[Anthropometric studies of crew members of Salyut-6 and Salyut-7].

The paper presents body mass and leg volume measurements of 21 prime crewmembers of Salyut-6 and Salyut-7 flights. It was found that body mass variations were different in sign. In most crewmembers body mass decreased by 1.

Medical investigations results obtained in 125-day flight on "Salyut-7" and "Mir" orbital stations.

In 1986 in USSR medical investigations were continued in 125-day flight on "Salyut-7" and "Soyuz-T-15" orbital stations and on "Mir" basic block. Medical program consisted of medical control during active parts of flight and works in open space, profound medical examinations in rest and in function tests, metabolism and its regulation analysis, hygienic estimation of environment, estimation of prophylactic methods to prevent unfavourable influence of weightlessness on human organism. Cosmonauts felt well in all parts of flight on the dates of radio exchange, TV-seances, self- and each other control.

[Changes in the body weight of cosmonauts during a 140-day space flight].

During 140-day space flight body mass changes of the Commander and Flight-Engineer were measured. No correlation between body mass losses and flight duration was found. Greatest body mass losses occurred on MD 44--59 in Commander (2.

[Effect of antiorthostatic hypokinesia and space flight factors on changes in crural volume].

The purpose of the present investigation was to assess, using a specially built sensor, variations and level of fluid redistribution as well as atrophic changes in leg muscles of test subjects exposed to prolonged head-down tilt and cosmonauts in a real space flight. Hypokinetic test subjects were examined before, during and after head-down tilt, whereas cosmonauts were examined before and during flight. The results obtained show that a change in the hydrostatic component of blood pressure is followed by displacement of a substantial fluid volume (about 7%).
