P e a k V O 2 : peak oxygen cousumption; P e a k V O 2 %: the percentage of actual P e a k V O 2 in the predicted value; P o w e r m a x : maximal workload; AT: ventilatory anaerobic threshold; V O 2 A T : oxygen consumption at anaerobic threshold; tAT: time from beginning to anaerobic threshold; SBPrest: systolic blood pressure at rest; DBPrest: diastolic blood pressure at rest; HRrest: heart rate at rest; BMI: body mass index.
