Abstract
The use for breathing of oxygen–helium mixtures (OHMs) heated substantially above the range of temperatures thermoneutral for humans is considered. The following results were obtained in experiments with volunteer subjects: (1) breathing of heated OHMs during recovery after exercise resulted in a decrease in the maximum concentration of lactic acid in the blood; (2) during and after breathing of heated OHMs, there was an increase in the lung diffusion capacity.
