Expert bodies and health organisations recommend that adults undertake at least 150 min.week of moderate-intensity physical activity (MPA). However, the underpinning data largely emanate from studies of populations of

Imprecise measurement of physical activity variables might attenuate estimates of the beneficial effects of activity on health-related outcomes. The researchers aimed to compare the cardiometabolic risk factor dose-response relationships for physical activity and sedentary behaviour between accelerometer- and questionnaire-based activity measures.
