This report describes the effect of acetic acid on the glucose metabolism after exercise for 30 min. at 60%HRmax. The investigation was carried out in five healthy university students. The students drank one of the following four test solutions twice, immediately after and 30 min. after exercise. Each ingestion volume was 250ml at a time. The test solutions prepared were: 1) distilled water (group W), 2) 6% glucose solution (group G), 3) 0.5% citric acid + 6% glucose solution (group C), and 4) 0.5% acetic acid + 6% glucose solution (group V). Six blood samples (before exercise and at 0,15, 30, 60 and 120 min. after exercise) were drawn. No significant increase in serum lactic acid concentration was observed in all groups immediately after exercise, however group G showed a significant increase at 60 min. after exercise (p<0.05). Blood glucose increased significantly in three groups (G,C and V) after drinking (p<0.05), however the suppression in the increment rate was observed in both groups, C and V. The same tendency was observed in insulin. As for free fatty acids, only group W showed a significant increase after exercise (p<0.05), to the contrary other three groups indicated decreasing tendency. No significant difference in concentration of serum ketone body was shown in all groups. Group C and V showed almost the same tendency throughout the study. The metabolic pathways of citric acid and acetic acid to human body is still uncertain, therefore it is difficult to explain the correlation of the findings obtained from this research. These findings showed that citric acid and acetic acid have almost the same metabolic effects to human body, suggesting the possibility of acetic acid for the use as a component of sports drink.}, pages = {59--66}, title = {中等度運動回復期における水分補給の効果 : 純水、糖、クエン酸、食酢の比較}, volume = {20}, year = {1997} }
