Depressed Sweating during Exercise at Altitude,

Abstract

Acute exposure to moderate and high altitude resulted in a decrease in the thermosensitivity of arm, chest and thigh sweating during light and moderate exercise. This effect was not accompanied by any change in the esophageal temperature threshold for sweating onset at any of the three sites. Whole body wettedness was decreased an average of 23% at high altitude during light (40% VO2 peak) and moderate (60% VO2 peak) exercise. There was no change in mean weighted skin temperature at either moderate or high altitude. Keywords: Exercise(Physiology), Hypobaria, Temperature regulation, Sweating, Stress(Physiology).
