Comparison of Affect-based, Self-selected, and Traditional Exercise Prescriptions

Szczegółowy opis
The purpose of this study is to determine if an "affect-based" or "choice-based" exercise prescription is more effective for behavior change than a traditional, "moderate-intensity" exercise prescription. Prior research suggests that "choice-based" or "self-selected" exercise intensity is more pleasant and adhered to than "moderate-intensity exercise" (Williams et al., 2014). Similarly, affect-based exercise prescriptions (i.e., an exercise prescription where intensity is regulated based on the pleasure-displeasure one feels while exercising) appear to have merit (Baldwin, Kangas, Denman, Smits, Yamada, & Otto, 2016).
However, choice-based and affect-based exercise prescriptions have not been compared to each other. Further, it is unknown if it is the intensity regulation that matters (e.g., "choose an intensity that feels good" or the focus on affect (e.g., "focus on feeling good). Third, prior research has not objectively measured physical activity behavior.

Broń i interwencje
Grupa uczestników / Arm |
Interwencja / Leczenie |
|---|---|
|
Eksperymentalny: Choice-No Affect
These participants self-select (i.e., choose) their exercise intensity with the goal of walking 30-60 minutes on most days of the week.
For safety reasons, they are instructed not to exceed 59% of their heart rate reserve.
This is choice-based exercise intensity with no focus on positive affect.
|
Participants are instructed to choose whichever intensity they want, rather than regulate their intensity based on heart rate.

Eksperymentalny: Choice-Affect
These participants self-select their exercise intensity with the goal of walking 30-60 minutes on most days of the week.
They're instructed to choose the intensity that makes them feel the best.
For safety reasons, they are instructed not to exceed 59% of their heart rate reserve.
This is choice-based exercise intensity with a focus on positive affect.

|
|
Eksperymentalny: No Choice-Affect
These participants regulate their exercise intensity using their heart rate, with the goal of walking 30-60 minutes on most days of the week.
The intensity is "moderate" according to the American College of Sports Medicine (40-59% of their heart rate reserve).
Meanwhile, these participants are instructed to focus on the "good feelings" that come with exercise.
this is heart rate-based exercise intensity with a focus on positive affect.
