Sodium Bicarbonate

Controlling the pH of the blood in the body is essential for all normal body functions. Sodium bicarbonate is one of the major substances in the body that controls the pH of the blood. During exercise the body produces excess acid. This excess acid causes the pH to drop. This drop decreases the efficiency of the muscles. By taking sodium bicarbonate, athletes try to maintain their body's pH level. Athletes take it to improve performance.


Athletes use sodium bicarbonate as a performance aid for events of a particular duration. Sodium bicarbonate is not effective for events that are shorter than about 20 seconds or lasting longer than about 7 minutes.
