Camden Active Spaces project was a ground-breaking Public Health initiative to deliver challenging and intriguing active spaces to several Camden schools with the specific goal of increasing pupils’ physical activity levels. A further aim of the preventative healthcare project was to also open the school playgrounds for the community outside school hours. University College London’s Sports Scientists monitored change in pupil activity levels before and after the installation of the new active spaces to provide important data for understanding the drivers for physical activity. It found that the measures considerably reduced sedentary times and (established through interviews) increased wellbeing through social interaction. The outcome was published in various medical journals.
