... the United States and Russian programs have extensively used a number of countermeasures to maintain the crew's health and fitness, the premise that maintaining crew fitness results significantly in reducing the adverse effects of prolonged exposure to a microgravity environment. These effects vary from the onset of orthostatic intolerance following short-term space flight to the development of bone demineralization following long-term space flight. One thing is clear and that is the variable gravitational fields and the numerous translations found during space travel underscore the need to be prepared for all contingencies.
