Keep Active
Accumulate at least 30 minutes of moderate activity each day. To best
help your heart, exercise continuously for 20-45 minutes, three to five
days a week.
Why should I exercise?
Keeping your body moving lowers the risk of heart disease. Regular
activity can help to lower blood pressure, improve cholesterol levels and
maintain a healthy weight.
What's the difference between
"accumulating 30 minutes of activity" and "exercising
continuously for 20-40 minutes?"
It is recommended that all Americans accumulate at least 30 minutes of
moderate activity on most, if not all, days of the week. Moderate activity
is anything that gets you up and moving, such as walking, gardening or
dancing. The important point is to choose an activity that you enjoy and
do it regularly. The duration of the activity can be broken up into
several shorter sessions: walk the dog for 10 minutes in the morning,
garden 10 minutes in the afternoon and take a walk for 10 minutes after
dinner.
While a program of moderate activity can bring many health benefits,
strenuous exercise, called aerobic exercise, can lead to much greater
improvements in heart health. Aerobic exercise is any activity that
increases your heart rate and breathing rate. Examples include power
walking, cycling, tennis, running, basketball, swimming and soccer. For
the best heart benefits, aerobic exercise should be done continuously for
20-45 minutes, three to five days per week. Do some light activity before
the exercise to warm up the muscles, tendons and joints. After exercise,
walk slowly for a few minutes to allow your heart rate to return to
normal.
Are there also advantages to strength training
and stretching exercises?
Strength training is an important part of an exercise program. Strength
training strengthens both muscles and bones, and helps joints work more
smoothly. In addition, increasing the amount of muscle you have can help
with weight loss by increasing your metabolic rate. You can use different
types of equipment, such as light dumbbells, free weights or machines at
health clubs. Exercises such as push-ups or curlups, which use your body's
own weight, also strengthen muscles.
To lower the risk of muscle and joint injuries, stretching should be
part of any exercise program. Do your stretching after exercising, after
your muscles have been warmed up. Stretching cold muscles often leads to
injuries. Hold each stretch for at least 30 seconds. If a stretch is
painful, ease up until just some tension is felt in the muscle.
I have bad knees and a bad back. Are there any
exercises that I can do?
People with medical problems can do many exercises safely. Bicycling
and swimming are great choices for people with joint problems. There also
are exercises that can be done in a chair. Many senior centers hold
special "chair aerobics" classes and there are several chair
aerobic videos available.
What can I do?
- Get an OK from your doctor before starting any new exercise
program.
- Find a friend who is interested in activity and plan to attend a
fitness class or go for a walk three to four times a week.
- Park several blocks from work or the store to add extra minutes of
walking to your daily routine.
- Take the stairs instead of the elevator when possible.
- Walk your dog daily.
- Join a fitness group - at the senior center, cardiac rehabilitation
program, local pool, mall walking program, YMCA, karate or fitness
center.
- Try square dancing, line dancing or ballroom dancing.
- Calculate the calories burned per hour
based on activity.
