Values are given as the mean ± SE. O_2peak, peak aerobic capacity for walking; HR_rest ¹, heart rate at rest before starting the exercise for the O_2peak measurement; HR_peak, peak heart rate at O_2peak; O_2AT, anaerobic threshold for cycling; HR_rest ², heart rate at rest before starting the exercise for the O_2AT measurement; and HR_AT, heart rate at O_2AT. Significant differences compared to the value before training, *P<0.05 and **P<0.01.
