Effects of combined -6° head-down bed rest and total body negative or positive pressure on thermoregulatory responses

Abstract

We had already observed the ability of sweating reduce after -6 ° head-down bed rest of two weeks, and concluded that dehydration by the increase of urine excretion was a cause. However, it is known that reduces the intra-thoracic wall at the space flight, and a urine excretion is not observed. We investigated the effect of combined -6° head-down bed rest and total body negative or positive pressure on thermoregulatory responses. [J Physiol Sci. 2007;57 Suppl:S179]
