RESTING AND EXERCISE METABOLISM FOLLOWING LONG-TERM EXERCISE

Abstract

The effects of exercise on the components of energy expenditure remain controversial. This is due to the many study designs and exercise protocols employed by investigators, and is due to the dynamic nature of the interaction of the components of energy expenditure. Although cross-sectional studies provide insightful information regarding the effects of trained vs non-trained individuals, the more powerful study design may be longitudinal studies using previously sedentary individuals who undergo longterm training. This symposium will focus on the effects of chronic aerobic and resistance training on total daily energy expenditure and its components. Studies using state-of-the-art methods such as doubly labeled water and whole-room indirect calorimetry will be presented as well as studies using complete energy balance techniques. Current information on the effects of chronic exercise on resting metabolism, EPOC, and the “trained state” will be presented with implications for the regulation of body weight.
