  • Cardiopulmonary measurements in subjects who underwent exercise testing. Data are presented as mean±SD.

  • HRmax, maximum heart rate; O2pulsemax, oxygen uptake per heartbeat at maximum exercise; RER, respiratory exchange ratio (VCO2/ VO2) at maximum exercise; RRmax, maximum respiratory rate; VCO2max, maximum carbon dioxide production; VEmax, maximum minute ventilation value; VO2max, maximum oxygen uptake; VO2max·kg, maximum oxygen uptake per kilogram of body weight; VTmax, maximum tidal volume; Wattsmax, maximum work stage completed in watts.
