HEART RATE Current Heart Rate (HR), in Beats Per Minute (BPM), is
displayed next to the heart icon on the lower display.
Percentage of Maximum HR - An approximation of maximal HR is calculated
based on the latest American College of Sports Medicine predictive equation as
follows:
Max Heart Rate = 215 – (Age * .75)
Percentage of maximum HR will only be shown in HRC programs.
Example: For a person 40 years of age, max HR is estimated as (215 – (40 (age) *
.75) = 185.
185 BPM would be the approximate maximum HR for a 40
-year-old user.
If the user works out at 140 BPM, then 76% (140 / 185 = 76%) will be
displayed in the upper left corner of the lower display area.
This means that the 40-year-old user working at 140 BPM is at 76% of
their maximum HR.
(See the Heart Training programs for more information.)
DISTANCE Provides a cumulative total of the equivalent distance, in
miles (or kilometers if your display is set to metric units),
you have traveled.
CALORIES Provides a current total of the number of calories burned
durin
g a workout.
Note: This number is only an approximation as a user’s
caloric expenditure will vary significantly based on a
person’s age, gender, weight and metabolism.
CALORIES/HOUR Provides the rate at which calories are burned per hour at
the current resistance level and steps per minute.
SPEED Displays the step rate in steps per minute (SPM).
User should consult a physician to determine an appropriate Target Heart
Rate (THR) in which to exercise, based on age, weight and physical
condition. Whi
le StairMaster
®
provides some THR ranges, these are only
approximations and should not be viewed as a medical recommendation.
