The purpose of this paper is to qualify developments in the human body during long-term exposure to microgravity in the light of current physiological and pathophysiological postulates. The work is grounded on the analysis of the data about human body reactions to extended stay in microgravity and adopted from the literature. The syndrome of space motion sickness (SMS) evolving at the onset of space flight can be qualified as a temporary reaction to inadequate ambient conditions. In long-term microgravity after mitigation of SMS by dint of appropriate countermeasures, no subjective disturbing symptoms are virtually present. Performance remains on a sufficiently good level, and the body develops stable adaptive reactions and establishes an adequate homeostasis. Back to Earth, the human body undergoes a number of changes which can be qualified as a transient gravity-induced syndrome associated with readaptation of partly deconditioned body to the normal gravity forces.
本文的目的是根据当前的生理和病理生理假设，对长期暴露于微重力环境下人体的变化进行描述。这项工作基于对人体在微重力环境下长期停留反应数据的分析，这些数据取自文献。太空飞行开始时出现的太空运动病（SMS）综合征可被视为对不适应环境条件的一种暂时反应。在通过适当对策缓解SMS后长期处于微重力环境中，几乎不会出现主观不适症状。身体机能保持在足够良好的水平，身体会产生稳定的适应性反应并建立适当的内环境稳态。回到地球后，人体会经历一些变化，这些变化可被视为一种与部分机能失调的身体重新适应正常重力相关的短暂重力诱导综合征。
