| 内容記述 | Many fat burner supplements to promote lipolysis have recently appeared on the market. As one of the final products of lipolysis, acetone contained in exhaled air is expected to be an easy noninvasive indicator of lipolysis levels. We carried out experiments to demonstrate the effect of a fat burner supplement taken before exercise on breath acetone during and after the exercise. All subjects were healthy men (n=5) aged from 22 to 43 years. A bicycle ergometer was used for the exercise. For each subject, exercise intensity, determined by heart rate, was 40% and the total exercise duration was 90 minutes. To measure acetone levels breath air was sampled every 15 minutes using a collection bag, and to determine the respiratory quotient breath was sampled for one minute five times using a Douglas bag. The experiment was carried out two times for each subject on separate days. Subjects took the fat burner supplement 30 minutes before the exercise in one experiment and took nothing in the other experiment allowing comparative assessment of the effect of ingestion of the supplement. Both with and without the supplement, breath acetone did not increase during the exercise then significantly increased after completion. Contrary to our expectation, the increase after exercise was lower in the case of taking the fat burner supplement than in the case of taking nothing. Glucogenic amino acids such as ornithine and L-carnitine in the supplement may have suppressed the production of ketone bodies including acetone like sugar. The respiratory quotient increased to about 1 during exercise then decreased to about 0.7 after exercise in both cases. This may reflect the balance between sugar and fat energy sources. | |||||||||||||
