The aim of this study was to determine the impact of pedometer use and self-regulation strategies on adolescents’ daily physical activity.
Junior high school students (n = 113) enrolled in seventh- and eighth-grade physical education classes (52 girls, 61 boys) volunteered to participate in a 5-week study to assess daily step counts. Ten physical education classes were randomly assigned to 1 of 3 groups: (a) self-regulation, (b) open, and (c) control.
A repeated-measures, mixed-model analysis of variance revealed a significant 3 × 4 (Group by Time) interaction effect, F6,290 = 2.64, P < .02. Follow-up analyses indicated participants in the self-regulation group took 2071 to 4141 more steps/d than the control. No other significant differences emerged among groups on step counts.
It appears that having access to and charting daily step counts (ie, self-regulatory strategies) positively influenced young adolescents to attain a higher number of steps/d.
