Effect of exercise on the blood biochemical parameters in healthy dogs under oral glucose tolerance test

Abstract

 Changes in blood glucose concentration due to exercise were reported to induce various side effects such as hypoglycemia and delayed digestion and absorption depending on timing of mealtime. Postprandial hypoglycemia has been reported in the dog during hunting, however, its mechanism is unknown. Therefore the purpose of this study was to evaluate blood biochemical parameters before and after oral glucose tolerance test（OGTT）in healthy 4 dogs. Exercise was performed after 30 minutes from the beginning of OGTT. The results suggested that exercise induce decreasing blood glucose and insulin concentrations after OGTT. As such, conditions with both hyperglycemia and hyperinsulinemia might have higher risk of lowering blood glucose concentratsons. Moreover, exercise in fasting state induced lipolysis.
 In the future, we should evaluate relationship between exercise and diet（include various nutrient component）, since OGTT was only performed in the present study.
