Youth Fitness: Do young Americans get enough exercise?

American youth are in worse physical shape than earlier generations, many fitness experts claim. According to the U.S. surgeon general, only about one-half of U.S. children get regular exercise, and one-fourth don't take part in physical activity at all. As a result, obesity among children and adolescents has increased substantially since the 1960s. The conveniences of modern life - notably television, video games and computers - get much of the blame for creating a nation of youthful couch potatoes. In addition, school officials often scale back or eliminate physical education programs when budget squeezes occur. Nonetheless, innovative physical educators are working to reverse the trend by acquainting kids with activities that interest them - and that can help them maintain fitness throughout life.
