| Outline of Final Research Achievements |
Previous studies demonstrated that carbohydrate (CHO) feeding 30-45 min before exercise results in transient hypoglycemia shortly after onset of exercise. The purpose of this study was thus to directly compare the effects of fasting vs. feeding on plasma glucose kinetics following pre-exercise carbohydrate ingestion. This results show that, transient hypoglycemia shortly after onset of exercise may occur not only after an overnight fast, but also in the fed state. In addition, subjects with higher aerobic fitness and enhanced insulin secretory capacity seem to be more prone to transient hypoglycemia following pre-exercise carbohydrate ingestion under fed and fasted conditions, respectively.
