To examine metabolic interaction between meal and exercise, 10 men and 10 women completed three trials: (1) exercise (E), (2) consumption of a meal (M), and (3) consumption of a meal followed by exercise (M+E). All trials commenced after an overnight fast and were preceded by a rest period in which resting metabolic rate (RMR) was determined. The meal contained 721 kilocalories composed of 41%, 36%, and 23% of carbohydrate, lipids, and protein, respectively. Exercise protocol consisted of three continuous 10-minute cycling at 50%, 60%, and 70% VO2peak. Measurement began 60 min after the start of the meal and included VO2 that was used to determine meal-induced thermogenesis (MIT). VO2 was greater (p < .05) in M+E than in E at 50% and 60% VO2peak. MIT was higher (p < .05) during exercise at 50% VO2peak than at rest. It appears that postprandial exercise of mild intensities can potentiate MIT, thereby provoking a greater increase in energy expenditure.
