Outline of Final Research Achievements

The present study aimed to develop the optimal exercise and nutrition formulas for obtaining heat tolerance in ovariectomized rats. As for the exercise training, there was no difference in the increase in body temperature under heat depending on whether the ovaries were removed or not. For the nutritional prescription, genistein, a type of soy isoflavone, contributed to the decrease in body temperature in the ovariectomized rats under normal conditions. In addition, genistein intake tended to suppress the increase in body temperature in the ovariectomized rats under a hot environment.

Academic Significance and Societal Importance of the Research Achievements

閉経女性の健康問題に関しては、骨粗鬆症に注目が集まり、体温調節異常に関する研究が遅れている。地球温暖化やヒートアイランド現象が進み、かつ日本女性の平均寿命が延伸している現代において、閉経後に暑熱環境に晒される期間が増え、その分熱中症リスクも高い。本研究は、閉経女性の高い熱中症リスクに対し、その対処法に着目している点で社会的意義が高い。
