The Physical Activity Messaging Framework (PAMF) and Checklist (PAMC): International consensus statement and user guide.

Effective physical activity messaging plays an important role in the pathway towards changing physical activity behaviour at a population level. The Physical Activity Messaging Framework (PAMF) and Checklist (PAMC) are outputs from a recent modified Delphi study. This sought consensus from an international expert panel on how to aid the creation and evaluation of physical activity messages. In this paper, we (1) present an overview of the various concepts within the PAMF and PAMC, (2) discuss in detail how the PAMF and PAMC can be used to create physical activity messages, plan evaluation of messages, and aid understanding and categorisation of existing messages, and (3) highlight areas for future development and research. If adopted, we propose that the PAMF and PAMC could improve physical activity messaging practice by encouraging evidence-based and target population-focused messages with clearly stated aims and consideration of potential working pathways. They could also enhance the physical activity messaging research base by harmonising key messaging terminologies, improving quality of reporting, and aiding collation and synthesis of the evidence.

The effect of a classroom activity break on physical activity levels and adiposity in primary school children.

AIM: Despite recognition that regular physical activity is essential for good health, many children do not accumulate sufficient daily physical activity. The aim of this study was to examine the effect of a classroom-based activity break on accelerometer-determined moderate-to-vigorous intensity physical activity (MVPA) and adiposity in primary school children. METHODS: One hundred twenty children from seven primary schools in Northern Ireland participated in the study. In each school, one class of children was randomly assigned to an intervention group and another class to a control group. Teachers of the intervention classes led a 5-min activity break three times per day for 12 weeks. Accelerometer-determined MVPA, height, weight and four skinfolds were measured at baseline and post-intervention. RESULTS: Compared with the control group, the intervention group significantly increased weekday MVPA (+9.5 min) from baseline to post-intervention. There were no significant changes in BMI; however, an increase in sum-of-skinfolds of the intervention group was observed. CONCLUSIONS: Classroom-based activity breaks led by the teacher are successful in increasing children's physical activity levels. The programme shows a positive step in improving overall physical activity levels and contributing to the goal of 60 min daily MVPA.
