T1: start of study, T2: end of study. VO₂ predicted T1, VO₂ predicted at start of study; % VO₂ predicted T1, % VO₂ predicted at start of study; VO₂ peak (oxygen uptake at peak effort peak), VCO₂ (carbon dioxide output), METS (metabolic equivalent), RCP (respiratory compensation point), VE (minute ventilation) expressed in L/min, and HR max (heart rate maximum) expressed in beats/minute. Significant results (p ≤ 0.05) are represented in bold.
