[Effect of long-term anti-orthostatic hypokinesia on the composition of volatile metabolites in the exhaled air]. / Vliianie dlitel'noi antiortostaticheskoi gipokinezii na sostav letuchikh metabolitov v vydykhaemom chelovekom vozdukhe.

This paper presents measurements of volatile metabolites in the air exhaled by test subjects exposed to year-long antiorthostatic hypokinesia (-5 degrees). The test subjects were subdivided into two groups (Group A and Group B), which used different countermeasures. It was found that during the first 30 days of exposure exhalation of volatile metabolites reached a new and higher level. During test days 1 through 240 the content of volatile metabolites increased significantly in both groups; however the increase in Group B was less expressed than in Group A. At the final stage of the experiment, i.e. from day 240 through 370, the difference between the two groups was levelled off.
