TABLE 2.
Measures of energy expenditure overall and by physical activity category1
| Total (n = 161) | Sedentary/low active (n = 90) | Active/very active (n = 71) | P | |
| TEEDLW (kcal/d) | 1959 ± 260 | 1851 ± 213 | 2097 ± 249 | <0.001 |
| EERDRI (kcal/d) | 1838 ± 229 | 1689 ± 150 | 2028 ± 161 | <0.01 |
| RMR (kcal/d) | 1225 ± 136 | 1231 ± 136 | 1216 ± 137 | 0.48 |

All values are means ± SDs. P values for differences between physical activity category groups were determined by using an independent samples t test. EERDRI, estimated energy requirement determined by using Dietary Reference Intake equations; RMR, resting metabolic rate; TEEDLW, total energy expenditure measured by using doubly labeled water.
