WATER INGESTION INCREASES SYMPATHETIC VASOCONSTRICTOR DISCHARGE IN NORMAL HUMAN SUBJECTS.

A marked pressor response to water drinking has been observed in patients with autonomic failure and in the elderly, and has been attributed to sympathetic vasoconstrictor activation, despite the absence of such a pressor response in healthy subjects with intact sympathetic mechanisms. We investigated whether water drinking in normal subjects affected peripheral sympathetic neural discharge [...]

VALIDATION AND ADJUSTMENT OF THE MATHEMATICAL PREDICTION MODEL FOR HUMAN SWEAT RATE RESPONSES TO OUTDOOR ENVIRONMENTAL CONDITIONS.

Under outdoor conditions this model was over estimating sweat loss response in shaded (low solar radiation) environments, and underestimating the response when solar radiation was high (open field areas). The present study was conducted in order to adjust the model to be applicable under outdoor environmental conditions. Four groups of fit acclimated subjects participated in [...]

WATER INTAKE AND URINARY VOLUME DURING 20 DAYS BED-REST IN YOUNG WOMEN.

During the bed-rest in the young subjects, the water intake should be depressed, because the diuretic is probably accelerated, and then the total body water and body weight is decreased by the water loss. In our previous study in 1991, we have reported that urinary volume was gradually increased, while water intake was decreased. Therefore, [...]
