Published in 2002, SOPLAY was designed to obtain observational data on the number of students and their physical activity levels during play and leisure opportunities in a specific activity area. SOPLAY is based on momentary time sampling techniques in which systematic and periodic scans of individuals and contextual factors within pre-determined target areas are made. During a scan the activity of each individual is mechanically or electronically coded as Sedentary (lying down, sitting, or standing), Walking, or Very Active.
