The production of lactic acid during vigorous activity is is the result of anaerobic reactions that take place by a resting muscle until maximum blood flow/oxygen in that muscle is achieved, and that this reaction--and the formatonn of lactic acid-- is actually fundamental to the initial performance of the muscle and the breakdown of carbs. (The chemicals involved in this anaerobic reaction are glycogen, phosphocreatine, hexesemenophosphate, and adenosinetriphosphate).
The anaerobic reaction whose byproduct is lactic acid seems to play a key role in initial process of muscular work--and energy derived from the oxidation process, although there is still some debate by scientists as to what extent those anaerobic (lactic-acid-producing) processes affect the performance/metabolism of an aerobic (oxygen-using) muscle. I hope this is helpful to you.
