Sport has a potentially important role in contributing to total energy expenditure [total physical activity] and to promoting health and preventing non-communicable disease. Given decreases in work and transport physical activity, sport has an increasingly important role in maintaining and increasing activity levels in the whole population. Sport agencies and organizations, including the International Olympic Committee (IOC) and the The Association For International Sport for All (TAFISA) are working to broaden the sport agenda, beyond elite and competition sports, to include community-wide participation at the grassroots level. Combining the efforts of Sport and other sectors, especially Health and Education, can contribute to greater investments in sport, as a component of promoting health-enhancing levels of physical activity. Working together in partnerships could build on the community interest generated by Olympic Games and other mass events, to contribute to increased physical activity among all age groups, and resultant better health for all.
