TODDLERS NEED MORE EXCERCISE!


Even toddlers need to get more exercise, study says

LONDON - New research suggests even 3-year-olds aren't getting enough exercise, raising concerns over their weight, future disease risk, psychological well-being, behavior and learning ability.
In the first study to rigorously track the movements of preschoolers, scientists found that the average 3-year-old is physically active for just 20 minutes a day, well short of the recommended hour a day for that age.
In The Lancet study published this month, scientists from the University of Glasgow in Scotland recruited 78 children. Each 3-year-old wore an "accelerometer," a matchbox-sized monitor clipped to the waistband, for a week.
The device, worn from the time they woke up until bedtime, gave minute-by-minute readings of the children's pattern of physical activity and the number of calories burned.
The toddlers were burning about 1,300 calories a day - less than the 1,500 calories recommended.
While the problem is one of an imbalance of calories eaten and burned up, experts believe the main reason is children are not exercising enough.
"There are really only two possibilities, reduced activity or increased intake. None of the dietary assessment data indicate that children are eating more. Adolescents may be eating more but young children are eating less," said the study's leader, John Reilly, a physiologist at the University of Glasgow.
"A 3-year-old 25 years ago was eating 25 percent more than a 3-year-old today," he said. "But physical activity levels have dropped quite dramatically over the last 15 or 20 years."
In the study, the children were spending between nine and 10 hours of their day hardly moving at all.
"They may well have been doing a bit of fidgeting, they may have been speaking to their parents or among themselves, but they were just not moving enough to put up the number of calories burned beyond what it would be if they were just resting or sleeping," Reilly said.
The children spent 20 minutes a day in moderate to vigorous activity - the type of activity that would get them feeling slightly warm and slightly out of breath, such as running around, walking to keep up with an adult and most types of outdoor play.
All-day television and recorded videos are a major culprit, Reilly said. Outside the home, children are also much less active than they used to be.
"Many more journeys are made by car and among the 3-year-olds, a fair number of them are being taken around in strollers when they could arguably have been walking," he said.
Another element is recent concerns over safety. Some local authorities in Britain have banned children from bringing balls into playgrounds while others prohibit tree-climbing.
"There needs to be a balance. Perhaps we've taken the n
and safety agenda a bit far," Reilly said.
The dangers of a sedentary childhood go beyond obesity, experts say. More active children tend to be better behaved, and scientists suspect more active children learn more effectively, perhaps because physical activity is a stimulus to brain development.
