@article { , title = {Action 3:30R: Results of a cluster randomised feasibility study of a revised teaching assistant-led extracurricular physical activity intervention for 8 to 10 year olds}, abstract = {Many children are not sufficiently physically active. We conducted a cluster-randomised feasibility trial of a revised after-school physical activity (PA) programme delivered by trained teaching assistants (TAs) to assess the potential evidence of promise for increasing moderate-to-vigorous physical activity (MVPA). Participants (n = 335) aged 8–10 years were recruited from 12 primary schools in South West England. Six schools were randomised to receive the intervention and six acted as non-intervention controls. In intervention schools, TAs were trained to deliver an after-school programme for 15 weeks. The difference in mean accelerometer-assessed MVPA between intervention and control schools was assessed at follow-up (T1). The cost of programme delivery was estimated. Two schools did not deliver the intervention, meaning four intervention and six control schools were analysed at T1. There was no evidence for a difference in MVPA at T1 between intervention and control groups. Programme delivery cost was estimated at £2.06 per pupil per session. Existing provision in the 12 schools cost £5.91 per pupil per session. Action 3:30 was feasible to deliver and considerably cheaper than existing after-school provision. No difference in weekday MVPA was observed at T1 between the two groups, thus progression to a full trial is not warranted.}, doi = {10.3390/ijerph16010131}, eissn = {1660-4601}, issn = {1661-7827}, issue = {1}, journal = {International Journal of Environmental Research and Public Health}, note = {Comments and Suggestions : Published online 6th Jane 2019}, pages = {131}, publicationstatus = {Published}, publisher = {MDPI}, url = {https://uwe-repository.worktribe.com/output/854336}, volume = {16}, keyword = {Centre for Public Health and Wellbeing, Formerly Health & Social Sciences, physical activity, children, teaching assistants, intervention, feasibility, after-school}, year = {2019}, author = {Jago, Russell and Tibbitts, Byron and Sanderson, Emily and Bird, Emma L. and Porter, Alice and Metcalfe, Chris and Powell, Jane E. and Gillett, Darren and Sebire, Simon J.} }
