The Effects of Sleep Deprivation on Physiological and Perceptual Responses During Exercise

Overview

Sleep deprivation has been found to impact exercise performance. The effects of both partial (several hours) and full (24+ hours) sleep deprivation on exercise performance has shown effects on rating of perceived exertion, rate of oxygen consumption, respiratory exchange ratio, and heart rate. A common practice with athletes is to perform regular physiological testing (submaximal and maximal) in order to assess their fitness and to determine training intensities. However, the effects of sleep deprivation on those same physiological test results has not been investigated Therefore, the purpose of this study is to investigate the effects of partial sleep deprivation on physiological test results.
