Age-Related Changes in Body Composition and Energy Metabolism

Abstract

Physical rehabilitation is fundamental in the elderly to contrast mobility impairment and disability but needs to be adapted to each patient’s features. Aging coincides with physiological changes in body composition and energy metabolism, in terms of resting energy expenditure and maximal aerobic capacity. These changes may be exacerbated by pathological conditions, often making it necessary to provide older subjects with rehabilitation care. This chapter outlines the main physiological changes in body composition and energy metabolism that can influence rehabilitation programs for the elderly.
