Description of the sample in terms of body composition, energy expenditure and physical activity.

Spearman correlation coefficients between total energy expenditure (TEE) and physical activity energy expenditure (PAEE) by doubly labeled water and physical activity by accelerometry and questionnaire.
Figure 1.
Total energy expenditure (TEE) by doubly labeled water (kcal/day) and accelerometry-based physical activity (counts).
The regression equation is TEE = 1221+ (0.0033 * counts), adjusted r2 = 0.31, p-value for accelerometry-based physical activity 0.002.
Figure 2.
Physical activity energy expenditure (PAEE) by doubly labeled water (kcal/day) and accelerometry-based physical activity (counts).
The regression equation is PAEE = −286+ (0.0027 * counts), adjusted r2 = 0.34, p-value for MVPA 0.002.
Figure 3.
Total energy expenditure (TEE) by doubly labeled water (kcal/day) and minutes per week spent on physical activity by questionnaire.
The regression equation is TEE = 2283+ (0.56 * minutes per week of physical activity), adjusted r2 = 0.20, p-value for physical activity 0.02.
Figure 4.
Physical activity energy expenditure (PAEE) by doubly labeled water (kcal/day) and minutes per week spent on physical activity by questionnaire.
The regression equation is PAEE = 637+ (0.39 * minutes per week of physical activity), adjusted r2 = 0.16, p-value for physical activity 0.03.
