    Abstract:
    Eleven healthy male volunteers, aged 45-55 years, with neurocirculatory dystonia of the hypertensive type were exposed to 7-day dry immersion. The following parameters were measured: central and peripheral hemodynamics (by the method of rheography), linear blood flow velocity, and orthostatic tolerance before and after immersion. During an acute period of adaptation to immersion the test subjects developed: centralization of blood filling of the head and lungs, decrease of stroke volume and cardiac output, increase of linear blood flow velocity in forearm arteries and its decrease in leg arteries, drastic decline of orthostatic tolerance.
