It has long been known that muscle cells produce lactate, not lactic acid. However, it does not cause muscle soreness after training.
During exercise, numerous chemical reactions occur in muscle cells. As a result of these reactions, various substances and byproducts accumulate, which causes water to enter the cells. This helps increase the pressure within and between muscle cells. This pressure, combined with the movement of molecules through muscle cells, can stimulate nerve endings and cause discomfort during exercise.
However, the pain and discomfort you feel a few hours or days after doing the exercises are due to other reasons. If you exercise more intensely than usual, this can cause microscopic damage to the muscles and the areas where they attach to tendons. This damage causes the release of ions and other molecules from the muscles, causing local swelling and stimulation of nerve endings. This is sometimes called delayed-onset muscle disease, or DOMS. As a result, the body’s response to the injury intensifies over the next few days, leading to muscle pain and movement problems.
But the good news is that muscles quickly adapt to activities that may initially cause muscle pain. Therefore, if you do not recover for more than two weeks, during and after the next workout you will experience much less discomfort and pain than before.
