Walking
is easily the most popular form of exercise. Other activities
generate more conversation and media coverage, but none of
them approaches walking in number of participants.
Approximately half of the 165 million American adults (18 years of age
and older) claim they exercise regularly, and the number who
walk for exercise is increasing every day.
Walking is
the only exercise in which the rate of participation does not
decline in the middle and later years. In a national survey,
the highest percentage of regular walkers (39.4%) for any
group was found among men 65 years of age and older.
Walking today
is riding a wave of popularity that draws its strength from a
rediscovery of walking's utility, pleasures, and health-giving
qualities. This page is for those who want to join that
movement.
Walking: The
Slower, Surer Way to Fitness
People walk
for many reasons: for pleasure...to rid themselves of
tensions...to find solitude...or to get from one place to
another. Nearly everyone who walks regularly does so at least
in part because of a conviction that it is good exercise.
Often
dismissed in the past as being "too easy" to be
taken seriously, walking recently has gained new respect as a
means of improving physical fitness. Studies show that, when
done briskly on a regular schedule, it can improve the body's
ability to consume oxygen during exertion, lower the resting
heart rate, reduce blood pressure, and increase the efficiency
of the heart and lungs. It also helps burn excess calories.
Since obesity
and high blood pressure are among the leading risk factors for
heart attack and stroke, walking offers protection against two
of our major killers.
Walking burns
approximately the same amount of calories per mile as does
running, a fact particularly appealing to those who find it
difficult to sustain the jarring effects of long distance
jogging. Brisk walking one mile in 15 minutes burns just about
the same number of calories as jogging an equal distance in 8
1/2 minutes. In weight-bearing activities like walking,
heavier individuals will burn more calories than lighter
persons. For example, studies show that a 110-pound person
burns about half as many calories as a 216 pound person
walking at the same pace for the same distance.
Although
increasing walking speed does not burn significantly more
calories per mile, a more vigorous walking pace will produce
more dramatic conditioning effects. When looking at the
benefits to heart/lung endurance, how far one improves depends
on his/her initial fitness level. Someone starting out in poor
shape will benefit from a slow speed of walking whereby
someone in better condition would need to walk faster and/or
farther to improve. Recent studies show that there are also
residual benefits to vigorous exercise. For a period of time
after a dynamic workout, one's metabolism remains elevated
above normal which results in additional calories burned.
In some
weight-loss and conditioning studies, walking actually has
proven to be more effective than running and other more
highly-touted activities. That's because it's virtually
injury-free and has the lowest dropout rate of any form of
exercise.
Like other
forms of exercise, walking appears to have a substantial
psychological payoff. Beginning walkers almost invariably
report that they feel better and sleep better, and that their
mental outlook improves.
In addition
to the qualities it has in common with other activities,
walking has several unique advantages. Some of these are:
- Almost
everyone can do it. You don't have to take lessons to learn
how to walk. Probably all you need to do to become a serious
walker is step up your pace and distance and walk more often.
- You can do it
almost anywhere. All you have to do to find a place to walk is
step outside your door. Almost any sidewalk, street, road,
trail, park, field, or shopping mall will do. The variety of
settings available is one of the things that makes walking
such a practical and pleasurable activity.
- You can do it
almost anytime. You don't have to find a partner or get a team
together to walk, so you can set your own schedule. Weather
doesn't pose the same problems and uncertainties that it does
in many sports. Walking is not a seasonal activity, and you
can do it in extreme temperatures that would rule out other
activities.
- It doesn't
cost anything. You don't have to pay fees or join a private
club to become a walker. The only equipment required is a
sturdy, comfortable pair of shoes.
Walking For
Physical Fitness
What makes a
walk a workout? It's largely a matter of pace and distance.
When you're walking for exercise, you don't saunter, stroll,
or shuffle. Instead, you move out at a steady clip that is
brisk enough to make your heart beat faster and cause you to
breathe more deeply.
Here are some
tips to help you develop an efficient walking style:
- Hold head
erect and keep back straight and abdomen flat. Toes should
point straight ahead and arms should swing loosely at sides.
- Land on the
heel of the foot and roll forward to drive off the ball of the
foot. Walking only on the ball of the foot, or in a
flat-footed style, may cause fatigue and soreness.
- Take long,
easy strides, but don't strain for distance. When walking up
or down hills, or at a very rapid pace, lean forward slightly.
- Breathe
deeply (with mouth open, if that is more comfortable).
What to Wear
When Walking
A good pair
of shoes is the only "special equipment" required by
the walker. Any shoes that are comfortable, provide good
support, and don't cause blisters or calluses will do, but
here are some suggestions to help you make your selection:
- Good running
shoes (the training models with heavy soles) are good walking
shoes, as are some of the lighter trail and hiking boots and
casual shoes with heavy rubber or crepe rubber soles.
- Whatever
kind of shoe you select, it should have arch supports and
should elevate the heel one-half to three-quarters of an inch
above the sole of the foot.
- Choose a
shoe with uppers made of materials that "breathe,"
such as leather or nylon mesh.
Weather will
dictate the rest of your attire. As a general rule, you will
want to wear lighter clothing than temperatures seem to
indicate. Walking generates lots of body heat.
In cold
weather, it's better to wear several layers of light clothing
than one or two heavy layers. The extra layers help trap heat,
and they are easy to shed if you get too warm. A wool watch
cap or ski cap also will help trap body head and provide
protection for the head in very cold temperatures.
Walking Poses
Few Health Risks
If you are
free of serious health problems, you can start walking with
confidence. Walking is not as strenuous as running, bicycling,
or swimming and consequently involves almost no risk to
health. Of course, this statement assumes that you will
exercise good judgment and not try to exceed the limits of
your condition.
Most
physicians recommend annual physical examinations for persons
over 40 or 45 years of age. Also, if you have high blood
pressure or other cardiovascular problems, you should consult
your physician before beginning any kind of exercise program.
Warm-up and
Conditioning Exercises
Walking is
good exercise for the legs, heart, and lungs, but it is not a
complete exercise program. Persons who limit themselves to
walking tend to become stiff and inflexible, with short, tight
muscles in the back and backs of the legs. They also may lack
muscle tone and strength in the trunk and upper body. These
conditions can lead to poor posture and chronic lower-back
pain, a problem that partially cripples or disables thousands
of middle-aged and older Americans.
The exercises
that follow are designed to increase flexibility and strength
and to serve as a "warm-up" for walking. Always do
the exercises before walking.
- Stretcher.
Stand facing wall arms' length away. Lean forward and place
palms of hands flat against wall, slightly below shoulder
height. Keep back straight, heels firmly on floor, and slowly
bend elbows until forehead touches wall. Tuck hips toward wall
and hold position for 20 seconds. Repeat exercise with knees
slightly flexed.
- Reach and
Bend. Stand erect with feet shoulder width apart and arms
extended over head. Reach as high as possible while keeping
heels on floor and hold for 10 counts. Flex knees slightly and
bend slowly at waist, touching floor between feet with
fingers. Hold for 10 counts. (If you can't touch the floor,
try to touch the tops of your shoes.) Repeat entire sequence 2
to 5 times.
- Knee
Pull.
Lie flat on back with legs extended and arms at sides. Lock
arms around legs just below knees and pull knees to chest,
raising buttocks slightly off floor. Hold for 10 to 15 counts.
(If you have knee problems, you may find it easier to lock
arms behind knees.) Repeat exercise 3 to 5 times.
- Sit-ups. Start with the
sit-ups that you can do three times
without undue strain. When you are able to do 10 repetitions
of the exercise without great difficulty, move on to a more
difficult version.
How
Far?...How Fast?...How Soon?
Now that you
have decided to begin walking for exercise, you may be shocked
at how poor your condition is. If at first you have difficulty
in meeting the standards suggested here, don't be discouraged.
You can systematically build your stamina and strength back to
acceptable levels. Patience is the key to success. Some
experts say that it takes a month of reconditioning to make up
for each year of physical inactivity.
No one can
tell you exactly how far or how fast to walk at the start, but
you can determine the proper pace and distance by
experimenting. We recommend that you begin by walking for 20
minutes at least four or five times a week at a pace that
feels comfortable to you. If that proves to be too tiring, or
too easy, reduce or lengthen your time accordingly.
Some very old
people and some people who are ill begin by walking for one or
two minutes, resting a minute, and repeating this cycle until
they begin to be fatigued. Where you have to start isn't
important; it's where you're going that counts.
As your
condition improves, you should gradually increase your time
and pace. After you have been walking for 20 minutes several
days a week for one month, start walking 30 minutes per
outing. Eventually your goal should be to get to the place
where you can comfortably walk three miles in 45 minutes, but
there is no hurry about getting there.
The speed at
which you walk is less important that the time you devote to
it, although we recommend that you walk as briskly as your
condition permits. It takes about 20 minutes for your body to
begin realizing the "training effects" of sustained
exercise.
The
"talk test" can help you find the right pace. You
should be able to carry on a conversation while walking. If
you're too breathless to talk, you're going too fast.
The more
often you walk, the faster you will improve. Three workouts a
week are considered to be a "maintenance level" of
exercise. More frequent workouts are required for swift
improvement.
Listen to
Your Body
Listen to
your body when you walk. If you develop dizziness, pain,
nausea, or any other unusual symptom, slow down or stop. If
the problem persists, see your physician before walking again.
Don't try to
compete with others when walking. Even individuals of similar
age and build vary widely in their capacity for exercise. Your
objective should be to steadily improve your own performance,
not to walk farther or faster than someone else.
The most
important thing is simply to set aside part of each day and
walk. No matter what your age or condition, it's a practice
that can make you healthier and happier.
Before
undertaking any physical activity program, you should have a
thorough medical examination. This is especially important for
persons over 40 or for anyone who has not been physically
active on a regular basis.
