Abstract
Both lower body positive pressure (LBPP) and head-down tilt (HDT) can induce fluid shifts from the lower body to the thorax and result in a loading of cardiopulmonary baroreceptors. The aim of this study was to compare the effects of LBPP and HDT on cardiovascular responses in humans. To accomplish this, a graded LBPP test of 10, 20 and 30 mmHg, as well as a 6 degrees HDT was applied. It has been suggested that <20 mmHg LBPP and <30 degrees HDT load the cardiopulmonary baroreceptors by translocation of blood volume from the lower body to the thorax, while >20 mmHg LBPP activates the intramuscular pressure-sensitive receptors.
