Brief periods of inactivity hasten the onset of diabetes


So we look at trying to
prevent or at least slow muscle loss as we age. So
we know as we get older, past the age of about 50 to 55, we begin to lose muscle mass and strength. And what we try to do is
to look at nutritional and exercise interventions
to counteract that process. So we looked at older
adults between the ages of 60 and 85 years of age,
and they were actually pre-diabetic already, so we looked at how that period of inactivity not only controlled or regulated muscle groups but also how it affected
their blood sugar control. So what we found was
that when older adults reduce their daily step
count for two weeks the people who were pre-diabetic demonstrated symptoms
of full blown diabetes and that weren’t fully recovered simply by returning to daily
steps within two weeks. The thing is that we know
these periods of inactivity are often unavoidable, so
for example in the winter it gets extremely cold
and older people might not want to venture outside,
so they kind of quarantine themselves in the house
for short periods of time. So it’s generally
unavoidable, so what we’re trying to do is to develop
nutrition and exercise strategies to try and counteract those negative effects of
those periods of inactivity. (gentle tinkling music)
