Ambient temperature affects glabrous skin vasculature and sweating responses to mental task in humans.
We compared responses in heart rate (HR), mean blood pressure (MAP), sweating rate (SR), sweating expulsion (SwE), and skin vascular conductance (VC) to mental task among different ambient temperature (Ta) conditions, i.e., 12, 16, 20, and 24 degrees C. Seven subjects (27+/-5 yrs, 64+/-14 kg) underwent a 2-min color word conflict test (CWT) after 2 mins of baseline data acquisition following a ...
متن کاملEffects of muscle metaboreceptor stimulation on cutaneous blood flow from glabrous and nonglabrous skin in mildly heated humans.
Given differences in sympathetic innervation to glabrous and nonglabrous skin, we tested the hypothesis that muscle metaboreceptor regulation of cutaneous vascular conductance (CVC) differs between these skin regions. Subjects (n = 21) performed isometric handgrip exercise (IHG; 50% maximal voluntary contraction for 60 s), followed by 2 min of postexercise ischemia. Throughout IHG and postexerc...
متن کاملPhysically Trained and Untrained Humans
The purpose of this study was to determine if the state of physical training influences sympathetic neural activation during acute stress in humans. We recorded muscle sympathetic nerve activity (microneurography of the peroneal nerve), arterial blood pressure, and heart rate in 12 highly trained, endurance athletes (25 ±1 years, mean±SEM) and 12 untrained subjects (27±1 years) before (supine r...
متن کاملInfluence of isometric exercise on blood flow and sweating in glabrous and nonglabrous human skin.
The distribution of the reflex effects of isometric exercise on cutaneous vasomotor and sudomotor function is not clear. We examined the effects of isometric exercise by different muscle masses on skin blood flow (SkBF) and sweat rate (SR) in nonglabrous skin and in glabrous skin. The latter contains arteriovenous anastomoses (AVAs), which cause large fluctuations in SkBF. SkBF was measured by ...
متن کاملVibrotactile perception at glabrous and nonglabrous skin of fingers: repeatability of measurements and changes induced by acute vibration exposure.
OBJECTIVES We sought to determine the within-session and between-session repeatability of vibrotactile perception threshold (VPT) measurements and the response patterns in VPT induced by acute exposure to short-term vibration from grasping a vibrating handle, at both glabrous and nonglabrous skin of fingers. METHODS Baseline VPT was recorded twice at glabrous and nonglabrous side of fingers i...
