NOTE: Cybex does not recommend continuous holding onto the contact heart rate grips
during exercise.
Contaminants, such as hand lotions, oils or body powder, may come off on the contact heart
rate grips. These can reduce sensitivity and interfere with the heart rate signal. It is
recommended that the user have clean hands when using the contact heart rate.
Heart Rate Zone
Heart Rate is described by the number of
times your heart beats in a minute. At rest, the
average adult will have a heart rate of about
72 beats per minute (bpm). As one begins to
exercise, heart rate increases and continues
to increase as exercise intensity or difficulty
increases.
Monitoring your heart rate is an effective
way to control the intensity of your workout
and subsequently the results it will have.
Whether you are a new participant or one with
a great deal of experience, weight loss and
other performance goals can be achieved by
controlling the intensity of your workout.
The American College of Sports Medicine
recommends that healthy adults exercise
between 55 and 85% of their heart rate max.
Your heart rate max can be estimated by
subtracting your age from 220. Multiply that
estimated heart rate max by .55 to estimate
the lower end of your heart rate training zone.
Then multiply your estimated heart rate max by
.85 to estimate the higher end of your training
zone. This heart rate training zone gives you a
range of intensities at which to exercise.
NOTE: A label is located on the console to remind you what the heart rate zone is while you
are working out. See Figure 4.
Meaning of % Grade
A 1% grade is not the same as a 1 degree incline. The % grade is the relationship of the
measurement of rise over the measurement of run (also called slope). For example, a 1
foot (meter) rise in height over a length of 100 feet (meters) is a 1% grade. Expressed as a
mathematical formula, the grade is calculated as follows:
1 ft. (m) / 100 ft. (m) = 0.01 = 1%
With respect to treadmills, the percent grade is roughly equal to the increase in height (rise) of
the treadmill divided by the length (run) of the treadmill.
