Smith, D. A., J. Dollman, R. T. Withers, M. Brinkman, J. P. Keeves, and D. G. Clark. Relationship between maximum aerobic power and resting metabolic rate in young adult women.J. Appl. Physiol. 82(1): 156–163, 1997.—The literature is inconclusive as to the chronic effect of aerobic exercise on resting metabolic rate (RMR), and furthermore there is a scarcity of data on young women. Thirty-four young women exhibiting a wide range of aerobic fitness [maximum aerobic power (V˙o 2 max) = 32.3–64.8 ml ⋅ kg−1 ⋅ min−1] were accordingly measured for RMR by the Douglas bag method, treadmillV˙o 2 max, and fat-free mass (FFM) by using Siri’s three-compartment model. The interclass correlation (n = 34) between RMR (kJ/h) and V˙o 2 max(ml ⋅ kg−1 ⋅ min−1) was significant (r = 0.39,P < 0.05). However, this relationship lost statistical significance when RMR was indexed to FFM and when partial correlation analysis was used to control for FFM differences. Furthermore, multiple linear-regression analysis indicated that onl...
