Introduction: Type 2 diabetes is a growing problem throughout the world. It is projected that the incidence rate of this disease will double by 2030. Along with diet and medication, exercise has been identified as an important component of diabetes management. Purpose: The purpose of this study is to determine which exercise intervention, intermittent or continuous, lowers post-prandial blood glucose and fasting glucose levels. Methods: Ten middle aged sedentary adults reported to the lab in a fasting state. Researchers measured body fat percentage, weight, fasting glucose, and 2 hr peak post-prandial glucose pre- and post-intervention. Post prandial glucose was measured using a continuous glucose monitoring system. The continuous exercise group exercised 30 minutes a day for seven days at 65% maximum heart rate, while the intermittent group will exercised for 10 minutes, three times a day, for one week at 65% maximum heart rate. Results: The measures studied were analyzed using a paired t-test. The data did not show significant difference between the intermittent and continuous exercise groups for body fat percentage, weight, fasting glucose, or post-prandial glucose. Conclusion: Consistent with prior published research, the results of this study show that there is no difference between intermittent exercise and continuous exercise and the effects on glucose levels. Key Words: Type 2 diabetes, glucose, continuous glucose monitoring system, post-prandial.
