Acid tolerance

An athlete’s acid tolerance favors the ability to continue muscle contraction for a period of time despite muscle acidity. Thus, acid tolerance plays a not insignificant role in anaerobic endurance performance.

From a biochemical point of view, it is known that there are individual differences and that there is a certain trainability of acid tolerance. In addition to the biochemical aspect of this ability, the psychological aspect also plays an important role. This means the maintenance of muscle work despite a strong feeling of pain in the stressed muscles. During endorphin release, the body’s own pain-blocking substances are released, by which this psychological pain suppression is further supported (Neumann, 1998 and Zintl 1997).
