Could someone briefly explain these findings below and why they occur?

The previously mentioned study by Foster et al. (1979) compared milk, which contains a mix of macronutrients, to glucose or water fed prior to exercise. The glycemic response to milk ingestion was less than that of glucose prior to exercise. Although the blood glucose concentration dropped at the start of exercise after milk ingestion, it later rose above that observed during the glucose trial. Serum fatty acid concentration during exercise was higher for milk (the lower glycemic index food) than for glucose. Performance after milk ingestion was improved relative to the glucose trial but was not superior to the control trial.

What is the overall summary of this paragraph? Do you think that the structure of the two components of starch has any thing to do with the study results? Why? Why not?

Guezennec et al. (1993) studied the difference in carbohydrate oxidation during exercise when amylose and amylopectin were consumed prior to exercise. Amylopectin was oxidized more quickly during exercise than was the amylose. Goodpaster et al. (1996) tested whether high amylose or high amylopectin foods fed prior to endurance exercise had different effects on metabolism or performance when compared to placebo or glucose feedings. A lower glycemic response was seen for both starches compared to glucose during the 30 min prior to exercise. However, in contrast to the results of Guezennec et al. (1993), the starches did not differ from one another in their glycemic responses in this pre-exercise period. Furthermore, all carbohydrate treatments increased the reliance on carbohydrate as a fuel during exercise. When compared to the placebo, the high-amylopectin starch was as effective as the glucose feeding in enhancing endurance performance but, in spite of similar glycemic effects of the two starches, the increased amount of work done during the 90 min performance test when the high-amylose starch was consumed was not statistically significant from the placebo. The authors felt that the lower digestibility of the high-amylose starch contributed to its reduced benefit on exercise performance. This study did not support a benefit of a lower glycemic food, i.e., starch, over a higher glycemic food (glucose) fed prior to exercise.
