The effects of acetazolamide-induced carbonic anhydrase inhibition (CAI) on muscle intracellular thresholds for intracellular pH and inorganic phosphate-to-phosphate creatine ratio and the plasma lactate (La-) threshold were examined. The data suggest that the lower plasma lactate concentration seen...

Zusammenfassung:The effects of acetazolamide-induced carbonic anhydrase inhibition (CAI) on muscle intracellular thresholds for intracellular pH and inorganic phosphate-to-phosphate creatine ratio and the plasma lactate (La-) threshold were examined. The data suggest that the lower plasma lactate concentration seen with CAI was not due to a delayed onset of rate of muscle La- accumulation but may be related to impaired La- removal from muscle.
