A NEW VIEW OF PHYSICAL
ACTIVITY:
This
report brings together, for the first time, what has been
learned about physical activity and health from decades of
research. Among its major findings:
-
People
who are usually inactive can improve their health and
well-being by becoming even moderately active on a regular
basis.
-
Physical
activity need not be strenuous to achieve health benefits.
-
Greater
health benefits can be achieved by increasing the amount
(duration, frequency, or intensity) of physical activity.
THE
BENEFITS OF REGULAR PHYSICAL ACTIVITY:
Regular
physical activity that is performed on most days of the week
reduces the risk of developing or dying from some of the leading
causes of illness and death in the United States. Regular
physical activity improves health in the following ways:
-
Reduces
the risk of dying prematurely.
-
Reduces
the risk of dying from heart disease.
-
Reduces
the risk of developing diabetes.
-
Reduces
the risk of developing high blood pressure.
-
Helps
reduce blood pressure in people who already have high blood
pressure.
-
Reduces
the risk of developing colon cancer.
-
Reduces
feelings of depression and anxiety.
-
Helps
control weight.
-
Helps
build and maintain healthy bones, muscles, and joints.
-
Helps
older adults become stronger and better able to move about
without falling.
-
Promotes
psychological well-being.
A
MAJOR PUBLIC HEALTH CONCERN:
Given
the numerous health benefits of physical activity, the hazards
of being inactive are clear. Physical inactivity is a serious,
nationwide problem. Its scope poses a public health challenge
for reducing the national burden of unnecessary illness and
premature death.
WHAT
IS A MODERATE AMOUNT OF PHYSICAL ACTIVITY?
As the
examples listed in the box show, a moderate amount of physical
activity* can be achieved in a variety of ways. People can
select activities that they enjoy and that fit into their daily
lives. Because amount of activity is a function of duration,
intensity, and frequency, the same amount of activity can be
obtained in longer sessions of moderately intense activities
(such as brisk walking) as in shorter sessions of more strenuous
activities (such as running): +
EXAMPLES
OF MODERATE AMOUNTS OF ACTIVITY:
|
Less
Vigorous, More Time
|
|
Washing
and waxing a car for 45-60 minutes
Washing windows or floors for 45-60 minutes
Playing volleyball for 45 minutes
Playing touch football for 30-45 minutes
Gardening for 30-45 minutes
Wheeling self in wheelchair for 30-40 minutes
Walking 1 3/4 miles in 35 minutes (20 min/mile)
Basketball (shooting baskets) for 30 minutes
Bicycling 5 miles in 30 minutes
Dancing fast (social) for 30 minutes
Pushing a stroller 1 1/2 miles in 30 minutes
Raking leaves for 30 minutes
Walking 2 miles in 30 minutes (15 min/mile)
Water aerobics for 30 minutes
Swimming laps for 20 minutes
Wheelchair basketball for 20 minutes
Basketball (playing a game) for 15-20 minutes
Bicycling 4 miles in 15 minutes
Jumping rope for 15 minutes
Running 1 1/2 miles in 15 minutes (10 min/mile)

More
Vigorous, Less Time

* A
moderate amount of physical activity is roughly equivalent to
physical activity that uses approximately 150 Calories (kcal) of
energy per day, or 1,000 Calories per week.
+ Some activities can be performed at various intensities; the
suggested durations correspond to expected intensity of effort.
PRECAUTIONS
FOR A HEALTHY START:
To
avoid soreness and injury, individuals contemplating an increase
in physical activity should start out slowly and gradually build
up to the desired amount to give the body time to adjust. People
with chronic health problems, such as heart disease, diabetes,
or obesity, or who are at high risk for these problems should
first consult a physician before beginning a new program of
physical activity. Also, men over age 40 and women over age 50
who plan to begin a new vigorous physical activity
program should consult a physician first to be sure they do not
have heart disease or other health problems.
STATUS
OF THE NATION - A NEED FOR CHANGE:
Adults
-
More
than 60 percent of adults do not achieve the recommended
amount of regular physical activity. In fact, 25 percent of
all adults are not active at all.
-
Inactivity
increases with age and is more common among women than men
and among those with lower income and less education than
among those with higher income or education

Adolescents
and Young Adults
-
Nearly
half of young people aged 12-21 are not vigorously active on
a regular basis.
-
Physical
activity declines dramatically with age during adolescence.
-
Female
adolescents are much less physically active than male
adolescents.
High School Students
-
In high school, enrollment in
daily physical education classes dropped from 42 percent in
1991 to 25 percent in 1995.
-
Only 19 percent of all high
school students are physically active for 20 minutes or more
in physical education classes every day during the school
week.
IDEAS FOR IMPROVEMENT:
This report identifies promising
ways to help people include more physical activity in their
daily lives.
-
Well-designed programs in
schools to increase physical activity in physical education
classes have been shown to be effective.
-
Carefully planned counseling
by health care providers and worksite activity programs can
increase individuals' physical activity levels.
-
Promising approaches being
tried in some communities around the nation include opening
school buildings and shopping malls for walking before or
after regular hours, as well as building bicycle and walking
paths separated from automobile traffic. Revising building
codes to require accessible stairwells is another idea that
has been suggested
SPECIAL MESSAGES FOR SPECIAL
POPULATIONS:
Older Adults
-
No one is too old to enjoy
the benefits of regular physical activity. Of special
interest to older adults is evidence that
muscle-strengthening exercises can reduce the risk of
falling and fracturing bones and can improve the ability to
live independently.
Parents
-
Parents can help their
children maintain a physically active lifestyle by providing
encouragement and opportunities for physical activity.
Family events can include opportunities for everyone in the
family to be active.
Teenagers
-
Regular physical activity
improves strength, builds lean muscle, and decreases body
fat. It can build stronger bones to last a lifetime.
Dieters
-
Regular physical activity
burns Calories and preserves lean muscle mass. It is a key
component of any weight loss effort and is important for
controlling weight.
People with High Blood
Pressure
Regular physical activity helps
lower blood pressure.
People Feeling Anxious,
Depressed, or Moody
Regular physical activity improves mood, helps
relieve depression, and
increases feelings of well-being.
People with Arthritis
Regular physical activity can help
control joint swelling
and pain. Physical
activity of the type and amount
recommended for
health has not been shown to cause
arthritis.
People with Disabilities
Regular physical activity can help people with chronic,
disabling conditions
improve their stamina and muscle
strength and can
improve psychological well-being and
quality of life by
increasing the ability to perform
activities of daily
life.

Keep Active - Safe at any Age
|
Exercise helps you feel better because it improves your
health. Orthopaedic surgeons say that by spending a little
time each day in some type of physical activity, you can
enjoy these significant benefits:
- longer, healthier life
- stronger bones
- reduced joint and muscle pain
- improved mobility and balance
- lower risk of falls and serious injuries like hip
fractures
- slower loss of muscle mass
People are living longer these days and their quality of
life depends on being healthy and remaining independent.
Staying active can lower your risk for many common diseases,
relieve the pain of arthritis and help you to recover faster
when you do get sick.
