Energy balance

Total carbohydrate oxidation during steady-state exercise is similar regardless of the glycemic index of the preexercise meal.

This indicates that the type of carbohydrate consumed before exercise may not significantly impact energy utilization during prolonged cycling.

StrongSupportsmedium confidence
both total CHO oxidation for HGI, LGI, and Con trials, respectively, during steady-state exercise [403 +/- 16, 376 +/- 29, and 373 +/- 24 (SE) g/2 h] and oxidation of the ingested CHO (65 +/- 6, 57 +/- 6, and 63 +/- 5 g/2 h) were similar.
