On the basis of experiments on 122 healthy male test subjects the norms of reactions of cerebral circulation to antiorthostatic exposures, basic principles and evaluations of its antiorthostatic tolerance (AOT) were established. The level of AOT was found to increase in acrobats in the course of their training, in test subjects after 30-day head-down tilting, and in space crewmen postflight. This increase can be regarded as an adaptive reaction of cerebral circulation to the excess blood rush to the head both on the Earth and in weightlessness. The similarity of regulatory hemodynamic changes in the above groups shows the possibility and indicates approaches to the ground-based training of cerebral circulation aimed at facilitating and accelerating its adaptation to weightlessness.
基于对122名健康男性受试者的实验，确立了脑循环对抗立位暴露的反应规范、其抗立位耐力（AOT）的基本原则及评估方法。研究发现，杂技演员在训练过程中、受试者在进行30天头低位倾斜后以及航天乘员在飞行后，其AOT水平均有所提高。这种提高可被视为脑循环对地球和失重状态下头部过度充血的适应性反应。上述各组调节性血液动力学变化的相似性表明了进行地面脑循环训练以促进和加速其对失重适应的可能性，并指明了方法。
