Heart Rate
speed interval
The Heart Rate Speed Interval program focuses on power and speed using
alternating one-minute intervals of
65%
and
85%
of your theoretical maximum
heart rate (TMHR). It combines steeper (higher resistance) intervals with
changing speeds.
Use the Program (+/–) keys and Enter to select the program,
then use the appropriate (+/–) keys to enter the program settings as prompted:
Workout Time, Age, Max Target Heart Rate (defaults to 85% of your TMHR),
and Weight. The computer sets your initial Low (65%) Target Heart Rate value
relative to the value you enter for the Max Target Heart Rate. The program
begins with a warm-up. If you reach your target heart rate during the warm-up,
the warm-up ends and the heart rate control portion begins. The resistance
increases or decreases at the end of each one-minute period to get you to the
next interval. When you reach the new target heart rate, the new one-minute
interval begins. The display will prompt you to increase or decrease your effort
until the desired heart rate is reached. The better your physical condition, the
more intervals you will be able to accomplish in the same period of time. At
any time during the program you can change the target heart rate of the current
interval using the Level (+/–) keys on the keypad.
Example for a 40-year-old person:
220 – 40 yrs. old = 180 TMHR
180 * .65 = 117 Low interval target heart rate
180 * .85 = 153 High interval target heart rate
