The paper summarizes results of experiments on the influence of space flight and anti-orthostatic hypokinesia on the amino acids spectrum of human blood plasma. Our findings give evidence for: (i) A specific norm of the content of free amino acids in plasma during training and (ii) consistent changes of plasma aminograms during space flight related to its duration and to individual features of cosmonauts. The content of free amino acids in the plasma of bed-rested subjects varied phasically and tended to increase practically at every experimental stage. The paper discusses the findings and possible mechanisms of the detected changes.
本文总结了关于太空飞行和抗直立性运动减退对人体血浆氨基酸谱影响的实验结果。我们的研究结果表明：（i）训练期间血浆中游离氨基酸含量的特定标准；（ii）太空飞行期间血浆氨基酸图的持续变化与飞行持续时间和宇航员的个体特征有关。卧床休息受试者血浆中游离氨基酸的含量呈阶段性变化，并且在每个实验阶段实际上都有增加的趋势。本文讨论了所检测到变化的研究结果和可能机制。
