Exercise
Next to diet, exercise is the most important
factor for achieving and maintaining optimum physical
health. It provides health benefits for people of all
ages and can also prolong life. A Finish study of nearly
8,000 men and women, for instance, found that those who
did not exercise increased their risk of dying by 400%
compared to individuals in the high-activity group. Here
are some tips to help you get started :
Frequency and duration of activity are
more important than intensity. Moderately intense exercise,
such as brisk walking, is enough for health benefits if
done most days of the week. Normal daily activities as
well as formal exercise sessions add up. You get health
benefits from walking up stairs and carrying out the trash,
gardening, cleaning, shopping, vacuuming, making the bed,
and mowing the lawn.
If you can, engage is moderate to vigorous
exercise using the large muscles for 30-60 minutes three
or more times a week; you're likely to gain even more
health benefits in addition to greater fitness.
You don't have to do all your exercise
at one time during the day. You can accumulate short periods
of moderately intense activity, such as mowing a patch
of lawn or walking up hills, in 5 - to 10-minute intervals
that total 30 minutes throughout the day. The key is the
total amount of energy expended not the intensity.
Strengthening exercises at least twice
a week help counteract muscle loss due to aging. And since
calories are burned more quickly by muscle tissue, muscle
mass is a key factor in helping maintain a healthful weight.
The more lean muscle mass you can preserve, the bigger
the "engine" in which to burn calories.
Ideally, you should have four goals for
your exercise regimen: aerobic capacity, strength, flexibility,
and weight control.
Plan a logical progression. If
you have unstable joints from injury or arthritis, or
you're in a weakened condition, start by improving your
muscle strength and flexibility. Build strength using
lighter weights and gently exercising the weakest parts
of your body.
When you're ready to add an aerobic exercise,
start at a comfortable level, such as walking 5-10 minutes
over a short distance indoors. Increase one to five minutes
per session, as tolerated.
Remember that for your fitness to improve,
you need to exercise regularly. Try for a minimum of 30
minutes of low to moderately intense physical activity
on most days of the week. Over time, you may be able to
build up to 30-60 minutes of moderate to vigorous exercise.
Include variety. Combine three types of
exercise - stretching (flexibility), endurance (aerobic),
and strengthening (weight training) - with three levels
of intensity - warm up, workout level, and cool-down-in
each exercise session. When you're fit, a typical session
might include a five minute warm-up, 20-40 minutes of
aerobic activity, 10-15 minutes of weight training, and
a five-minute cool-down of stretching.
Mixed training reduces your chance of injury to or overuse
of one specific muscle or joint. Alternative among exercises
that emphasize different part of your body.
Schedule time for recovery. Many people
start with frenzied zeal, exercising too long or too intensely,
and give up when muscles and joints become sore or injured.
Start slowly build up gradually, allowing time between
sessions for your body to rest and recover.
For most older people, brisk walking becomes
a mainstay exercise. Walking for 20-30 minutes or more
at least three but preferably five times a week offers
health benefits. If one of your goals is losing weight,
you may want to walk about 40 minutes several times a
week. That's because you burn more fat during longer-duration,
lower-intensity exercise than you do during shorter exercise
periods.
Precautions: Before beginning any exercise
program, consult your Physician and have a thorough exam
to rule out any health conditions that may need attention.
If you have heart disease, diabetes, or are at high risk
for these or other serious illness, begin an exercise
program only with your physician's approval. Inactive
men over the age of 40 and women over 50 should also consult
their physician. If you have been physically inactive
for some time, it is important to consult with your physician
to determine if you may need to undergo an accelerated
detoxification program before you begin exercising. Ask
your doctor how your medications may affect your exercise
plan. Drugs for diabetes, high blood pressure, and heart
disease, as well as sedatives, anti-histamines and cold
medications, can cause dehydration, impaired balance,
and blurred vision; in addition, some medications can
affect the way your body reacts to exercise.
