TEE = total energy expenditure, AEE = active energy expenditure, PAL = ratio of total energy expenditure to resting energy expenditure for entire day. PAI24 = physical activity averaged over entire day, PAIw = physical activity intensity averaged over waking part of day, BM = body mass; HRR= heart rate reserve.
*, ** and *** denote p < 0.05, 0.01 and 0.001 respectively compared with Normal BMI.
