title: +Gx-tolerance in the final stage of space flights of various durations.
abstract: Study of acceleration tolerance at the final stage of orbital flights after exposure to weightlessness is an important element of medical support of space flights.  The cosmonauts tolerance to accelerations has been analyzed during 38 space missions of 8- to 326-day duration.  Tolerance to acceleration during descent in all cases was estimated as satisfactory.  Acceleration tolerance during the final stage of orbital flights depended on flight duration, individual tolerance and use of countermeasures.
