Experiments were performed to determine tolerance to head-to-feet (+Gz) acceleration in 62 test subjects aged 23 to 33 years. They were rotated in a human centrifuge before and after they consumed water and water-salt supplements under the conditions of normal activity or dry immersion simulating microgravity effects. During the centrifugation experiments the following parameters were recorded: stroke volume and cardiac output, arterial pressure by means of Korotkov sounds, electrolytes, total protein and hematocrit. Water and water-salt supplements were found to produce a beneficial effect on acceleration tolerance: tolerance threshold increased, stability of cardio-respiratory functions grew, cardiac arrhythmias developed less frequently. The efficacy of the methods increasing the hydration level was related to the amount of water consumed and retained in the body. It is recommended to use a differential approach to the development of procedures for increasing body hydration to be employed in aerospace medicine.
进行了实验，以确定62名年龄在23至33岁的测试对象对从头到脚（+Gz）加速度的耐受性。在正常活动或模拟微重力效应的干浸条件下，他们在饮用了水和水盐补充剂前后，在人体离心机中进行了旋转。在离心实验过程中，记录了以下参数：每搏输出量和心输出量、通过柯氏音测量的动脉血压、电解质、总蛋白和血细胞比容。发现水和水盐补充剂对加速度耐受性产生有益影响：耐受阈值增加，心肺功能稳定性增强，心律失常发生频率降低。提高水合水平方法的效果与体内消耗和保留的水量有关。建议在航天医学中采用差异化方法来制定增加身体水合的程序。
