Abstract

We investigated the effect of change in intrathoracic pressure by total body negative pressure (TBNP) or positive pressure (TBPP) on thermoregulatory responses during -6 degree head-down bed rest (HDBR). Eight healthy male subjects participated to three of the following interventions in a randomised sequence: 1) HDBR, 2) HDBR with TBNP of -15 cmH2O, 3) HDBR with TBPP of +15 cmH2O. A rapid decrease of cutaneous blood flow occurred after the start of TBNP. In contrast, cutaneous blood flow increased slightly at TBPP. Sweat rate decreased immediately after the start of TBNP. Immediately after the TBPP was started, tympanic temperature greatly decreased. It is concluded that combination of HDBR and intrathoracic pressure changes thermoregulatory responses through the cardiopulmonary baroreceptor to reduce the wall stretch. more...
