Abstract
The effect of prolonged (up to 4 months) breathing of an artificial atmosphere (AA) containing 21.3-26.3 kPa O/sub 2/ and 0.1-0.4 kPa CO/sub 2/ on the parameters of the cardiorespiratory system was studied in 20 volunteers, divided into two equal groups: an experimental group, which exercised on a bicycle ergometer three times a week, and a nonexercising control group. With increasing time in the AA, the subjects of both groups exhibited symptoms typical of moderate hyperoxia: decreases in pulse rate and minute blood volume, O/sub 2/ intake and CO/sub 2/ elimination, respiratory coefficient, and energy consumption at rest. At the same time, the coefficient of O/sub 2/ utilization, the minimal arterial pressure, and the peripheral vessel resistance increased. Exercise decreased these deleterious effects.
