When examining the physical activity levels of children, the data in this study show that extracurricular school sports should not be considered equal. The observational method of assessing physical activity and the small amount of schools represented in this sample are among the limitations of this study.
About the Study:
Using the System for Observation Play and Leisure Among Youth in 6,735 middle school children in four schools in Wake County, North Carolina, the amount of students in sedentary, moderate, and vigorous activity was objectively measured. Energy expenditure and intensity of physical activity (MET values) were also estimated.
