Evaluating the influence of sleep deprivation upon circadian rhythms of exercise metabolism

W J Montelpare et al. Can J Sport Sci. 1992 Jun.

Abstract

Cardiorespiratory and gas exchange responses to a moderate, standardized treadmill walking task showed a weak circadian rhythm, with larger superimposed peaks attributable to feeding. However, both rhythms became progressively attenuated during a period of sleep deprivation. A method of exploring this phenomenon is illustrated by an analysis of data on walking heart rate, respiratory minute volume, oxygen intake, and rating of perceived exertion, collected on 11 young men at 3-hr intervals during 60 hours of sleep deprivation.
