title: [Principles of organizing efficient work and rest regimens for crews on prolonged space flights].
abstract: The work-rest cycles of Salyut-6 crews were investigated. Several modifications were detected: 24-hour static regimens (65-70%) and altered regimens (35-30%) with longer or shorter work-rest cycles. It is concluded that in prolonged space flights two regimens are allowed: principal regimens (normal static regimens of work and rest) used throughout the flight, and operational regimens (differing from 24-hour ones) used no more than once every 7-10 days.
