"After exercise begins, however, sympathetic nervous system hormones inhibit GI impact on insulin release. Unless your caloric intake exceeds the maximum that the liver can return to the body in the form of glycogen (about 280 calories per hour) glycemic index is not a major factor in choosing energy sources. During exercise, it's a nutritional error to value GI above saccharide profile."
