用头低倾斜位（－１０°）模拟失重时的心血管效应，观察和比较了１６名健康青年被试者分别在平卧和头低位两种体位下，平行秋千摆动诱发运动病易感性的差别及头低位１ｈ期间的反应症状；在实验前、中、后测试了心输出量、心率和血压。结果表明，头低位下的秋千运动病易感性比平卧位明显增高（Ｐ＜０．０１）。值得注意的是，在头低位１ｈ期间，有５６％的被试者出现头部不适反应症状，秋千运动病易感性的增高比没有头部不适症状的被试者更为显著。可以认为，在头低位倾斜时的运动病试验可以暴露那些对体液头向转移适应性差，从而影响运动病易感性的人．
Using the low tilt head (-10 °) to simulate the cardiovascular effects during weightlessness, 16 healthy young subjects were observed and compared in the supine and low head two positions, parallel to swing swing-induced motion sickness Differences and head low 1h during the reaction symptoms; in the experiment before, during and after testing cardiac output, heart rate and blood pressure. The results showed that the swing motion sickness under the head low was significantly higher than that of the supine position (P <0.01). It is noteworthy that 56% of the subjects experienced symptoms of headache discomfort during 1 h of head down, and increased susceptibility to swing motion was more pronounced than those without head discomfort. It is believed that motion sickness tests at low head tilt may expose those who have poor adaptability to the head of the fluid and thus affect the susceptibility to motion sickness.
