Figure 2.

Mean ± SE fasting, postprandial, and during subsequent exercise glycemic and insulinemic responses following the ingestion of high glycemic index (HGI) and low glycemic index (LGI) meals on days 1 and 5. HGI postprandial glycemic response (**) at 30 min and insulinemic responses (*) at 30, 60, and 90 min are significantly higher than LGI response on days 1 and 5. The observed glycaemic response is significantly associated with the glycaemic index, study day and time of exercise. The inner figure represents the mean ± SE area under the glycemic (AUGC) and insulinemic (AUIC) response curves in the first and last day of each experimental session. HGI AUGC on days 1 and 5 is significantly higher than LGI AUGC (a, b). Day 5 HGI AUIC is significantly higher than day 1 LGI AUIC (c, d).
