Background: Postprandial hyperglycemia and glycemic fluctuations are significant cardiovascular disease risk factors for patients with type 2 diabetes. We investigated the effects of a single session of post-dinner moderate-intensity exercise on the postprandial glycemic response compared with a non-exercise condition in a study population of Chinese patients with type 2 diabetes. Material/Methods: This randomized crossover self-controlled pilot study involved 29 patients with type 2 diabetes who participated in post-dinner exercise days using non-exercise days as a control. The interstitial glucose level was monitored using a continuous glucose monitoring system, with a standardized diet and medication. For the non-exercise control days, patients pursued normal daily activities but refrained from unusual strenuous physical activity. On the exercise days, participants walked on a treadmill for 20 minutes after dinner, with a heart rate reserve of 40%. Results: Post-dinner moderate-intensity exercise reduced the 2-hour postprandial glucose spike, mean glucose level, and peak glucose level compared to the control condition. The cumulative glucose total area under the curve during 1-hour post-exercise was lower with exercise than under the control condition. The 12-hour standard deviation of blood glucose and the coefficient variation of glucose were significantly lower in the with exercise day compared to the control day, although the 12-hour mean amplitude of glycemic fluctuations did not reach statistical significance. No nocturnal hypoglycemia subsequently occurred on the exercise day. Conclusions: A short session of moderate-intensity post-dinner exercise can improve postprandial hyperglycemia and glycemic excursions in Chinese patients with type 2 diabetes, with no potential hypoglycemia risk at a later period.
