Physical inactivity can lead to
serious illnesses!
January 23, 2005
University of Missouri-Columbia researchers in a study
published in the Journal of the Physiological Society
have revealed that in as little as two days of physical
inactivity, a body's efficient use of insulin may decrease.
In a study involving rats, Frank Booth, professor of
biomedical science and director of the MU Health Activity
Center, and David Kump, a doctoral student in the Department
of Medical Pharmacology and Physiology, found that insulin
sensitivity decreases the longer the rats stay inactive.
This decreased insulin efficiency may be a precursor
to diabetes and other related diseases.
"The less efficient your insulin is, the greater
risk you have of diabetes, heart disease, obesity and
hyptertension. Insulin works by taking glucose, or blood
sugar, out of the blood stream and into the muscle to
be used for energy. Our research found that when the
rats stopped running for two days, the amount of sugar
taken into the muscle in response to insulin was reduced
by about one-third," said Kump.
"Everyone is looking at the benefits of exercise,
but we are looking at the consequences of stopping that
exercise. People already know that exercise is good
for them. This shows that within a very short time frame
of inactivity, the insulin does not work as well and
might have negative effects," he added.
