  • BDC calorie prescription, energy intake suggested in run-in phase. PTDC calorie prescription, energy intake suggested after run-in phase.

  • BDC calorie intake, energy intake deduced by food diaries in run-in phase. PTDC calorie Intake, energy intake deduced by food diaries after run-in phase.

  • Statistically significant values are in bold.

  • BDC, baseline data collection; CRF, cardiorespiratory fitness; GLM, general linear model; HIIT, high-intensity interval training; MD, median; MICT, moderate intensity continuous training; PTDC, post training data collection; VO2peak, peak oxygen uptake.
