Great Expectations: A Qualitative Analysis of the Factors That Influence Affective Forecasts for Exercise.

The extent to which people expect to feel pleasure during exercise is proposed to influence an individual's decision to be active. In order to identify the factors that shape this affective forecast for exercise, this study explored what people think about when creating their affective forecast for exercise. Thirty-one inactive participants provided an affective forecast for a moderate intensity exercise session using the global affective forecast questionnaire. Immediately after, they were asked a series of questions to verbally explain what they were thinking about in order to generate their forecast. Thematic analysis identified four themes relating to the exercise intensity, the exercise outcomes, the exercise environment, and the enjoyment of exercise that influenced affective forecast creation. Exercise practitioners should design strategies to manipulate these factors, and structure exercise environments to support a positive affective forecast and better motivate exercise participation.
