Rightly associated with high levels of muscular effort, lactic acid appears when the energy demand cannot be satisfied by the other two metabolisms: aerobic and anaerobic alactacid.
The production, tolerance and disposal of "lactic acid are trainable capacities, typical of purely anaerobic efforts over 4" "(up to over 10" ", depending on the muscular condition and subjectivity) and mixed aerobic-anaerobic lactacids, obviously above the anaerobic threshold.
So, even if apparently "unwanted", for some athletes lactic acid is a very important molecule; its management is in fact associated with specific muscular and metabolic adaptations fundamental to improving performance.
On the other hand, as usual there is no shortage of conjectures and related false myths. Some attribute to the "lactic acid a potential" chronic acidifying "role, therefore harmful for the state of health and for the aesthetics of the organism (formation of cellulite). Nothing scientifically proven or approved.

If in human eukaryotic cells the anaerobic glycolysis with the production of lactic acid constitutes a sort of "trump card" to be played in case of high and urgent energy demand, for other forms of life this is not the case.
Just think of the well-known lactic bacteria, which break down carbohydrates forming lactic acid in the normal cellular process thanks to which they survive and multiply; even for them, however, it constitutes a limit. By acidifying the substrate in which they multiply too much, they create an unfavorable environment for further proliferation.
In the oral cavity, the significant increase in lactic acid facilitates the onset of dental caries.
