ABSTRACT

Physical inactivity is a prominent risk factor for type 2 diabetes (1) and cardiovascular diseases (CVD) (2), and along with poor nutrition, is a leading cause of mortality in North America (3). Numerous health organizations promote the use of physical activity as a therapeutic strategy for the management of metabolic risk (4-6). Unfortunately, although physicians often counsel their at-risk patients regarding physical activity (7), these patients seldom adopt the recommended behavior (8). In fact, current estimates suggest that over half of Americans (51.9%) (9) and a similar proportion of Canadians (51.0%) (10) perform less than the recommended minimum of 30 minutes of moderate-intensity physical activity on most days of the week (11).
