Abstract : This report evaluates and comments on the physiological effects of space flight on the circulatory system of both cosmonauts and animals. It compares these findings with those obtained with the use of laboratory simulators. The result of the effects of acceleration and weightlessness upon the body during space flight, both for animal and manned flights, is discussed. It is concluded that current data do not indicate what mechanisms are involved in adaptation of space flight. The author proposes three phases of adaptation and compensation reactions under weightless conditions: (1) the transition phase; (2) incomplete adaptation; and (3) relative stable adaptation. He also concludes that space missions of longer duration will be required to determine if complete adaptation can take place. (Author)
