According to the United States the most comprehensive children's physical activity to a survey, 9-year-old to 15-year-old child's daily physical activity significantly decreased, in fact, less than one-third of the 15-year-old child, every day for 60 minutes to reach the minimum standards of appropriate or violent Campaign.

The study is based mainly on the U.S. obesity epidemic on children. U.S. 23,000,000, or about one-third of children overweight, which increases their suffering from type 2 diabetes, high cholesterol and other health risks.

By measuring the activities include cycling, rope skipping, dancing, walking and running quickly, and so on. The study showed: 9-year-old sports daily average 3 hours; 15-year-old children an average of 49 minutes exercise, exercise 35 minutes on average over the weekend; 15-year-olds, only 31% of the daily exercise of at least 1 hour, only 17% of the campaign over the weekend At least 1 hour.

On the whole, more boys than girls to actively campaign, an average of more than 18 minutes, 13 minutes more on weekends.
