About us

Sedentary behaviour – too much sitting as distinct from too little physical activity – is now recognised as an independent risk factor for cardiometabolic disease risk and premature mortality. This is problematic as technological advancements in transportation, communications, workplaces, and domestic entertainment has created environments that encourage engagement in sedentary behaviour.

The Physiology of Sedentary Behaviour Special Interest Group investigates the relationship between sedentary behaviour patterns and cardiometabolic disease risk and the benefits of interrupting prolonged sedentary time in various population groups including office workers, school children, spinal cord injury, and Type 2 diabetes. The aim of this research is to influence public health policy and clinical care guidelines with an emphasis on reducing prolonged sedentary behaviour.
