Influence of dynamic hand-grip exercise on acetone in gas emanating from human skin.
This study investigated the effects of dynamic hand-grip exercise on skin-gas acetone concentration. The subjects for this experiment were seven healthy males. In the first experiment, to ascertain the reproducibility of the results for the skin-gas acetone concentration test, the skin gas was collected four times from one subject. In the second experiment, all subjects performed three different types of exercise (Exercises I-III) for a duration of 60 s. Exercise I was performed at 10 kg with one contraction every 3 s. Exercise II was 30 kg with one contraction every 3 s. Exercise III was 10 kg with one contraction per second. Acetone concentration was analyzed by gas chromatography. In the first experiment, reasonable reproducibility was obtained in measurements of skin-gas acetone concentration during the hand-grip exercise. In the second experiment, acetone concentration in skin gas during hand-grip exercise II was significantly higher than the basal level. Although skin-gas acetone levels increased in all subjects during exercises I and III, a significant difference was not found. No significant difference was found in skin-gas acetone concentration during dynamic hand-grip exercise among exercises I, II, and III. This study confirmed that skin-gas acetone levels increase during dynamic hand-grip exercise.
