![]() ![]() 1 Muscles are also strongly affected by reduced loading demands in weightlessness. ![]() During long-term missions, astronauts suffer from osteopenia due to an increased osteoclasts-mediated bone resorption and decreased formation. Adaptation to reduced gravity implies first body fluids redistribution and unloading of weight-bearing bones and postural muscles. Weightlessness, as experienced by astronauts during space flights, affects physiological functions of the human organism that has evolved, like other organisms living on Earth, through continuous adaptation to the permanent gravitational field.
