Heart Rate—Current heart rate, in beats per minute, is displayed next to the
heart icon on the lower display.
Percentage of Maximum Heart Rate—An approximation of maximal heart
rate is calculated based on the latest American College of Sports Medicine
predictive equation as follows:
Max Heart Rate = 215 – (Age * .75)
Percentage of maximum heart rate 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 beats per minute would be the approximate maximum heart rate for a 40-
year-old user. If the user works out at 140 beats per minute, 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 beats per minute is at 76%
of their maximum heart rate.
(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 during
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 RPM.
Speed— Displays the speed in in miles per hour (or kilometers per hour).
RPM— Displays the pedal revolutions per minute.
Watts—During a workout, this statistic displays the power output at the
current RPM and intensity Level, displayed in watts (746 watts = 1 hp).
METs—Gives you the relative energy cost of exercise. MET stands for
multiple of the resting metabolic rate. While you are sitting quietly, your body
consumes oxygen at the rate of 1 MET or about 3.5 milliliters per kilogram of
body mass per minute. When you exercise, your body needs more oxygen in
order to function. For example, exercising at 10 METs requires ten times the
resting rate of oxygen consumption, or about 35 milliliters per kilogram per
minute. During a workout, the display shows the current MET level. During
the workout summary, the average MET level is displayed. During your
User should consult a physician to
determine an appropriate target
heart rate in which to exercise in
based on age, weight and physical
condition. While Nautilus provides
some target heart rate ranges,
these are only approximations and
should not be viewed as a medical
recommendation.
