Objective: The purpose of this study was to see if portable play equipment added to a preschool playground resulted in higher intensities of physical activity among 3-5-year-old children.
Methods: Activity-friendly equipment was added to an outdoor preschool playground. Accelerometry-measured intensities of 15-s epochs of physical activity were tracked for 5 pre-intervention and 5 post-intervention days during outdoor play. Data were collected during fall 2005 in Salt Lake City for 64 preschoolers aged 3, 4, and 5 years.
Results: After the intervention, both male and female 3- to 5-year-olds significantly decreased sedentary behavior and significantly increased light, moderate, and vigorous physical activity as measured by accelerometry.
Conclusions: Results suggest simple interventions, requiring little teacher training, can yield increases in healthy physical activity.
