title: [Regulation of the vertical posture after flights on the Saliut-4 orbital station].
abstract: Stabilographic examinations of the crewmembers of the orbital station Salyut-4 demonstrated that one of the most characteristic manifestations of posture-tonic deconditioning induced by a prolonged exposure to weightlessness was an emergence of high-frequency oscillations (with a cycle of 0.1--0.15 sec) of the common center of body gravity, the fraction of the oscillations decreasing during the first weeks of the postflight period. After flight all the crewmembers showed signs of postural hypotension: an increase in the cardiac rhythm and a decrease in the pulse arterial pressure.
