| Research Abstract |
This study could not reveal the effective factors on threshold temperatures at the start for sweating and heat production. However, this study showed that maximum oxygen uptake, daily activity, and vascular function affected to physiological responses to heat stimuli before sweating and to cold stimuli before increasing of thermogenesis. Also, this study showed that basal metabolic rate, which was influenced by food intake and air temperature, affected to the starting time for increasing metabolism during cold exposure.
