-1 hour of 50% VO2max exercise immediately preceding an OGTT increases the rate of glucose appearance of both endogenous (in first 10-30 min of OGTT) and exogenous glucose (starting at 40-50 min of OGTT) in those with normal glucose tolerance, impaired glucose tolerance, and type 2 diabetes. The Rd and the MCR (Rd/glucose concentration) during the OGTT were all elevated by the preceding exercise. However, postprandial glucose concentration was not improved by the exercise in the IGT and those with type 2 diabetes and was worsened in those with normal glucose tolerance.

Effects of moderate and subsequent progressive weight loss on metabolic function and adipose tissue biology in humans with obesity. Cell Metab 23, 591–601.

-Most importantly, this study demonstrates the difficulty in improving postprandial glucose tolerance even with a weight loss that improved insulin sensitivity of muscle and liver during a euglycemic-hyperinsulinemic clamp after 2.5 hours. Table 4 shows that progressive weight loss of 5, 11, and 16% by a low calorie diet did not significantly change OGTT glucose AUC, nor 2 hr glucose concentration in obese participants who had evidence of insulin-resistant glucose metabolism. Furthermore, insulin AUC was not significantly lowered by 5 or 11% weight loss but was lowered by 23% (P<0.05) with 16% weight loss. Table 3 shows that there was not a significant interaction between the change in the glucose AUC, 2 hr glucose, insulin AUC in the weight maintenance group and the 5% weight loss group. All three levels of weight loss significantly improved hyperinsulinemic euglycemic clamp determined peripheral and hepatic insulin action assessed at 2.5 to 3 hrs of steady insulin infusion.

-Postprandial glucose was elevated if starting the OGTT 30 min after 55 minutes of 71% VO2max exercise compared to a preceding resting condition. The preceding exercise increased glucose iAUC by 71% due at least in part to an elevated rate of appearance of glucose from both endogenous (significant at 15-30 min of the OGTT) and exogenous ingested glucose. While glucose rate of disappearance was elevated during the OGTT post exercise, when divided by the prevailing glucose concentrations (i.e., MCR) there were no differences between the two conditions nor was there a difference in insulin concentrations.

Effects of exercise training alone vs a combined exercise and nutritional lifestyle intervention on glucose homeostasis in prediabetic individuals: a randomised controlled trial. Diabetologia 59, 2088–2098.

-The consensus panel recommended amount and high amount of moderate intensity exercise training significantly reduced OGTT glucose iAUC by 16 and 20% and high amount of vigorous exercise did not improve glucose iAUC (these three doses did not impact fasting glucose). Recommended amount of moderate intensity exercise training combined with dietary restriction and a 7% weight loss significantly reduced glucose iAUC by 17%. 2 hr glucose was not significantly impacted by recommended amount of either moderate or vigorous exercise training, but was lowered by 13 mg/dL by a high amount of moderate exercise training and by 23 mg/dL from combined 7% weight loss plus the recommended amount of moderate intensity exercise training.
