Sydney:
Physically active children are more likely to keep diabetes and
heart disease at bay, a new study reveals.
The study, led by researchers Glenn McConell and Mary Wlodek from
Victoria and Melbourne Universities, tested whether exercise could
re-programme rats predisposed to diabetes and heart disease owing
to their lower birth weight.
"Those born small are programmed for a higher chance of disease
later in life because of their underdeveloped heart and pancreas,
but we think you can re-programme yourself by exercising early in
life," said McConell, the American Journal of
Physiology-Endocrinology and Metabolism reported.
In the trials on rats born small, those that exercised from five
to nine weeks of age showed a small improvement in organ function
at the end of that month, but remarkably, six months later their
organs were the same as the healthy control group, a university
statement said.
Another group of born small rats were not exercised and showed no
improvement. McConell said a nine-week old rat correlated roughly
with a five-year-old child and a six-month-old rat with a young
adult person.
"We think this means more activity for children and more physical
education in school could really help set them up for better
health later in life and even help those predisposed to diabetes
and heart disease to re-program themselves in time to avoid it,"
added McConell.
