Latest studies in area of physical activity by American children showed astounding negative results in last decade. Journal of Pediatrics concludes that American children need to get up and away from the TV and computer and out exercising at least an hour a day. There are very clear evidences that the physical activity by American children and adolescents has decreased dramatically in the last 10 to 20 years, what is very anxious. This affirmed panel co-chair Dr. Robert M. Malina, research professor and an expert in growth and development at Tarleton State University in Stephenville, Texas.

Obviously the technological revolution from the end of last century produced new ways for kids to stay sedentary instead of being more active as in past.

There is wide range of health factors impacted in children and teenagers last 20 years, what states thousands of articles containing this data.
"Increasing the level of habitual moderate to vigorous intensity physical activity in youth is a health promotion and a disease prevention strategy," the panel concluded.

Generally, a minimum of an hour a day of physical activity is reasonable and can be achieved by most children with some effort. Today's children are more sedentary but are still consuming about the same amount of calories as more active children of a decade or two ago. That means that children are just not burning up enough calories they produce today.
The parents and all of us need to help children increase the amount of time spent in moderate to vigorous physical activity. Also the teachers in schools needs to bring more time spending with children performing any kind of physical activities.

The major role in this could play the physical education classes and other school- and community-based recreation programs.
