Outline of Final Research Achievements

The study aimed clarify the effects of beverage intake before the exercise on the dehydration and exercise performance. The results indicate that pre-exercise beverage intake(400ml) is associated with a reduced risk of dehydration. Next, we focused on neutral temperature beverages and examined the effects of different timing of intake on exercise performance (endurance exercise capacity) in a hot environment. Endurance exercise capacity was not affected by the timing of intake of neutral temperature beverages.

Academic Significance and Societal Importance of the Research Achievements

運動時は運動中の飲料摂取だけではなく、運動前から摂取を実施する必要があるが、運動前の飲料摂取の重要性についての認知度は低いものと考える。本研究では、少量（400ml）の運動前飲料摂取に着目した結果、脱水リスクの軽減に繋がることが明らかとなった。このことは、日常生活からアスリートまで多くの場面において活用することができ、安全な運動環境の周知に寄与するものと考える。
