Study Overview
Brief Summary
The purpose of this study is to examine the effect of a home-based high intensity interval training intervention on exercise among low active adults (defined as engaging in exercise 90 minutes or less per week). Participants will be randomly assigned to a HIIT-based intervention or a wait-list control each lasting 12 weeks (participants in the wait-list control condition will have the option of receiving the HIIT intervention following the 12 weeks).
Detailed Description
The intervention will be a 12-week high intensity interval training workout that will consist of home-based exercise sessions prescribed by the exercise counselor. The exercise sessions will be based on exercises the participant can confidentially engage in (regular push-ups vs. knee push-ups vs. wall push-ups). The goal will be to engage in three exercise sessions per week. The participants will receive weekly telephone calls during the first month and bi-weekly calls during months 2 and 3. The exercise counselor will also engage in dialogue that will motivate the participant to exercise.

Arms & Interventions
High Intensity Interval Training
The exercise group will participate in a home and telephone-based program consisting of a 12-week high intensity interval training workout (HIIT). The home-based exercise sessions will be prescribed by the program exercise counselor, with a goal to exercise three times per week. The program will be tailored to meet specific fitness and strength needs of the participant. The participant will receive weekly telephone calls during the first month and bi-weekly calls during months 2 and 3. At 12 weeks, participants in both the exercise and wait-list control group will complete online questionnaires. The ActiGraph will be returned to the University of Minnesota research staff via a pre-paid postage envelope.
Intervention: High Intensity Interval Training (Behavioral)
Wait-List Control Group
Participants in the wait-list control condition will have the option of receiving the exercise intervention program after completion of the final assessment.
Outcomes
Primary Outcomes
Exercise minutes per week
Time Frame: Change from Baseline to 12 weeks
Exercise minutes per week as assessed by an accelerometer for one week at baseline and 12 weeks. Higher reported minutes per week indicates a higher level of physical activity.
Secondary Outcomes
- Physical Activity Self-efficacy Questionnaire(Change from Baseline to 12 weeks)
- Biometrics(Change from Baseline to 12 weeks)
- Social Support for Exercise Questionnaire(Change from Baseline to 12 weeks)
- Physical Activity Enjoyment Scale (PACES)(Change from Baseline to 12 weeks)
- Outcome Expectancies Questionnaire(Change from Baseline to 12 weeks)
