Basic results of medical studies during prolonged manned flights on-board the Salyut-7/Soyuz-T orbital complex

From 1982 through 1986 six extended flights (from 65 to 237 days) were carried out in the Salyut-7/Soyuz-T orbital complex by the principal crews, and five short-term flights (8 to 12 days) by visiting crews. During these flights, a broad series of medical studies was performed, their greatest extent during the longest flight (237 days), with the participation of a cosmonaut-doctor. The medical studies were aimed at obtaining additional information and new data on the reactions of the body's basic systems during a prolonged state of weightlessness.
