The data presented here suggest that metabolic responses to steady-state aerobic exercise are somewhat resistant to short-term changes in dietary carbohydrate (CHO) intake within the 5–6.5 g CHO·kg −1 ·day −1 [46–61% energy intake (EI)] range. In contrast, reduction in short-term dietary CHO intake to ∼2.4 g CHO·kg −1 ·day −1 (21% EI) evoked clear changes indicative of increased fat and decreased CHO metabolism during exercise.
