Microgravity during space flight induces physiological changes that affect astronauts' health
and performance. Space flight simulations such as prolonged bed rest can mimic some of these
changes and provide study conditions that are more accessible than during space flight. The
European Space Agency, ESA together with the French national space agency, CNES and the
Japanese national space agency, NASDA are performing extensive studies using long duration
bed rest.
Previous studies including several long and short term bed rest campaigns have yielded
significant medical data on the physiological changes induced by space flight. These data can
be used to study the effect of countermeasures, methods helping to prevent these
physiological changes.
The long duration bed rest, lasting 3 months undertakes a variety of investigations involving
28 subjects. This study focuses on countermeasures, studying the effect of a bone tissue
stabilisation medication and resistive exercises to determine their suitability for use
during long duration stays on ISS.
The physiological changes recorded during space flight and bed rest mimic those observed in
some diseases and in the aging process. Significant clinical applications are expected as a
direct result of this experiment and future equivalent studies.
