Ninety-six healthy nonpilots, aged 21 to 50 years, were exposed to 228 rotations on a 7.25 m arm human centrifuge. The study demonstrated age-related changes in +Gz tolerance of 3 to 5 G (for 30 sec). The subjects at the age 31 to 40 years showed the highest tolerance while the subjects at the age 21 to 25 and 46 to 50 years the lowest tolerance. Young subjects (21-25 years old) often developed an asthenic type of the systolic pressure reaction in the ear lobe and visual disorders whereas older subjects (46-50 years old) displayed cardiac arrhythmias, lower heart rate and delayed recovery of blood pressure after exposure. It was also found that 60-80% subjects aged over 40 well tolerated acceleration of up to 5 G and therefore can be viewed as potential candidates for cosmonauts.
96名年龄在21至50岁之间的健康非飞行员在7.25米臂长的人体离心机上接受了228次旋转测试。该研究表明，在3至5 G（持续30秒）的+Gz耐力方面存在与年龄相关的变化。31至40岁的受试者耐受性最高，而21至25岁和46至50岁的受试者耐受性最低。年轻受试者（21至25岁）耳部常出现无力型收缩压反应和视觉障碍，而年长受试者（46至50岁）则表现出心律失常、心率降低以及暴露后血压恢复延迟。研究还发现，40岁以上的受试者中有60%至80%能很好地耐受高达5 G的加速度，因此可被视为潜在的宇航员候选人。
