简要总结
The primary purpose of the proposed study is to examine the effect of a home-based physical activity variety intervention on objectively measured physical activity in an eight-week randomized intervention trial.
详细描述
The primary purpose of the proposed study is to examine the effect of a home-based physical activity variety intervention on objectively measured physical activity in an eight-week randomized intervention trial. Early research on physical activity variety has observed increased physical activity participation, motivation, and enjoyment as a result of physical activity variety. However, previous studies examining variety have not included home-based interventions, objective measures of physical activity, or cardiovascular fitness classes.
Forty low-active college students will be randomly assigned to either an eight-week physical activity variety intervention (n=20) or a physical activity consistency comparison condition (n=20). Physical activity will be assessed via an accelerometer (e.g., Actigraph) at baseline and eight weeks, and psychosocial variables at baseline, four weeks, and eight weeks (i.e., post-intervention). Affect will be assessed at one, four, and eight weeks. Participants will receive counseling sessions and access to a website containing workouts appropriate to their condition.

研究组 & 干预措施
Physical activity variety intervention
Participants in the variety condition will be sent the link to their condition's website via email. The variety website will contain nine distinct high intensity interval training (HIIT) videos. The videos will be 30-minutes containing a five-minute warm-up, 20-minute workout, and a five-minute cool down. The website will emphasize the importance of having variety in one's physical activity routine. This will include reminders to have variety in selected workouts and the benefits associated with doing so. This emphasis will be supported through the counseling sessions provided to participants in the variety condition.
干预措施: Physical activity variety intervention (Behavioral)
Physical activity consistency comparison condition
Upon the completion of randomization, participants in the consistency condition will be sent the link to their condition's website via email. The consistency website will contain one HIIT video. The video will be 30-minutes and include a five-minute warm-up, 20-minute workout, and a five-minute cool down. The website will emphasize the importance of having consistency in one's physical activity routine. This will include reminders to be consistent in workouts and the benefits associated with doing so (Guiney & Machado, 2013). This emphasis will be supported through the counseling sessions provided to participants in the consistency condition.
干预措施: Physical activity consistency comparison condition (Behavioral)
结局指标
主要结局
Actigraph
时间窗: Measuring the change from baseline to week 8.
An electronic device worn on the right hip to identify motion.
7-Day Physical Activity Recall Interview
时间窗: Measuring change weekly from baseline until the eighth week of the intervention.
Allows for tracking all bouts of MVPA that are at least 10 minutes in duration over the previous week. Physical activity is reported as minutes spent in moderate, hard, and very hard activities.

- Behavioral Regulation in Exercise Questionnaire (BREQ-2)(At baseline, weeks 4, and 8.)
- Bored of Sports Scale (BOSS)(At baseline, weeks 4, and 8.)
- Physical Activity Enjoyment Scale (PACES)(At baseline, weeks 4, and 8.)
- Motives for Physical Activity Measure-Revised (MPAM-R)(At baseline, weeks 4, and 8.)
- Psychological Need Satisfaction in Exercise (PNSE)(At baseline, weeks 4, and 8.)
- Feeling Scale (FS)(At weeks 1, 4, and 8.)
- Exercise-Induced Feeling Inventory (EFI)(At baseline, weeks 4, and 8.)
