| Research Abstract |
The short time sleep after the lunch (i.e. nap, 10-20 min shallow sleep) is well known to prevent the declines of work efficiency and arousal level in office workers and drivers. In this study, we examined the effect(s) of short time sleep on the exercise performance and its related basic physiological functions and capacities such as visual acuity, arousal level of the brain, reaction time, nociceptive threshold of the skin, taste sensation, and subjective symptom. The results from the basic and practical experiments indicated that; 1) the nap (less than 20 min with stages 1 and 2) showed some positive effects on information processing system in the brain and visual acuity, and 2) a more long time and deep sleep (i.e. approximately one hour including stages 3 and 4), rather than rest and/or even nap, might have the positive effects on short-term maximal anaerobic power (estimated by the standard test using by the cycle ergometer) and kinetic vision.
