Effect of a hypoxic-hypercapnic gas mixture (5% CO2 + 14% O2) on exercising men was studied. At a low work load, inhalation of this gas mixture inhibited gas exchange, and after a 10-mo. training, stimulated it. Increase in physical endurance was followed by an increase in human resistance to O2 deficiency and CO2 excess in the breathing mixture.
