Introduction: A New Perspective on the Epidemiology of Physical Activity

There is now little dispute that regular physical activity has a beneficial effect in reducing the risk of many chronic conditions [1, 2], but it remains difficult to change population behaviour by encouraging the necessary weekly volume of physical activity [3]. One important roadblock in this task has been uncertainty about the message, and much of the general public has become cynical about public health recommendations due to frequent changes in statements about the minimum amount of physical activity needed for benefit [4].

Issues to Be Discussed In this text, we will begin by reviewing the various approaches to the measurement of habitual physical activity adopted by epidemiologists over the past
