Regular exercise is good for your health. A moderate amount of
activity performed three to five days per week can:
-
Improve your heart
health
-
Improve your heart
disease risk factors
-
Improve your strength
and feeling of well-being
Improve your heart
health:
-
Reduce the risk of
dying from heart disease
-
Help your heart and
cardiovascular system work more efficiently
-
Decrease symptoms of
angina (chest discomfort) and heart failure
Improve your heart
disease risk factors
-
Reduce risk of developing
diabetes and high blood pressure
-
Improve blood sugar
tolerance if you have diabetes
-
Help control high blood
pressure, by as much as 8 to 10 points in both systolic and
diastolic pressure.
-
Improve blood lipids
(cholesterol, LDL, HDL and triglycerides) along with other strategies
(diet and medications).
-
Support efforts to
stop smoking
-
Control weight and
reduce body fat
Improve your strength and feeling
of well-being:
- Helps keep muscles, bones, and joints
healthy
- Increase your ability to do daily activities
without getting tired
- Improve your balance and flexibility
- Maintain muscle tone, improve your posture,
and reduce the risk of falling and fracturing bones
- Lessen feelings of anxiety or depression
- Improve your sense of well-being and help
you feel good about yourself
To be safe and give you the most
benefit, your program should be:
- Aerobic: this type of
activity increases the rate and depth of your breathing, raises
your heart rate and uses the large muscle groups. Examples include
walking, cycling or swimming.
- Regular: moderate intensity
activity performed on most days of the week (starting with small
amounts of activity and building up to 30 to 40 minutes of continuous
activity, or if you prefer, 10 minutes increments throughout the
day to equal 30 to 40 minutes
- Safe: adults with health
problems (such as heart disease, diabetes or obesity) or those
at high risk, men over age 40 and women over age 50 should talk
with their doctor before starting an exercise program.
Three phases of exercise:
Like a recipe, these three phases are the essential ingredients
of your exercise session:
1. The warm-up
This phase helps you move from rest to activity. Just as you allow
a car to warm up when the engine is cold to prevent damage to the
motor, a warm-up lessens the stress placed on your heart and muscles.
The warm-up helps to slowly increase breathing, heart rate and body
temperature. It also helps to improve flexibility and reduce muscle
soreness.
The warm-up may include:
- Stretching exercises
- Range of motion activities
- Your exercise activity at a very low intensity
(for example, walking at a very slow pace)
For the best effects on your muscles and
cardiovascular system, your warm-up should last about five to
15 minutes.
2. Conditioning
This phase follows the warm-up and provides you with the benefits
of exercise. For the best results, remember these four important
points in your Conditioning Phase:
-
Frequency:
how often you need to exercise
Exercise on most days of the week
-
Intensity:
how vigorous you need to exercise
Moderate intensity – enough to get your heart rate and
breathing to increase
-
Duration:
how long you need to exercise
30 to 40 minutes of continuous exercise OR 10 minute increments
to equal 30 to 40 minutes throughout the day.
If you haven’t exercised in a while,
your heart, lungs, and muscles will need to work up to your exercise
duration. Begin with shorter bouts of exercise, about 15 minutes
or so, every other day. Progress by three to five minute increments
per week until you reach your goal of 30 to 40 minutes on most days.
Type – the type of activity that will give you the desired
results.
Exercise must involve the large muscle groups. You can vary your
routine by engaging in more than one activity. A combination of
walking, swimming, and cycling strengthens several muscle groups
and will prevent you from becoming bored.
3. Cool-down
This last phase allows your body to recover from the conditioning
phase. Heart rate and blood pressure will return to near resting
values. Cool-down does not mean sit down! In fact you should not
stand still, sit or lie down right after exercise. This may cause
you to feel dizzy, lightheaded or have palpitations.
During Cool-down:
- Slowly decrease the intensity of your
activity
- Perform the stretching and range of motion
exercises from your warm-up phase
Like the warm-up phase, the cool-down should
last about five to 15 minutes for the best results.
Include all three phases in your exercise session to avoid injury
and problems during exercise. Always consult a doctor before beginning
any strenuous exercise program.
