Identification as an exerciser may promote physical activity. This study examined exercise identity (EI) and its relationship with demographic characteristics and exercise among adults participating in behavioral weight loss treatment, which is a key target population for increasing exercise.
Longitudinal.
Participants (N = 320) completed a measure of EI and exercise was assessed with accelerometers at baseline and 6 months.
Baseline EI and exercise were positively related and EI and exercise increased over time. However, change in EI was not meaningfully related to change in exercise, baseline EI did not predict change in exercise, and 6-month EI was not related to 6-month exercise. Participants identifying as non-White reported greater EI but lower exercise.
Although EI and exercise may increase among weight loss participants, the two may not be meaningfully related during active weight loss treatment. The relationship between EI and exercise may also differ based on race.
•Exercise identity related to exercise at baseline among weight loss participants.•Exercise identity was stronger among participants identifying as non-White.•Both exercise identity and exercise increased during 6 months of treatment.•Surprisingly, change in exercise identity did not relate to change in exercise.•Exercise identity and behavior also were not meaningfully related at month 6.
