Children who sit too much may face
adult-sized health consequences, according to a sobering new study of healthy
young girls. The study found that after a single session of prolonged
inactivity, the children developed changes in their blood flow and arteries
that, in grown-ups, would signal the start of serious cardiovascular problems.
There
is plenty of evidence, of course, that uninterrupted sitting dents the health
of adults. For the new study , Ali McManus, an asso ciate professor of
pediatric exercise physiology at the University of British Columbia in Kelowna,
and her colleagues decided to ask children to sit still.
In
general, today's children are doing plenty of that. One recent large-scale
epidemiological study reported that children across the globe sit for about 8.5
hours every day . Another recent study found that activity levels among
children drop precipitously after about age 8 and continue to fall through
adolescence, with young people trading movement for sitting.
