Feelings About Exercise

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.
