Affective responses during physical activity predicting same day and next day physical activity in emerging adulthood: an Ecological Momentary Assessment study.

The purpose of the current study was to examine how affective responses during physical activity (PA) captured in real-time and real-world settings During a 10-day study, physically active participants wore an accelerometer which captured PA and triggered EMA prompts during PA to capture affect (e.g. positive, negative). Additional EMA prompts captured affect during non-PA. Emerging adults ( There is inconsistent evidence that affective responses during PA can predict same day and next day PA. Future work should examine the affect-physical activity link among those who are insufficiently active and across person-specific micro-timescales.
