L Vaughan, F Zurlo, E Ravussin - The American journal of clinical nutrition, 1991 - Elsevier
Whether sedentary energy expenditure is normal or lower in elderly people has not yet been
clearly established. Twenty-four-hour energy expenditure (24EE) and its different
components were measured by use of a respiratory chamber in elderly (17 male, 21 female;
71±6 y, x̄±SD; 71.2±13.5 kg; 32±8% fat) and young (33 male, 31 female; 24±4 y; 84.5±23.1
kg; 25±13% fat) subjects. The elderly subjects had lower mean height (P< 0.001), weight (P<
0.01), and fat-free mass (P< 0.001) but higher percent body fat (P< 0.01) than did the young …
