This first Surgeon General’s report on physical activity is being released on the eve of the Centennial Olympic Games-the premiere event showcasing the world’s greatest athletes. It is fitting that the games are being held in Atlanta, Georgia, home of the Centers for Disease Control and Prevention (CDC), the lead federal agency in preparing this report. The games’ 100-year celebration also coincides with the CDC’s landmark 50th year and with the 40th anniversary of the President’s Council on Physical Fitness and Sports (PCPFS), the CDC’s partner in developing thisreport. Because physical activity is a widely achievable means to a healthier life, this report directly supports the CDC’s mission-to promote health and quality of life by preventing and controlling disease, injury, and disability. Also clear is the link to the PCPFS; originally established as part of a national campaign to help shape upAmerica’s younger generation, the Council continues today to promote physical activity, fitness, and sports for Americans of all ages.
