Separate and sequential effects of exercise and meal ingestion on energy expenditure. 1991

Northern Illinois University, De Kalb.

The present study was undertaken to determine whether or not untrained, non-obese college-aged females (n = 10) would exhibit a greater thermic response when exercise (E) (treadmill walking at 56% VO2max) preceded a meal (F) [3,846 kJ (920 kcal), 60% carbohydrate, 25% fat, and 15% protein] (EF) compared with exercise only (ENF) or a meal alone (NEF). A protocol in which neither exercise nor food (NENF) was present served as a baseline. Energy expenditure during 60 min of recovery increased 21.5% for the NEF condition, did not change in the ENF condition, and increased 20% in the EF condition over the corresponding resting metabolic rate. It was concluded that there was no interactive thermic effect from the exercise food sequence above the thermic effect of the meal alone.

UI	MeSH Term	Description	Entries
D010101	Oxygen Consumption	The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D001481	Basal Metabolism	Metabolism (e.g., heat production) of an organism in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the end products of oxidation within the organism or from the amount of oxygen utilized.

D015444	Exercise	Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.
