Sleep Deprivation and Exercise Tolerance.
Abstract
The purpose of this study is to identify the effects of sleep deprivation on the physiological and psychological responses to exercise. Standard techniques in human exercise physiology are utilized. During this year, we found that fragmenting two nights of sleep prior to heavy exercise had no effect on physiological response to that exercise. Heart rate, metabolic rate, and body temperature were identical to control, in contrast to sleepiness and mood disturbance, both of which were significantly elevated. In past work, such psychological effects were correlated with decreased exercise tolerance. Also, we found that a 36 hour sleepless period prior to prolonged mild exercise has no influence on physiological responses to that exercise, though it as well significantly elevated mood disturbance. Because neither form of sleep loss changed stress hormonal levels in subsequent exercise, we conclude that sleep loss of this form is primarily a psychological and not a physiological stress.
