Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 55 years
- All sexes
- Healthy volunteers accepted
- Adult
Who may be able to join
- Female or Male
- 18-55 years of age
- BMI = 25-29.9 kg/m2
- Ability to provide informed consent.
- Ability to provide consent from their personal physician to participate in this study.
Who cannot join
- Reporting regular exercise participation of at least 20 minutes per day on at least 3 days per week during the previous six months. (This study is designed to recruit relatively sedentary adults.)
- Diabetes, hypothyroidism, or other medical conditions which would affect energy metabolism.
- Women who are currently pregnant, pregnant within the previous six months, or planning on becoming pregnant within the next 12 months. (Pregnancy during initial screening will be based on self-report and will be included on the detailed medical history that is completed by subjects. However, this will be confirmed with the urine pregnancy test that will be conducted prior to the baseline DEXA.)
- Non-medicated resting systolic blood pressure >160 mmHg or non-medicated resting diastolic blood pressure >100 mmHg, or taking medication that would affect blood pressure.
- Taking medication that would affect resting heart rate or the heart rate response during exercise (e.g., beta blockade).
- Arrhythmia on resting or exercise electrocardiogram that would indicate that vigorous exercise was contraindicated.
- History of myocardial infarction or valvular disease.
- History of orthopedic complications that would prevent optimal participation in the exercise component (e.g., heel spurs, severe arthritis).

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing behavioral exercise intervention in people with Weight Loss, run by University of Pittsburgh at 1 site in United States.
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 5 inclusion and 8 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 15 Sep 2005. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
body weight. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00177502, 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 15 Sep 2005.
