[Cardiovascular system reaction to periodic head-to-tail G-force effects on a short-radius centrifuge]

As a result of 370 experiments in a 2 m-arm centrifuge, high human tolerance to acceleration of +0.8, 1.2 and 1.6 Gz (at the level of feet) was demonstrated. Cardiovascular reactions depended on the value, duration and frequency of acceleration exposures. Cardiovascular responses included, primarily, changes in regional circulation of the legs.
