From the point of view of chemistry, lactic acid is a product of decomposition, or glycolysis of two substances - glycogen and glucose.
It is during the glycolysis that the release of energy, so necessary for athletes during training, occurs.
Where did the opinion about the excess of lactic acid in the body go?
There is a common opinion that lactic acidCauses athletes a lot of problems and is a real enemy, a serious obstacle to a successful sports career. It is believed that if the athlete's body contains a level of lactic acid higher than normal, he experiences severe pain and muscle cramps, and oxygen starvation may occur.
To learn more about the truthfulness orFalsity of this stereotype, we must first turn to biochemistry. Formally, lactic acid is a glucose molecule split in two, which, in the process of cleavage-glycolysis, releases special substances-pyruvates. These substances are used by human muscles as an energy fuel, and without them the muscles simply can not contract and relax, which means complete inaction.
Especially a lot of pyruvates because of increasedThe intensity of glycolysis is released during physical training, and the excess of this substance is eventually converted back to lactic acid. That is why intensive training often leads to an excess of lactic acid in the muscles of athletes. However, the view that lactic acid causes a characteristic pain that usually catches up athletes and bodybuilders a few days after training has not been confirmed and scientifically proven. Fifteen years have passed since scientists discovered the true cause of post-training muscle pains - these are banal micro-traumas of muscle fibers associated with an unusually heavy load.
Why does the body need lactic acid?
Lactic acid is the most important source of energy forOf the whole organism. If the sports training is very high intensity, the lactic acid produced in so-called fast fibers is transported to slow fibers, where it is then converted into energy fuel.
It is in the athlete's muscles that threeA quarter of the total volume of lactic acid produced. Still about a quarter of lactic acid from muscle fibers gets through the circulatory system into the liver and kidneys, where it is successfully processed. Thus, the widespread conviction about the so-called "surplus" lactic acid in the body does not have any scientific confirmation for today.
