HEART RATE EXERTION
The two most popular reasons for, or goals, of exercise are cardiovascular
tness (training for the heart and lungs) and weight control. The black
columns on the chart represent the MHR for a person whose age is
listed at the bottom of each column. The training heart rate, for either
cardiovascular tness or weight loss, is represented by two dierent lines
that cut diagonally through the chart. A denition of the lines’ goal is in
the bottom left-hand corner of the chart. If your goal is cardiovascular
tness or if it is weight loss, it can be achieved by training at 80% or 60%,
respectively, of your MHR on a schedule approved by your physician.
Consult your physician before participating in any exercise program.
With all Heart Rate program you may use the heart rate monitor feature
without using the Heart Rate program. This function can be used during
manual mode or during any of the nine dierent programs.
The old motto, “no pain, no gain”, is a myth that has been
overpowered by the benets of exercising comfortably. A great deal
of this success has been promoted by the use of heart rate monitors.
With the proper use of a heart rate monitor, many people nd that
their usual choice of exercise intensity was either too high or too low
and exercise is much more enjoyable by maintaining their heart rate in
the desired benet range.
To determine the benet range in which you wish to train, you must
rst determine your Maximum Heart Rate. This can be accomplished
by using the following formula: 220 minus your age. This will give
you the Maximum Heart Rate (MHR)for someone of your age. To
determine the eective heart rate range for specic goals you simply
calculate a percentage of your MHR. Your Heart rate training zone
is 50% to 90% of your maximum heart rate. 60% of your MHR is
the recommended for burning fat while 80% is recommended for
strengthening the cardio vascular system. This 60% to 80% is the
zone to stay in for maximum benet.
For someone who is 40 years old their
target heart rate zone is calculated:
220 – 40 = 180 (maximum heart rate)
180 x .6 = 108 beats per minute (60% of maximum)
180 X .8 = 144 beats per minute (80% of maximum)
So for a 40 year old the training zone would
be 108 to 144 beats per minute.
If you enter your age during programming the console will perform
this calculation automatically. Entering your age is used for the Heart
Rate programs. After calculating your MHR you can decide upon
which goal you would like to pursue.
