About this study
Official title: Continuous vs. Interval Exercise Training on Oxygen Uptake Efficiency Slope in Patients With Coronary Artery Disease
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.
Read the detailed 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Aerobic exercise trainingOther
Also called continuos training, interval training
The continuous exercise training was performed on a treadmill with a 50-minutes duration and intensity at ventilatory anaerobic threshold.
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

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Aerobic exercise training in people with Coronary Artery Disease, run by Hospital TotalCor.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The oxygen uptake efficiency slope (time frame: up to 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2015.
