Results for the associations between VO2max and EE measures using general linear models.

Dependent variables β Standardized β P- value 95% confidence limits R2 for model
Resting metabolic rate (kcal/day, N=162) 68.2 ± 25.0 0.214 0.007 18.8–117.7 0.780
Sleep metabolic rate (kcal/day, N=202) 27.4 ± 24.3 0.081 >0.2 −20.6–75.3 0.753
Awake and fed thermogenesis (kcal, N=165) 66.1 ± 26.9 0.194 0.015 13.0–119.2 0.214
Spontaneous physical activity (%, N=173) −0.11± 0.55 −0.016 >0.8 −1.2–1.0 0.127
24-h energy expenditure (kcal, N=207) 62.2 ± 29.6 0.147 <0.05 3.9–120.5 0.807
24-h RQ (N=207) −0.003 ± 0.003 −0.055 >0.4 −0.009–0.004 0.225

B, Standardized β, P-value, and 95% confidence limits represent the results for VO2max as independent variable of general linear models. Other covariates as independent variables for all EE measures were fat-free mass, fat mass, age, sex, and race, and for 24-hRQ were %fat mass, energy balance, age, sex, and race.
