increasing the blood pH and therefore, the ability of the body to expel the metabolic waste as CO2. The majority of the carbon dioxide produced is transported in the blood to the lungs in the form of carbonic acid.
