Walking Throughout Day Trumps Gym Session: StudyFriday, 15 Feb 2013
While your indoor cycling class may work up a hearty sweat, a
new study suggests that simply taking the stairs and walking
throughout your day may be better for your health.
The findings show that if you burn the same amount of calories,
standing and walking over the course of a day is better than an
hour of intense exercise when it comes to improving cholesterol
and preventing diabetes.
"Get out of your chair as much as you can, take the stairs
instead of the elevator, go by bike," and leave your car at
home, said Hans Savelberg, study author and associate professor
at Maastricht University Medical Centre in the Netherlands.
The research team followed 18 healthy adults ages 19 to 24, who performed three separate exercise regimens over the course of the study. In the first, they sat for 14 hours with no exercise. In the second, participants sat for 13 hours and performed one hour of vigorous cycling. In the third, participants sat for eight hours, then walked for four hours and stood for another two, with energy expenditures matching the intense hour of cycling.
The researchers found that the subjects had improved insulin
sensitivity and lower cholesterol levels after walking and
standing compared to no exercise. And those subjects who walked
and stood also improved insulin sensitivity and reduced
cholesterol more than the intense exercise group.
"If you exercise for half an hour and are sedentary for the rest
of the day, that represents an unhealthy lifestyle," said
Savelberg. "Long periods of non-sitting at a low intensity level
should be classified as an active lifestyle."
Findings appeared online Wednesday in the peer-reviewed journal
PLOS One.
