1Values are means ± SEMs, n = 22 (n = 11 NW and n = 11 OW/OB subjects). *,***Significantly different from NW by unpaired t test, *P < 0.05, ***P < 0.001. bpm, beats per minute; HREX, average heart rate achieved during high-energy exercise sessions from 10 to 43 min; HRmax, maximum average heart rate achieved at the screening; NW, normal weight; OW/OB, overweight/obese; VET, ventilation threshold; VO2peak, maximum oxygen consumption.
