This study examined differences between
long-term exercising (LE) and long-term nonexercising (LNE) women
[ n = 24; age 56.4 ± 6.2 (SD) yr] for resting metabolic rate (RMR) and energy
expenditure in the free-living state by using doubly labeled water
(DLW). There was a statistically significant difference
( P = 0.0002) between the 12 LE
(94.85 ± 8.44 kJ · kg 1 · day 1 )
and 12 LNE (81.16 ± 6.62 kJ · kg 1 · day 1 )
for RMR, but this difference was only marginally significant ( P = 0.06) when the data (MJ/day) were
subjected to an analysis of covariance with fat-free mass as the
covariate. The DLW data indicated that the eight most active LE
(12.99 ± 3.58 MJ/day) expended significantly
( P = 0.01) more energy than did the
eight least active LNE (9.30 ± 1.15 MJ/day). Energy expenditures
ranged from 7.64 to 18.15 MJ/day, but there was no difference
( P = 0.96) between the LE and LNE in
energy expenditure during activity that was not designed to either
improve or maintain fitness. These cross-sectional data on 49- to
70-yr-old women therefore suggest that
1 ) aerobic-type training results in
a greater RMR per unit of body mass and also when statistical control
is exerted for the effect of the metabolically active fat-free mass,
2 ) there is a large range in the
energy intake necessary to maintain energy balance, and
3 ) aerobic training does not result
in a compensatory reduction in energy expenditure during the remainder
of the day.
