Interval (INTV) Program
The Interval Program is among the best for conditioning your
cardiovascular system. Each 1-minute interval raises and lowers your
level of exertion repeatedly throughout the duration of the program.
When you begin the program, the incline and speed settings are
preprogrammed. To change the settings, press the appropriate arrow
key and continue. The changes are applied to the remaining intervals.
The display lets you know when the incline or speed levels are about
to change, and indicates the levels of the next interval.
When you complete the program, any changes made to the incline
and speed settings are not saved.
Fitness (FIT) Test
The Fitness Test provides a means of comparing your fitness level with
the official fitness test of the International Association of Firefighters
(IAFF). It is written using the Gerkin Protocol, which is the basis for the
official IAFF fitness test and part of their Wellness and Fitness
Initiative.
During the test, the treadmill gradually increases the incline and speed
in specific stages. The test ends when you surpass your target heart
rate (85% of your maximum heart rate) or complete the 13-minute
time limit. Whatever stage you are at when the test ends determines
your aerobic capacity and establishes your VO2 max.
VO2 max is a health and fitness term meaning the maximum amount of
oxygen the body can use for energy production during exercise. It
provides an index or fitness level based on the following rule: the
higher the amount of oxygen that your body can use, the greater your
ability to exercise for prolonged periods of time.
