About

Thus, the purpose of the present study was to evaluate the effects of continuos exercise training (CET) and interval exercise trainining (IET) on oxygen uptake efficiency slope (OUES) in patients with coronary artery disease.

Full description

The oxygen uptake efficiency slope (OUES) is a submaximal index that incorporates cardiovascular, peripheral and pulmonary factors that determine ventilatory response to exercise. There is scarce information about the effects of the mode and intensity of exercise training on OUES in patients with coronary artery disease.

35 participants in 2 patient groups

Continuous exercise training

Experimental group

Description:

The continuous exercise training was performed on a treadmill with a 50-minutes duration and intensity at ventilatory anaerobic threshold.

Treatment:

Other: Aerobic exercise training

interval exercise training

Experimental group

Description:

The interval exercise training consisted of 7 sets of 3 minutes at respiratory compensation point and 7 sets of 3 minutes of exercise at moderate intensity corresponding to the ventilatory anaerobic threshold totaling 42 minutes

Treatment:

Other: Aerobic exercise training
