Pedometers Tested As
Step to More Exercise
Can an inexpensive device that clips
onto your belt and tracks your steps really turn a nation of exercise
slouches into healthier, more active adults?
Some researchers think so, and
so do the organizers of a campaign called America on the Move,
launched this summer to encourage inactive Americans to clip on
a pedometer and log an extra 2,000 steps a day to start.
More recently, McDonald's has joined
the party, passing out pedometers with its Go Active Meal, now
being test marketed in Indiana.
The premise is simple: If your
idea of exercise is changing channels manually, grab a pedometer,
clip it on, and try to walk an extra 2,000 steps a day.
It won't turn you into a buffed
person -- or even a super fit one -- as the organizers of the
America on the Move program concede. But it's meant as a first
step, says Wendy Artman, a spokeswoman for the campaign.
You might just catch the exercise
habit.
And if enough people do it, it
might help stem the tide of inactivity and the growing epidemic
of obesity, they say. From 1988 to 1994, the percent of U.S. adults
classified as obese rose from 23 percent to 31 percent, according
to the officials at America on the Move, citing government statistics.
Only 26.2 percent of the U.S. population
gets the recommended amount of exercise -- that means 30 minutes
of physical activity (the equivalent of 3,000 to 4,000 steps)
most days of the week. And nearly 28 percent are inactive. Another
46 percent get inadequate amounts of activity, according to the
U.S. Centers for Disease Control and Prevention.
Moving a little more and eating
a little less can help, public health officials say.
And McDonald's marketers agree.
Its $5 Get Active meal, which includes a meal-sized salad
with chicken or beef, bottled water, a pedometer and an exercise
booklet, is being test marketed in Indiana. If all goes well,
the meal will be offered nationwide in 2004, says company spokeswoman
Bridget Coffing.
There's no connection between the
new Go Active meal and the obesity lawsuit filed against McDonald's
that was dismissed recently, Coffing says, citing a "rich
tradition" by the company of sponsoring community programs
that encourage activity.
Research suggests the devices do
help people get active.
In one study, researchers evaluated
nine overweight people with type 2 diabetes who were sedentary
and then were given pedometers. They increased their walking,
with the average walk time rising to 34.3 minutes daily. They
kept it up even two months after the study, although their total
walk time dropped to 22.6 minutes a day. That research appeared
in the May 2002 issue of Patient Education and Counseling.
David Bassett Jr., a researcher
at the University of Tennessee in Knoxville, also believes in
the value of the devices. "You can put them on and easily
get feedback about how active you are," he says. They work
best, he says, "for people at the lower end of the activity
spectrum."
Response to America on the Move
has been great since the launch, Artman says. Besides the hundreds
of information requests, Indiana has launched Indiana on the Move,
a program similar to Colorado on the Move, the pilot program that
sparked the national effort.
Pedometers are readily available
for as little as $20 or less, although some models cost more,
either at sporting goods stores or online from organizations such
as America on the Move. Bassett and his colleagues recently evaluated
10 pedometers and found they are less accurate at slower walking
speeds.
Of the 10 devices tested, they
found the Yamax Digiwalker SW-701 the most accurate at calculating
steps, distance and calories burned. The runner-up was the Walk4Life
LS 2525.
