The protective effect of physical activity on total mortality, life expectancy, cardiovascular disease and diabetes has been widely reported in people of all ages (Strong et al. 2005; Jonker et al. 2006; Franco et al. 2005). Recent estimates suggest that obesity and physical inactivity are responsible for 400,000 deaths annually in the United States; thus, it is close to overtaking tobacco as the leading cause of preventable death (Mokdad et al. 2004).

Cardiorespiratory fitness is a direct marker of physiological status and recent data suggest that fitness is one of the strongest predictors of health outcomes (Myers et al. 2002; Mora et al. 2003). In fact, cardiorespiratory fitness is a direct measure of physiological performance and of the ability to adapt to physical stress. Physical activity and cardiorespiratory fitness are closely related in that fitness is partially determined by physical activity patterns over recent weeks or months. Cardiorespiratory fitness is also determined b ...
