Abstract
The purpose of the present study was to examine the influence of a respiratory acidosis on the blood lactate (La) threshold and specific blood La concentrations measured during a progressive incremental exercise test. It is concluded that respiratory-induced acid-base manipulations due to the inspiration of 4% CO2 have a negligible influence on the blood La response during a progressive exercise test at low and moderate power outputs. Lower blood La values are observed at maximal exercise with an induced respiratory acidosis but this negative influence is less than what has been reported for an induced metabolic acidosis.
