ABSTRACT
Cardiorespiratory responses of Salyut-4 crewmembers to exercises of 600 kgm/min performed for 7 min on a bicycle ergometer in the supine position were studied. It was found that the 30- and 63-day flights induced a certain decrease in the body response which included a less economic functioning of the cardiorespiratory system during exercise. The degree of postflight changes of the 30- and 63-day crewmembers was similar. At the same time the cardiorespiratory system of the 63-day crewmembers returned to the preflight level more rapidly than that of the 30-day cosmonauts.
