The study purpose was to examine the impact of providing individualized body
composition information (intervention condition; n = 40) versus body weight information
(standard control condition; n = 40) on motivational regulations in overweight female
exercise initiates about to commence an exercise program. The Behavioral Regulation in
Exercise Questionnaire-2 was completed prior to and following the information provision.
Results revealed a significant increase in introjected regulation for the intervention
condition indicating that the body composition information may have reinforced previous
feelings of self-imposed pressure and a sense of obligation to start exercising. Implications
for motivating new exercisers are discussed.
