Data are expressed as mean (SD); : baseline vs. 6-month posttraining follow-up; a: Group A vs. B. : maximum diastolic blood pressure; METs: workload; : maximum systolic blood pressure; VE: ventilation; VE/VCO2: slope of expired minute ventilation for carbon dioxide; VCO2: volume of carbon dioxide after exhalation per minute; VO2 peak AT: peak oxygen consumption at AT; VO2 peak: peak oxygen consumption.
