Body temperature rhythm and control of the time of the best physical condition by performing physical labor

ABSTRACT

The initial examination of a male subject’s body temperature revealed that it was highest during the evening. Based on this observation, I measured grasping power, calculation speed, performance time on a light sensory task and body temperature, all of which were highest or best during the evening. The time of this subject’s best physical condition shifted from the evening to morning hours when the subject executed hard physical labor in the morning, and the shifted phase was maintained after the termination of the labor period.
