Seven male rhesus monkeys, aged 3.5-4 years, were examined during clinostatic hypokinesia for 20-40 days and after exposure for 16 days. Parameters of the cardiovascular function, external respiration and body temperature were measured. During and after hypokinesia the amplitude of diurnal variations of heart rate tended to decrease. The position of heart rate acrophases shifted most during the first 3 weeks of hypokinesia and during recovery. Changes in the amplitude of diurnal variations of arterial pressure were different. The position of acrophases on the time axis was unstable and tended to recover by hypokinesia days 30-40 and then shifted again on the 1st recovery day. The amplitude of diurnal variations of the respiration rate increased, the position of acrophases on the time axis shifted and their width changed. By the 14th day of readaptation the diurnal dynamics of this parameter tended to recover. During hypokinesia the amplitude of diurnal variations of body temperature increased or decreased and the position of acrophases on the time axis remained stable.
对7只年龄在3.5至4岁的雄性恒河猴进行了研究，在斜床静止性运动减少状态下持续观察20至40天，并在暴露16天后进行检测。测量了心血管功能、外部呼吸和体温等参数。在运动减少期间及之后，心率的昼夜变化幅度趋于下降。心率高峰相位的位置在运动减少的前三周及恢复期间变化最为明显。动脉压昼夜变化幅度的变化则有所不同。高峰相位在时间轴上的位置不稳定，在运动减少的第30至40天趋于恢复，然后在恢复的第一天再次发生变化。呼吸频率的昼夜变化幅度增加，高峰相位在时间轴上发生移动且宽度改变。到重新适应的第14天，该参数的昼夜动态趋于恢复。在运动减少期间，体温的昼夜变化幅度增加或减少，高峰相位在时间轴上的位置保持稳定。
