would like to sweat it out in the
gym, just a few minutes of
sedentary time with some sort
of movement may help improve
your health. In a new study involving over 3,000 people
aged 50 to 79, the researchers
found that the least active people were five times more likely to die during the study
period than the most active
people and three times more
likely than those in the middle
range for activity. "Activity doesn't have to be
especially vigorous to be
beneficial. That's the public
health message," said study
lead author Ezra Fishman from
University of Pennsylvania in the US. These findings were
published in the journal
Medicine & Science in Sports &
Exercise. For the study, the participants
wore ultra-sensitive activity
trackers, called accelerometers,
for seven days, generating data
compiled by the US Centers for
Disease Control and Prevention (CDC). For these same people,
the agency then tracked
mortality for the next eight
years. "When we compare
people who exercise the same amount, those who sit less and
move around more tend to live
longer," Fishman said. "Those who were walking around, washing the dishes, sweeping the floor tended to live
longer than the people who were
sitting at a desk" Fishman
noted. Though the scientists did
not discover any magic
threshold for the amount a person needs to move to
improve mortality, they did learn
that even adding just 10
minutes per day of light activity
could make a difference. So, what's your take-home
message? Replace 30 minutes
of sedentary time with light or
moderate-to-vigorous physical activity produced even better results. "When it comes to
physical activity," Fishman said,
"more is better than less, and
anything is better than nothing."
