title: Summing-up cosmonaut participation in long-term space flights.
abstract: The health condition and work capacity of space travellers during many flights remained adequate.  Medical examinations performed during and after space flights consistently revealed the following symptom-complexes:  space motion sickness, changes in the muscles system, hemodynamics, fluid-electrolyte balance and its regulation, calcium metabolism and bone density, transient erythrocytopenia and immunity decline.  This paper presents a detailed discussion of the changes observed in space flight.
