Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study seeks to investigate why some individuals exercise more than others by focusing on feelings related to exercise. This two part study first examines whether regular exercisers (n=30) and non-exercisers (n=30) differ in how a 30-minute moderate-intensity exercise bout makes them feel. All participants will walk on a treadmill for 30 minutes on two separate occasions and will be asked to report on how they feel before, during, and after exercise, how they anticipate that exercise will make them feel, and how they remembered feeling during exercise. In addition, after exercise session #2, non-exercisers will be randomized to: 1) a brief intervention focused on providing general information about the physical activity guidelines, or 2) a brief intervention which provides general information about physical activity guidelines, but also focuses on affective responses to physical activity. Non-exercisers will complete an identical, third exercise session approximately 1-week following this intervention. Further, all participants will receive a 12-week, Internet-delivered weight loss program following all exercise visits and physical activity will be assessed before and after the weight loss program.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Physical activity information - for non-exercisers only

Non-exercisers randomized to this condition will receive basic information about physical activity. This includes the national physical activity guidelines,clarification of 'moderate-intensity', exercise safety, and the progression of physical activity within the weight loss program.

Group Type ACTIVE_COMPARATOR

Physical activity information

Intervention Type BEHAVIORAL

Participants will receive general information about exercise safety, physical activity guidelines, and exercise intensity.

Affect and physical activity - for non-exercisers only

Non-exercisers randomized to this condition will receive the same basic information about physical activity as described above, but they will also receive a brief intervention focused on affective responses to exercise.

Group Type EXPERIMENTAL

Affect and physical activity

Intervention Type BEHAVIORAL

The focus of this intervention is to help the participant to become more aware of their positive feelings and experiences related to exercise. They will learn about typical affective responses to exercise, view their own affective responses to exercise, and they will be taught cognitive strategies for altering affective responses to exercise. Participants will also receive general information about exercise safety, physical activity guidelines, and exercise intensity.

Exercisers

Engaging in \>=150 min/week of moderate-intensity exercise over the past 6 months and a most recent typical week

Group Type NO_INTERVENTION

No interventions assigned to this group

Non-exercisers

Engaging in \<30 min/week of moderate-intensity exercise over the past 6 months and a most recent typical week

Group Type NO_INTERVENTION

No interventions assigned to this group
