Metabolic adaptation
The relative contributions of carbohydrate and lipid oxidation to total energy expenditure were different only during the first 30 min of exercise with elevated FFA levels.
Practitioners should note that the impact of elevated FFA on substrate utilization is time-dependent during prolonged exercise.

the relative contributions of carbohydrate (49 +/- 4 vs. 50 +/- 4%) or lipid (49 +/- 4 vs. 47 +/- 6%) oxidation to the total energy expenditure were different only during the first 30 min of exercise.
