Summary

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.

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.

Interventions

Type	Name	Description
BEHAVIORAL	High-Intensity Interval Training	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.
BEHAVIORAL	Moderate-Intensity Continuous Training	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.
