To quantify the effect of 60 mm Hg lower-body positive pressure (LBPP) on orthostatic blood-volume shifts, the mass densities (+/- 0.1 g.1-1) of antecubital venous blood and plasma were measured in five men (27-42 years) during combined tilt table/an

To test the hypothesis that ancillary arm and hand exercise would change the values of antecubital blood constituents during leg exercise, seven healthy men (19-27 yrs) performed static (10% of a maximal voluntary contraction) or dynamic (60 finger f

To investigate the effects of lower body positive pressure (LBPP) on kidney function while controlling certain cardiovascular and endocrine responses, seven men [35 +/- 2 (SE) yr] underwent 30 min of sitting and then 4.5 h of 70 degrees head-up tilt.

To study the effects of nonosmotic and nonvolumetric factors that may influence secretion of vasopressin, serum Na+, K+, and osmolality (Osm), hemoglobin, hematocrit, plasma arginine vasopressin (AVP), aldosterone (PA), and renin activity (PRA) were

Blood pressure, pulse rate (PR), serum osmolality and electrolytes, as well as plasma vasopressin (PVP) and plasma renin activity (PRA), were measured in five men and two women [mean age 38.6 +/- 3.9 (SE) yr] before, during, and after inflation of an

Some physiological responses to head-up tilt and 3 h standing were evaluated in 13 dehydrated subjects. Seven of the subjects proved to be orthostatically intolerant (INT), exhibiting presyncopal symptoms. Before the symptoms manifest themselves the

Rectal (Tre) and mean skin (Tsk) temperature, skin heat conductance (Ksk), heart rate, and total body sweat rate were measured in 6 men (20-35 years) during 70 min of supine leg exercise (Ta = 23.5 degrees C, rh = 40%) at 50% of their peak O2 uptake

If plasma vasopressin (PVP), plasma renin (PRA), and plasma aldosterone (PA) responses to change in posture are mediated only by alterations in intrathoracic baroreceptor activity, hydration status should have minimal influence on these responses. To

To investigate fluid, electrolyte, and plasma vasopressin (PVP) and renin activity (PRA) responses, six men (20–35 yr) were immersed to the neck (NI) in water at 34.5 degrees C for six h after overnight food and fluid restriction. Diuresis was 1,06

To test the hypothesis that moderately intense physical training has no effect on orthostasis, orthostatic and fluid-electrolyte-endocrine responses to 60 degrees head-up tilt were compared before and after 6 h of water immersion (34.5 +/- 0.1 degree
