João Magalhães' current research interests focus on the graded and dose-response relationships between sedentary behavior and physical activity, with obesity, metabolic and other chronic diseases across the life span, and related mechanistic and prevention models, with a special focus on exercise interventions on people with type-2 diabetes.
Further interests are on the assessment of Energy Expenditure and Physical Activity Using reference methods (doubly labeled water) and objective methods (proportional actigraphy, and combined sensors using heart rate and motion sensors).
