[The adaptation of the blood circulation to the long-term microgravity: ballistic-cardiographic investigation during 14 month space flight].
Specificity of the use of ballistocardiography (BCG) in space flight is considered. In particular, the contactless method makes it possible to continue recording during the night hours and study the ultradian rhythms reflective of the state of higher autonomous centers. As was stated, on months 7 to 8 of the mission by cosmonaut-physician Polyakov the BCG amplitude rose in concert with activation of the higher autonomous centers that were apparently involved in maintaining the established cardiovascular homeostasis. By months 11 to 13 on mission, the BCG amplitude decline resulted in an increase in the SCG/BCG index representing the amount of myocardium energy spent on blood transport.
