Seven nonobese adult females (40 +/- 8 years) were studied in a room calorimeter on a day that resistance exercise (REX) was performed (4 sets of 10 exercises) and on a nonexercise control day (CON). Twenty-four-hour energy expenditure (EE) on the REX day (mean +/- SD, 2,328 +/- 327 kcal.d(-1)) was greater than CON (2,001 +/- 369 kcal.d(-1), p < 0.001). The net increase in EE during and immediately after (30 minutes) exercise represented 76 +/- 12% of the total increase in 24-hour EE. Twenty four-hour RQ on the REX day (0.86 +/- 0.06) did not differ from CON (0.87 +/- 0.02). Twenty four-hour carbohydrate oxidation was elevated on the REX day, but 24-hour fat and protein oxidation were not different. Thus, in women, the increase in EE due to resistance exercise is largely seen during and immediately after the exercise. The increased energy demand is met by increased carbohydrate oxidation, with no increase in 24-hour fat oxidation.

Resistance and aerobic exercise have similar effects on 24-h nutrient oxidation.

Med Sci Sports Exerc 2002 Nov;34(11):1793-800

Center for Human Nutrition, University of Colorado Health Sciences Center, Denver, 80262, USA.

Background: Whether resistance exercise is as effective as aerobic exercise for body-weight management is debated.

Purpose: To compare 24-h energy expenditure (EE) and macronutrient oxidation elicited by comparable bouts of stationary cycling (BK) and weightlifting (WTS).

Methods: 24-h EE and macronutrient oxidation were measured in 10 nonobese male subjects on three occasions using whole-room indirect calorimetry. Read More

Regulation of macronutrient balance in healthy young and older men.

Int J Obes Relat Metab Disord 2001 Oct;25(10):1497-502

Department of Health and Exercise Science, Colorado State University, Fort Collins, Colorado, USA.

Objective: To determine the influence of age on the ability to adjust macronutrient oxidation to changes in diet composition. Our hypothesis was that the ability to adjust macronutrient oxidation to changes in diet composition would be impaired with age.

Design: Cross-sectional, randomized to three different isocaloric diets containing a constant percentage protein but varying in percentage fat and percentage carbohydrate: mixed diet (M; 15/30/55); high-fat diet (HF; 15/60/25), and high-carbohydrate (HC; 15/15/70). Read More

Center for Designing Foods to Improve Nutrition, Department of Food Science and Human Nutrition, Iowa State University, Ames, IA 50011, USA.

Background: Glutamine interacts with insulin-mediated glucose disposal, which is a component of the increase in energy expenditure (EE) after a meal. The study aim was to examine if glutamine supplementation alters postmeal nutrient oxidation.

Methods: Ten healthy young adults consumed a mixed meal (6. Read More
