  1. BMI body mass index, EAT/kg exercise-related activity thermogenesis/kg body weight, MET metabolic equivalent, n number of participants, NEAT/kg non-exercise activity thermogenesis/kg body weight, Ns not significant, SD standard deviation, *: P < 0.05
  2. Mean and standard deviation are given for parametric data, median and quartiles are given for non-parametric data. Two-tailed student t-tests for parametric data and Mann–Whitney-U-tests for non-parametric data were used
