DALLAS (November 19, 2013) Today's kids can't keep up with their parents, according to analysis of studies on 250 million children around the world that found they don't run as fast or as far as their parents did when they were young.
Researchers say that on average, children 9 to 17 take 90 seconds longer to run a mile than their counterparts did 30 years ago.
Heart-related fitness has declined 5 percent per decade since 1975.
The American Heart Association released the research at its annual conference Tuesday in Dallas.
The group says the study is the first to show that children's cardiovascular fitness has declined worldwide over the last three decades.
