Feasibility of the Promoting Pupils' Physical Literacy (3PL) intervention: Does it work? Will it work?

backgroundThe rise in physical inactivity among children poses serious health risks impacting physical, mental, and social well-being. Physical literacy (PL) has been identified as an effective approach to encourage long-term physical engagement. Schools and communities, particularly through physical education (PE) programs, play a critical role in promoting PL. However, while there are several PL-focused PE interventions worldwide, no such programs have been specifically tailored to Nordic contexts, making feasibility testing essential for effective implementation. This study investigated the feasibility of a Danish adaptation of an Irish PL program, Y-PATH.

methodsThe adapted program, the Promoting Pupils' Physical Literacy (3PL) intervention, provided PE teachers with resources, courses, and a website to enhance motivational climates in PE and promote PL among 4th and 5th grade pupils. The study was conducted in accordance with Medical Research Council guidelines and Bowen et al.'s (2009) framework. Feasibility indicators including acceptability, demand, implementation, practicality, adaptation, and integration were investigated using a weekly questionnaire for PE teachers, interviews (n = four teachers and 20 pupils), observations, and field notes. The quantitative data were analyzed descriptively, while the qualitative data were analyzed using thematic analyses.

results3PL was found to be feasible and acceptable among pupils and teachers (e.g., materials were used in 71% of lessons). While the materials supported implementation for teachers, workload adjustments are needed. Teachers adapted lessons effectively, balancing an inclusive and motivating learning environment. Despite minor challenges, 3PL fostered engagement among pupils and teachers with potential for expansion.

conclusion3PL represents a feasible and promising approach to promote PL in a Danish school setting. Feasibility testing demonstrated the potential for scaling 3PL, while recognizing that large-scale trials are needed to validate its broader impact.

trial registrationA protocol for adaptation of 3PL was published in Open Science Framework, registered in December 2022 (1). The 3PL study was preregistered at ClinicalTrials.gov (ID NCT05822024), April 2023, version 1 ( https://classic. CLINICALTRIALS: gov/ct2/show/NCT05822024 ), before enrolment. A study protocol was written before intervention start (August 2023) and hereafter officially published in January 2024 (2).
