European isolation and confinement study. Lower body negative pressure tests.

From the LBNP experiment carried out during the ISEMSI project, we can conclude that there was no indication of the cardiac deconditioning syndrome in any of the six subjects. The absence of such effects can probably be ascribed to the following two conditions: (1) the subjects were not in inactive conditions; and (2) there was only a slight overpressure in the hyperbaric chamber.
