Men (N = 13) were sleep deprived and then exercised on a cycle ergometer. Brain activity and mood state were monitored.
Sleep deprivation markedly increased sleepiness and disturbed mood. Exercise reduced the effects of deprivation for a brief time. Brain activity was altered after sleep deprivation and exercise.
