 note = {This study was under-taken to elucidate the effects of overnight sleep deprivation on the physical composition of blood and to examine the inductive factors of cardiovascular disease. The subjects were healthy 24 men over 30 years old. They sat up all night with playing mahjong from Friday evening to Saturday morning, but they slept at Saturday night. For experimental group submaximal exercise was conducted using bicycle ergometer. In order to determine hematocrit, hemoglobin concentration, water volume in the blood, red blood cell and white blood cell before and after exercise, blood sample was drawn from antecubital vein 10 or 12 times for 3 days. It was observed in this study that: 1) Hematocrit increased after exercise, but it decreased gradually during the experimental periods. 2) Hemoglobin concentration, red blood cell, and white blood cell increased significantly after exercise as compared with those at rest. The effects of overnight sleep deprivation on those parameters were not recognized. 3) Water volume in the blood decreased after exercise and it had tendency to increase in the morning. However, obvious effects of overnight sleep deprivation could not be seen. From these results, it was suggested that effect of overnight sleep deprivation on hematocrit might have any influences on heart and/or cardiovascular functions.},
