title: [Human body composition during extended stay in microgravity].
abstract: According to the Sprut-2 protocol, bio-impedancemetry of ISS cosmonauts was performed once a month and also before and after mission. Multiple non-invasive body measurements were carried out in 15 cosmonauts in real time. Relocation of extracellular liquid along the body axis led to its reduction in legs and, on the contrary, an increase in the abdomen. Volumes of total body liquid as well as intra- and extracellular liquids decreased in comparison with pre-flight levels. Lean body mass also became less in microgravity, whereas fat mass showed an increase.
