| Outline of Final Research Achievements |
Considering of relationship between food and body temperature in cold environments, we investigated body temperatures when exposed to cold environments after taking test food at room temperature.
(Study 1: high-carbohydrate diet and high-fat diet)Ingestion of high-carbohydrate or high-fat diet before cold exposure was able to maintain high subjective temperature sensation at the fingertips and trunk, but could not maintain skin temperatures.
(Study 2: normal temperature and hot amazake) Drinking of hot amazake before cold exposure could maintain subjective temperature sensation, but not skin temperature. On the other hand, drinking the normal temperature amazake before cold exposure could also maintain the temperature sensation of body temperature.

| Academic Significance and Societal Importance of the Research Achievements |
本研究課題は，寒冷環境で行われることが多い，冬季スポーツ実施者に対する栄養サポートの質の向上を目指し，食品摂取と体温の関連を検証した。寒冷環境曝露前に軽食 (高炭水化物または高脂質) または甘酒 (常温または温) を摂取しても，体温(皮膚温)の保持には至らなかったが，体幹部分の主観的体温感覚を高く保持することができた。
暑熱対策に関する研究は多く実施されている中で，本研究は寒冷対策に主眼をおいて研究課題に取り組んだ点は新規性があり，冬季スポーツ実施者に対する栄養サポートの充実に寄与するものと考えられる。
