Data are presented as mean (± standard deviation) for normally distributed variables and as median (inter-quartile range) for non-normally distributed variables and as frequency (percentage) for categorical variables. Abbreviations: RMR resting metabolic rate, RQ respiratory quotient, VCO2 carbon dioxide produced, VO2 oxygen consumed, LTPAQ leisure time physical activity questionnaire, AMI activity metabolic index, PA physical activity.

a = significantly different from Group 1; b = significantly different from Group 2; c = significantly different from Group 3.
