Population Group
National Statistics (Health People 2010)
Adults 40% do not participate in any leisure activity
Adults 61% are obese or overweight
High School Students
35% do not participate in vigorous physical activity
Children (2-18 years old)
Average 4 hours/day being sedentary (TV, computers)
US households Take 12 auto trips/day; 1/4 are less than a mile

“Physical inactivity contributes substantially to the global burden of disease, death and
disability.”
WHO: ~ 2 million deaths per year

Summary Summary
Physical activity: Many benefits… Decreases cardiovascular risk factors Independent of weight loss Physical activity is an independent predictor
of mortality… Leanness ≠ invincible
