| Outline of Final Research Achievements |
The purpose of this study was to examine individual differences and their influence factors from the patterns of cold-induced non-shivering and shivering thermogenesis. Adult males participated to this study, and they exposed to cold environment which air temperature was falling from 28 degrees to 15 or 5 degrees for 90 min. Measurements were the rectal and skin temperatures, expired gas analysis value, electromyogram(EMG), etc during cold exposure. The cold-induced thermogenesis was quantified from oxygen intake and carbon dioxide emissions obtained from exhalation gas analysis, and was divided into non-shivering and shivering thermogenesis by EMG. From the pattern of thermogenic reaction, it became possible to divide into three types, which were non-shivering thermogenesis by brown adipose tissue, non-shivering by other effector than brown adipose tissue, and shivering thermogenesis type. It was possible to evaluate physiological polymorphism in cold - induced heat production.
