Exercise Thermoregulation After Prolonged Wakefulness,

Abstract

The effect of 33 hours wakefulness on the control of forearm cutaneous blood flow and forearm sweating during exercise was studied in three men and three women (follicular phase of the menstrual cycle). Subjects exercised for 30 min at 60% peak VO2 while seated behind a cycle ergometer. Esophageal temperature (Tes), mean skin temperature (Tsk), and arm sweating to Tes tended to be lower,but was not significant. Arm skin temperature was not different between control and sleep loss experiments. Reflex cutaneous vasodilation during exercise appears to be reduced by both central and local factors following 33 hours of wakefulness.
