Mean respiratory exchange ratio (RER) during the final minute of all five exercise bouts at ~50, 60, 70, 80, and 90% of $\stackrel{\bullet }{\text{V}}{\text{O}}_{2\text{max}}$ and the graded exercise test (GXT) in well-trained (A) and recreationally trained (B). High, pre-event meal with high carbohydrate content; low, pre-event meal with low carbohydrate content; fasted, test in fasted state. *significant effect of pre-event meals after a follow-up test with both groups included (p ≤ 0.05).
