[Work capacity evaluation and orthostatic tolerance in experiments with long-term isolation].

Orthostatic tolerance (OT) and physical performance were tested against the ground simulation of several spaceflight factors. Before and after prolonged isolation and confinement three human subjects were tested by tilting, LBNP, and graded incremental aerobic exercise in the sitting position. Results suggested good OT in all the subjects.

[The cardiovascular system function of the cosmonauts of the 6th prime expedition on the Mir station].

Medical results of inflight cardiovascular measurements made in the 6th prime crew at rest and during provocative graded bicycle exercises and LBNP tests are presented. The methods of electrocardiography, tetrapolar rheography, kinetocardiography, arteriovenous pulsography and tacho-oscillography have been used to examine the cosmonauts. Together with regular cardiovascular changes typical of microgravity effect the individual peculiarities of developing the control mechanisms are noted.

[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.

[Results of medical research carried out in 1985 on prolonged space flights].

This paper presents medical results obtained during the fourth expedition of five cosmonauts onboard orbital complexes Salyut-7--Soyuz-T-13 and Salyut-7--Soyuz-T-14. The cardiovascular system was examined using 36 resting and provocative tests. They were performed by means of electrocardiography, tetrapolar rheography, arteriovenous pulsography and tachooscillography.
