Do Changes In Affective Responses During Physical Activity Predict Future Physical Activity Behavior In Older Adults?

Background: Gaining insight into factors related to moderate-to-vigorous physical activity (MVPA) behavior may assist development of behavior change interventions targeting older adults. Purpose: To explore direct and indirect associations between older adults’ affective responses during MVPA and future MVPA behavior via self-efficacy beliefs and self-determined motivation. Methods: Data were collected from 82 older adults before, during, and after a walking bout; MVPA behavior was measured 1 month later via telephone. Results: Increases in tranquility during MVPA were indirectly correlated with future MVPA behavior via self-determined motivation (p < .05), but not self-efficacy beliefs (p > .05). Decreases in positive engagement and tranquility during MVPA were directly and positively linked with future MVPA behavior, whereas increases in revitalization during MVPA and self-determined motivation were directly and positively linked with future MVPA behavior (p < .05). Conclusions: Changes in older adults’ affective responses during MVPA may be important correlates of future MVPA behavior
