Abstract

This study determined whether performing a single moderate- or vigorous-intensity exercise bout impacts daily physical activity energy expenditure PAEE, by accelerometer. Overweight-obese postmenopausal women underwent a 5-month caloric restriction and moderate- or vigorous-intensity center-based aerobic exercise intervention. During the last month of intervention, in women performing moderate-intensity exercise, PAEE on days with exercise kcal·d

was higher than on days without exercise kcal·d

; however, the difference kcal·d

was much lower than the energy expended during exercise. In women performing vigorous-intensity exercise, PAEE on days with exercise kcal·d

was lower than on days without exercise kcal·d

. Thus, women expended more energy on physical activities outside of prescribed exercise on days they did NOT perform center-based exercise, especially if the prescribed exercise was of a higher intensity.
