Abstract : The purpose of the study was to investigate the character and acuteness of statokinetic reactions of man under conditions of short duration weightlessness and their dependence on past flight experience, to elaborate criteria for evaluating statokinetic resistance to short duration weightlessness, and to study the adaptive capacities of the organism. The test subjects underwent multiple physiological studies of their sensory, vegetative, motor, and vestibulo-somatic reactions. During the familiarization flights for weightlessness, most of the test subjects showed statokinetic disturbances in the form of psychosensory, vegetative, and motor disorders. The degree of acuteness of the statokinetic disturbances was found to be in inverse relation to the previous flight experience of the test subjects, with disturbances being observed in 16.7% of the pilots and in 81.9% of the non-pilots during the first familiarization flights.
