title: [Changes in the body weight of cosmonauts during a 140-day space flight].
abstract: During 140-day space flight body mass changes of the Commander and Flight-Engineer were measured. No correlation between body mass losses and flight duration was found. Greatest body mass losses occurred on MD 44--59 in Commander (2.3--2.4 kg), and on MD 86 in Flight-Engineer (5.4 kg). Later the losses decreased. The results suggest that body mass changes varied on an individual basis and depended on many spaceflight factors.
