Prospective effects of pedometer use and class competitions on physical activity in youth: A cluster-randomized controlled trial

Effects of a School‐Based Pedometer Intervention in Adolescents: 1‐Year Follow‐Up of a Cluster‐Randomized Controlled Trial

“…These findings expand our knowledge on the efficacy of “läuft.,” because short‐term effects of the intervention on students' out‐of‐school sports activities, weekly MVPA, as well as active commuting, but neither on cardiorespiratory fitness nor on BMI, have been shown already . Therefore, we were able to show that the effects of a pedometer intervention on indicators of everyday PA as well as body composition could be sustained for a period of 1 year after the end of the intervention, ie, “läuft.” might have the potential to contribute to establishing a more active lifestyle and to counteract the decrease of PA during adolescence.…”

“…A cluster‐randomized controlled trial with 3 waves of assessment was conducted. Details about randomization, sample size calculation, and short‐term effects have been published previously . Briefly, all secondary schools in 6 districts of the federal state of Schleswig‐Holstein in Germany (N = 134) were invited to participate with their eighth grade classes.…”

“…Details about randomization, sample size calculation, and short-term effects have been published previously. 24,25 Briefly, all secondary schools in 6 districts of the federal state of Schleswig-Holstein in Germany (N = 134) were invited to participate with their eighth grade classes. Of these, 29 schools with 61 classes and 1489 students decided to take part in the study.…”

“…A cluster‐randomized controlled trial with 3 waves of assessment was conducted: before, immediately after, as well as 1 year after the end of intervention. First evidence for the effectiveness of the “läuft.” program on increased PA was found for postassessment . The current study examines follow‐up data 1 year after the intervention has ended in order to close the gap of vigorous evaluation studies including a follow‐up and to investigate whether the intervention had a lasting effect on adolescents' PA. Further outcomes, which will be examined, are cardiorespiratory fitness and weight status.…”
