The Effects of Short-Term Carbohydrate Overfeeding and Prior Exercise on Resting Metabolic Rate and Diet-Induced Thermogenesis

摘要: In 10 young, normal-weight subjects, the effects were investigated of carbohydrate overfeeding and prior glycogen-depleting exercise on resting metabolic rate (RMR) diet-induced thermogenesis (DIT). Subjects kept controlled diets in a crossover design for two periods 8 days, with 1-week interval between. During last 4 days each period, additional carbohydrates added to subjects' diet. The started at 15% excess energy requirements day 1 increased 60% 4. At beginning end periods, RMR DIT measured, respectively, 3.5 hours using ventilated hood system. one 8-day evenings before exchange measurements, subjects performed maximum work capacity test cycle ergometer, then cycled total approximately 80 minutes fixed percentages their capacity. Carbohydrate did not affect RMR, but significantly, average by 39%. Glycogen-depleting significantly by, average, 9% (P = .08), 23%. impact was less when administered, there no significant interaction effect or DIT. It is concluded that both an antecedent diet high may influence
