Outline of Final Research Achievements |
We investigated the effect of difference in interval of short time face cooling, face cooling temperature during 40 min cycling exercise in 35 degree of ambient temperature and 50% of relative humidity. Furthermore, we investigated the effect of difference in exercise intensity for face cooling-induced improvement of endurance exercise ability in hot environment. Rating of perceived exertion were lower in the trial with face cooling conducted at 2 min interval than the trial with face cooling conducted at 4 min interval and without face cooling. Moreover, rating of perceived exertion were lower in the trial with face cooling conducted at 0 degree than the trial with face cooling conducted at 20 degree and without face cooling. There were no effect of exercise intensity for face cooling-induced improvement of endurance exercise ability in hot environment.

Academic Significance and Societal Importance of the Research Achievements |
高温環境下における長時間の運動は,末梢および中枢性の要因を介して疲労感を誘発し,運動能力の著しい低下,ひいては熱中症を引き起こす。このような運動能力の低下は,スポーツの競技力や競技成績の低下に直結する。また,建設業や警備業といった屋外労働においても,高温環境下での作業(運動)が熱中症を引き起こす大きな要因となっており,毎年一定数の死者が報告されている。顔面冷却は持久的運動能力の改善効果があることが明らかにされているが,その最適な方法については充分に検証されていない。高温環境下における運動能力の低下や熱中症を予防するための最適な顔面冷却の方法を見出すことは,社会的重要性が高いといえる。
