| Outline of Final Research Achievements |
Acetone is produced in lipolysis, and exhausted with exhaled air and urine. Therefore, acetone contained in the exhaled air is expected to be an indicator of lipolysis in our body. The purpose of this study was to examine the effect of various factors such as meal intake on the expired acetone and blood components during and after exercise by several exercise experiments.
In all conditions, expired acetone significantly increased during or after exercise compared to before exercise. Judging from variations in blood components, lipolysis and production of acetone in their bodies were promoted by exercise. However, the differences about variation in expired acetone were observed by several factors such as meal after exercise, exercise intensity, combination of different types of exercise.
In conclusion, acetone contained in the exhaled air might be useful as the indicator of lipolysis, if we adequately consider the conditions about exercise and meal.
