Abstract : The purpose of the study is to identify the effects of sleep deprivation on the ability of humans to tolerate standard forms of endurance exercise. Standard techniques in human exercise physiology are utilized. To date, the results indicate that acute sleep loss of 30 to 36 hours (a) does not alter the maximal oxygen uptake, while it does reduce maximal heart rate; (b) leaves metabolic rate during exercise at a constant external work load unchanged, while heart rate is reduced and ratings of perceived exertion are elevated; (c) reduces tolerance of prolonged heavy exercise at three-fourths of the maximal oxygen uptake by about 10%, with wide variation noted among individuals, and (d) fails to significantly change work loads selected for equal effort during short-term heavy exercise.
