Alactic
Definition
Not producing lactic acid, preventing its accumulation, or pertaining to a metabolic process carried out structurally without lactate generation. In exercise physiology, the term qualifies anaerobic alactic energy metabolism, wherein the energy required for short-duration explosive muscle contractions is supplied exclusively by phosphocreatine breakdown, without the intervention of anaerobic glycolysis.
