Optimal Exercise Regimens for Persons at Increased Risk
A Phase 2 study testing exercise in people with Cardiovascular Diseases and Coronary Disease, run by National Heart, Lung, and Blood Institute (NHLBI).
Trial summary
To assess exercise training adherence and compliance over two years in subjects who were at relatively high risk for coronary artery disease. Also, to test strategies for improving adherence and compliance and to assess the effect of exercise training. Read more about this study

About this study
To assess exercise training adherence and compliance over two years in subjects who were at relatively high risk for coronary artery disease. Also, to test strategies for improving adherence and compliance and to assess the effect of exercise training.
Read the detailed description
BACKGROUND:
Regular physical exercise is associated with lower coronary heart disease mortality, favorably affects coronary risk factors, and increases cardiovascular functional capacity. Fewer than one-third of Americans engage in regular physical exercise and only 20 percent of men and 10 percent of women over age 45 do so. This is largely because effective strategies for increasing the exercise habit in a broadly-based segment of Americans have not been developed. This study applied physiological and behavioral knowledge derived in numerous laboratories over the past 10-15 years to a clinical setting.
DESIGN NARRATIVE:
Following stratification by gender and cigarette smoking status, subjects were randomized to one of four groups: home exercise of moderate intensity which was individually monitored; home exercise of high intensity which was individually monitored; exercise of high intensity which was group supervised; and a no program control group. The intervention program was conducted for one year followed by a one-year maintenance program. Main outcome measures included treadmill exercise test performance, exercise participation rates, and heart disease risk factors. Variables measured over two years included plasma lipids, lipoproteins, apoproteins, lipase activity, glucose and insulin, sex hormones, cardiovascular reactivity to psychological stress, cigarette smoking, nutrient intake, psychological status, and cardiovascular functional capacity.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing exercise in people with Cardiovascular Diseases and Coronary Disease, run by National Heart, Lung, and Blood Institute (NHLBI).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 24 Jun 2005. 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00000523, which also lists 1 linked publication.
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 24 Jun 2005.
