This randomized controlled trial assigned insufficiently active, overweight or obese adults to morning exercise, evening exercise, or a waitlist control for 12 weeks and assessed how participants restructured daily time use. Both exercise groups predominantly reduced TV time to accommodate new exercise, with similar patterns of time reallocation whether exercise was performed in the morning or evening.
Participants in the exercise groups completed a 12-week program prescribing ≥250 min/week of moderate-vigorous physical activity, performed either between 0600–0900 or 1600–1900. Eighty-two participants completed the intervention. Patterns of time reallocation were similar between morning and evening exercise groups. Limitations include the inability to blind participants, reliance on self-reported time use data with potential recall bias, and no follow-up data after the intervention ceased.
