Abstract:

Glucose disposal ie. insulin sensitivity is impaired in sedentary individuals, impaired glucose tolerance, and type 2 diabetes. Exercise increases carbohydrate oxidation during and glycogen storage after exercise in these populations. These effects are short-lived and are prior to changes in enzyme activities. Fat oxidation is relatively minor on a gram basis compared to carbohydrate oxidation at an intensity of 65% of VO2 peak. From deductive reasoning this leads to the conclusion that carbohydrate oxidation during exercise and rest is elevated above carbohydrate ingestion and that this muscle and liver “sink” leads to improved glucose disposal/ insulin sensitivity. In this editorial I propose guidelines for exercise duration/intensity and carbohydrate ingestion to realize these effects and explain the calculations that resulted in these conclusions.
