简要总结
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.

结局指标
主要结局
Anticipated During Exercise Affect (Session 2)
时间窗: prior to exercise session
How one anticipates that they will feel during exercise session 2 (an exercise session that is identical to exercise session 1).This was assessed prior to exercise session 2 via a 100 mm visual analogue scale (range 1-100) where a higher number indicates more positive affect.
Mean During Exercise Affect (Session 1)
时间窗: average score assessed every 5 minutes during exercise, up to 30 minutes
Average during exercise Feeling Scale (FS) score which was assessed every 5 minutes during exercise. Feeling Scale scores range from -5 to +5 with higher values indicating more positive affect.
Post-exercise Affect (Session 1)
时间窗: 15 minutes post-exercise
Feeling Scale (FS) score 15 minutes post-exercise. Feeling Scale scores range from -5 to +5 with higher values indicating more positive affect.
Memory of Post-exercise Affect (Session 1) - Calculated as the Difference Between Recalled Post-exercise Affect and Actual Post-exercise Affect
时间窗: 15 minutes and 7 days post-exercise
Calculated as follows: recalled post-exercise affect (assessed 7 days following exercise session) minus actual post-exercise affect (Feeling Scale score assessed 15 minutes post-exercise). Possible scores for both recalled affect and actual affect range from -5 to +5, where higher numbers indicate more positive affect. A negative change value indicates that participants remembered feeling less positive post-exercise than they actually felt.
Pre-exercise Affect (Session 1)
时间窗: Prior to exercise
Measured using Feeling Scale (FS) prior to exercise bout. Scores range from -5 to +5 with higher values indicating more positive affect
Memory of During Exercise Affect (Session 1) - Calculated as the Difference Between Recalled During Exercise Affect and Actual During Exercise Affect
时间窗: average score assessed every 5 minutes during exercise, up to 30 minutes, and 7 days post-exercise
Calculated as follows: recalled during exercise affect (assessed 7 days post-exercise) minus actual during exercise affect (average of Feeling Scale scores every 5 minutes during exercise). Possible scores for both recalled affect and actual affect range from -5 to +5, where higher numbers indicate more positive affect. A negative change value indicates that participants remembered feeling less positive during exercise than they actually felt.
次要结局
- Pre-exercise Affect (Session 3)(Prior to exercise)
- Mean During Exercise Affect (Session 3)(average score assessed every 5 minutes during exercise, up to 30 minutes)
- Post-exercise Affect (Session 3)(15 minutes post-exercise)
