Walking Does Wonders For Your Health
These days, it's easy for people to get confused about exercise
-- how many minutes a day should they spend working out, for how
long and at what exertion level? Conflicting facts and opinions
abound, but one Mayo Clinic physician says the bottom line is
this: walking is good, whether the outcome measurement is blood
pressure, diabetes, cardiovascular disease, joint problems or
mental health.
"Getting out there and taking a walk
is what it's all about," says James Levine, M.D., Ph.D., and
a Mayo Clinic expert on obesity. "You don't have to join a
gym, you don't have to check your pulse. You just have to switch
off the TV, get off the sofa and go for a walk."
The health benefit associated with walking is the subject of
Dr. Levine's editorial in the July issue of Mayo Clinic Proceedings.
Dr. Levine's piece is entitled, "Exercise: A Walk in the
Park?" and accompanies a Proceedings article that showcases
the merits of walking as beneficial exercise.
The study, undertaken by physicians from the Shinshu University
Graduate School of Medicine in Matsumoto, Japan, determined that
high-intensity interval walking may protect against high blood
pressure and decreased muscle strength among older people.
Over five months, the Japanese researchers studied 246 adults
who engaged in either no walking or moderate to high-intensity
walking. The group who engaged in high-intensity walking experienced
the most significant improvement in their health, the researchers
found. In his editorial, Dr. Levine says the study lends credence
to the notion that walking is a legitimate, worthy mode of exercise
for all people. Dr. Levine says it's a welcome message for his
patients, who fight obesity and appreciate that a walk is one
way to improve their health.
Unlike a health club membership or personal trainer, walking
"is there for everyone," Dr. Levine says. "Walking
doesn't cost you anything, you can do it barefoot and you can
do it now, this minute."
"Sitting is bad for cholesterol, it's bad for your back
and muscles," Dr. Levine says. "It's such a terrible
thing for our bodies to do and the less of it you do, the better.
But activity is not easy. If it were easy, everyone would do it."
