The Workout Profile; Mets; Meaning Of % Grade - CYBEX PRO3 Owner's Manual

The Workout Profile

The Workout Profi le matrix in the center of the display uses columns of lights to show the progress of
your workout. The height of the column represents METS, specifi cally the highest METS you reached in
that period. Each column represents 1 minute of your total workout time when in Manual Mode and 15
seconds in every other program.
NOTE: It is conceivable to have two segments of different speed and elevation combinations in the same
met range.

METs

A MET is a basic unit of measurement that is used to compare relative work between individuals and
activities. One MET is the amount of oxygen an individual consumes at rest. If an individual were working
at four METs he/she would be consuming oxygen at a rate equal to four times their resting consumption.
METs can be used to compare walking on a grade with running or even to cycling and other activities.

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.
The degree of incline can be related to % grade by taking the Tangent of the grade. For instance, 15%
grade is equal to 8.53 Degrees (Tan(.15)=8.53º). The opposite is true to determine % Grade from Degree
of incline (ArcTan (8.53º)=.15).
