Subject: Aerobic Exercise
Aerobic activity is an important addition to moderate-intensity
exercise. Aerobic exercise is any extended activity that makes
you breathe hard while using the large muscle groups at a
regular, even pace. Aerobic activities help make your heart
stronger and more efficient. They also use more calories than
other activities. Some examples of aerobic activities include:
- Brisk walking
- Jogging
- Bicycling
- Swimming
- Aerobic dancing
- Racket sports
- Rowing
- Ice or roller skating
- Cross-country or downhill skiing
- Using aerobic equipment (i.e., treadmill, stationary bike)
To get the most health benefits from aerobic activity, you should
exercise at a level strenuous enough to raise your heart rate to
your target heart-rate zone.
Your target heart rate zone is 50 to 75 percent of your maximum
heart rate (the fastest your heart can beat). To find your target
zone, look for the category closest to your age in the chart
below and read across the line.
Example
If you are 35 years old, your target heart rate zone is 93-138
beats per minute.
Exercise heart-rate chart
Age
Target Heart Rate Zone
(50-75% of average maximum rate)
20-30
98-146 beats per min
31-40
93-138 beats per min
41-50
88-131 beats per min
51-60
83-123 beats per min
61+
78-116 beats per min
Check to see if you're in your ZONE
To see if you are exercising within your target heart rate zone, count
the number of pulse beats at your wrist or neck for 15 seconds, then
multiply by four to get the beats per minute. Your heart should be
beating within your target heart rate zone. If your heart is beating
faster than your target heart rate, you are exercising too hard and
should slow down. If your heart is beating slower than your target
heart rate, you should exercise a little harder.
Go easy!
When you begin your exercise program, aim for the lower part of your
target zone (50 percent). As you get into better shape, slowly build
up to the higher part of your target zone (75 percent). If exercising
within your target zone seems too hard, exercise at a pace that is
comfortable for you. You will find that, with time, you will feel
more comfortable exercising and can slowly increase to your target
zone.
Even low to moderately intensive activity can help lower the risk of
heart disease. Examples of such activity are pleasure walking, stair
climbing, gardening, yard work, moderate-to-heavy housework, dancing,
and home exercise. To get heart benefits from these activities, do
one or more of them every day. |
