title: [Hemodynamics of healthy persons under various regimens of negative pressure around the lower half of the body].
abstract: Thirty male athletes kept in recumbency served as test subjects in 90 LBNP experiments. In the experiments the negative pressure level varied from 40 to 80 mm Hg. During LBNP application the heart rate, arterial pressure, cardiac output, vascular tone and other parameters of circulation were measured. Cardiac output stabilized whereas other cardiovascular parameters changed significantly. Mechanisms of compensatory reaction during LBNP application and indications of its tolerance are discussed.
