Effects of Exercise, Bedrest and Napping on Performance Decrement during 40 Hours

Abstract

Young male Naval volunteers were denied normal nocturnal sleep and maintained on a 60-min treatment-160-min testing schedule for 40 consecutive hours. Ten subjects bicycled, 20 subjects controlled EEG activity during bedrest, and 10 subjects napped. Eight measures of addition, auditory vigilance, mood, and oral temperature were obtained. The Bedrest group showed significant impairment on all eight measures, and thus, gave no support to the forced rest theory of sleep function. The exercise group was worse than the Nap and Bedrest groups for all measures. In spite of fragmented, reduced sleep (about 3.7 hours per 24 hours), the Nap group had no impairment on six of the measures. The results suggest that exercise increases the impairment due to sleep loss, and naps reduce or remove this impairment.
