About this study
The study will compare the effects of High Intensity Interval Training (HIIT) with Moderate Intensity Continuous Training (CMIT) as part of a lifestyle intervention program on BMI change in adolescents age 12-16 with obesity.
Read the detailed description
Adolescents will be randomized to a 12-week lifestyle intervention including behavioral and dietary interventions, and one of two exercise training conditions, HIIT or CMIT). Adolescents in the HIIT treatment will participate in treadmill exercise in 1-minute intervals of challenging intensities with recovery periods in between, gradually increasing the number of intervals over the course of the study. Adolescents in the CMIT treatment will participate in a constant moderate intensity treadmill exercise, gradually increasing the duration of the exercise over the course of the study.
Both parents and teens will have height and weight measurements taken, complete behavior questionnaires and wear an activity monitor for one week at baseline, 12 weeks and 16 weeks.
Adolescents will have a physical exam by a study medical provider before starting the intervention. Adolescents will also have blood work, an oral glucose tolerance test, an electrocardiogram, body composition measurements and a maximal graded exercise test done at baseline, and again at one or more time points. Adolescents will also complete a detailed food log at those time points.
Adolescents will exercise at the study gym 3 evenings a week for 12 weeks. On one of those evenings teens will also attend a 60-minute individual behavioral weight management session. Nine of these are with a behavior coach, and 3 with a dietitian. Parents will also attend one introductory session with the behavior coach, join the teen for the 3 sessions with the dietitian, and review adolescent individual goals and identify parent support goals at the end of each behavior session.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
High-Intensity Interval TrainingBehavioural
Participants assigned to HIIT will participate in treadmill exercise in intervals consisting of 1 minute intervals of challenging intensities with recovery periods in between, gradually increasing the number of intervals over the course of the study.
Moderate-Intensity Continuous TrainingBehavioural
Participants assigned to CMIT will participate in constant moderate intensity treadmill exercise, gradually increasing the duration of the exercise over the course of the study.

Questions about this trial
What is this clinical trial studying?
A study testing High-Intensity Interval Training and Moderate-Intensity Continuous Training in people with Pediatric Obesity and Adolescent Obesity, run by Virginia Commonwealth University 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 3 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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.
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?
Cardiorespiratory fitness (time frame: 12 weeks). 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 8 Apr 2021; AzTrials last refreshed its copy on 7 Nov 2026.
