An interventional study of High Intensity Interval Training in Cardiovascular Diseases, sponsored by University of Minnesota. Completed at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-10-09.
Sponsored by University of Minnesota · Not applicable, Interventional, and Prevention
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).
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.

Exclusion Criteria:
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.
Behavioral: High Intensity Interval Training
Participants in the wait-list control condition will have the option of receiving the exercise intervention program after completion of the final assessment.
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.
Exercise minutes per week
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.
Time frame: Change from Baseline to 12 weeks
Biometrics
Body Mass Index will be calculated based on combining weight and height to report BMI as kg/m\*2. The higher the number (level) of BMI, indicative of higher weight to height ratio.
Time frame: Change from Baseline to 12 weeks
Social Support for Exercise Questionnaire
Assesses the degree to which the individuals has friends and family who support their exercise. Participants rate how often family member or friend expresses social support for physical activity with scale (0=none, 4=very often). Overall total score range 0- 104 with subscales for family (0-52) and friends (0-52).
Time frame: Change from Baseline to 12 weeks
Physical Activity Self-efficacy Questionnaire
Assesses the amount of confidence the individual has to engage in exercise. Five questions, responses are on a scale from 1- 5 with participants indicating how confident they are on that scale of engaging in exercise in that situation (1=not at all confident, 5=extremely confident). Range of scores 5-25.
Time frame: Change from Baseline to 12 weeks
Physical Activity Enjoyment Scale (PACES)
Assesses the degree to which the individual enjoys exercise. The Physical Activity Enjoyment Scale is an 18-item scale that assesses enjoyment for physical activity by asking participants to rate "how you feel at the moment about the physical activity you have been doing" using a 7- point bipolar Likert scale, from 1 (I enjoy it) to 7 (I hate it). Eleven items were negatively worded and seven items were positively worded. After reverse scoring the 11negatively worded items, an overall enjoyment for physical activity score is determined by summing the items, with a range of 18-126 being possible. Higher scores indicate higher enjoyment.
Time frame: Change from Baseline to 12 weeks
Outcome Expectancies Questionnaire
Assesses what benefits the individual expects to gain from exercise. Responses on a scale from 1-5 (1=strongly disagree, 5=strongly agree), with participants indicating how strongly they agree to potential outcomes of exercise. Scores range from 9-45 with higher scores indicating greater outcome expectation.
Time frame: Change from Baseline to 12 weeks
Plan to share: No — IPD will not be shared with other researchers.
Ran from Jul 2018 to primary completion in Sep 2019, 14 months.
Of 1,032 non-industry interventional studies with no phase under Cardiovascular Diseases, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 48. This study's 14 months is below that.
Counting every sponsor, half of 1,148 studies reached it within 26 months; a quarter within 13 and three quarters within 49.
Cardiovascular Diseases covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.
