| Outline of Final Research Achievements |
We found that the elderly people with high endurance performance through long time marathon training compared to the young long-distance runners had similar or superior sweat gland function in exercise- and acetylcholine-induced sweating responses and sweat ion reabsorptive ability. It was suggested that the degree of sweat gland's improvement in the elderly runners was smaller on the lower limbs, at which the age-related decrements in sweat gland function occurs earlier. Similar improvement characteristics of the sweat gland function were observed in both sexes and the degree of improvement was almost equal between the elderly male and female runners. However, the elderly female runners maintained the female sweating characteristic that compensate lower sweat gland output in higher active sweat glands. Our findings in the present study can contribute to development of measures for preventing heat illness in the elderly.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，マラソンのような持久的運動レーニングを継続すれば，（１）少なくとも70歳前後の高齢者でも若者ランナーに匹敵する汗腺機能を保持できること，（２）汗腺機能のトレーニング効果は老化が早期に進行する身体部位（下肢）では小さいこと，（３）上記（１）（２）の汗腺機能特性には性差がないこと，をそれぞれ見出したことに学術的意義がある．これらの知見は，将来的にさらに増加することが予想される高齢者の熱中症を予防するために，高齢者に対し（可能ならばより早期から），持久的運動レーニングを奨励し，日常生活下で発汗する機会を増大させることがいかに重要であるかを示す大きな社会的意義がある．
