“…Similarly, associations with several environmental and school-level factors, including weather, fixed equipment, total outdoor space, and number of outdoor physical activity areas (i.e., sports fields, ball areas, green spaces), have been largely inconclusive (15,19,(21)(22)(23). Intervention studies have supported the importance of environmental factors for increased MVPA, such as increasing playground markings and adding physical structures (e.g., soccer goals and basketball hoops), with the least active children showing the greatest improvement (20,28,29). However, several potential changes to the built environment, such as increasing the number of playground areas or providing sedentary features (i.e., benches), have been understudied and may serve to increase time spent sedentary rather than active.…”
