Accurate and precise tools and data processing techniques for assessing physical activity and sedentary behaviors are critical in order to identify strong predictors of behavior, dose-response relationships, and to accurately assess the effects of behavioral interventions. This need is especially urgent for younger children who lack the cognitive ability to accurately recall the duration and intensity of their physical activity and the pattern of their sedentary behaviors.
Current research focuses on calibrating accelerometers in free-play settings across the pediatric age range, testing consumer activity tracking devices, and identifying peer influences on adolescent physical activity, screen time, and dietary behaviors.
The Physical Activity and Health Lab uses a variety of research-grade accelerometers and pedometers; consumer activity tracking devices; portable indirect calorimetry system for measuring energy expenditure, and a direct observation system using coded videos of unscripted behaviors.
