Brief Summary

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.

Detailed Description

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.

Study Groups

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.

Group Type: EXPERIMENTAL

Physical activity variety intervention

Intervention Type: BEHAVIORAL

The counseling in the variety condition will serve many purposes. The first session will concentrate on informing participants on the importance of having variety in their physical activity routine and how to access the variety of physical activities available to them. The variety condition will be instructed to complete at least three different HIIT workouts per week. They will be encouraged to complete more than three workouts. The following counseling sessions will be provided to not only continue supporting variety in physical activity but also to support participants' basic psychological needs.

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.

Group Type: ACTIVE_COMPARATOR

Physical activity consistency comparison condition

Intervention Type: BEHAVIORAL

The counseling in the consistency condition will serve many purposes. The first session will concentrate on informing participants the importance of having consistency in their physical activity routine and how to access the HIIT workout available to them. The consistency condition will be instructed to complete the provided HIIT workout three times per week. They will be encouraged to complete more than three workouts. The following counseling sessions will be provided to not only continue supporting consistency in physical activity but also to support participants' basic psychological needs.
