Intraindividual differences in susceptibility to motion sickness were measured in 14 subjects for two conditions of rotation at 30 rpm in the 10 degree head-down position. In one condition, subjects were in the 10 degree head-down position for 6 h prior to the onset of rotation; in the other condition, the delay was only 15 min. In both conditions, there were changes in vital capacity, indicating a redistribution of movable body fluids. Subjects tended to be less susceptible to motion sickness when they were recumbent for 6 h prior to rotation. These results are countervidence for the hypothesis that shifts of body fluid are responsible in large part for the motion sickness elicited in orbital space flight.
在14名受试者中测量了个体对晕动病易感性的差异，这14名受试者在头部向下倾斜10度的情况下以30转/分钟的速度进行了两种旋转条件测试。在一种条件下，受试者在开始旋转前处于头部向下倾斜10度的位置6小时；在另一种条件下，延迟仅为15分钟。在这两种条件下，肺活量都有变化，表明可移动体液发生了重新分布。当受试者在旋转前仰卧6小时时，他们往往对晕动病的易感性较低。这些结果是对体液转移在很大程度上导致轨道太空飞行中引发晕动病这一假设的反证。
