| Outline of Final Research Achievements |
The present study determined the effect of acute exercise on breath acetone concentration, carbohydrate and fat metabolism during post-exercise. The influence of different carbohydrate intake on breath acetone concentration was also evaluated. Consequently, carbohydrate restriction following high-intensity interval exercise and endurance exercise increased breath acetone concentration. Moreover, the findings suggest that time-course changes in breath acetone concentration during post-exercise reflect carbohydrate availability and recovery of endurance capacity.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の結果、短時間・高強度運動や長時間の持久性運動後に呼気中アセトン濃度の上昇することが明らかになった。このことは、運動に伴う脂質代謝の亢進を反映すると考えられる。呼気中アセトン濃度の評価には採血の必要がなく、簡易に実施することが可能である。今後は、呼気アセトン濃度を指標として、運動に伴う糖・脂質代謝の変化や疲労からの回復の程度を評価する試みが期待される。
