CONSOLE OPERATION
P-12 CONSTANT HEART RATE PROGRAM
Illustrations of the programs are shown on page 32.
•
For safety reasons the user must exercise at below 85% of the maximum heart rate.
•
To prevent injuries, do a brief warm-up session before doing this test.
•
The pulse rate must be measured by a telemetric chest band such as the Polar T41
transmitter . If the heart rate is not measured, then the heart symbol and a question mark
“ ♥ ?” appear on the screen. If the unit continues not to receive any heart rate information,
then the program will be cancelled and another program will have to be selected.
•
Before beginning the test, calculate your maximum heart rate. The maximum number of
heartbeats that a person must not exceed is referred to as the maximum heart rate and this
value drops with age. A simple formula to calculate this is to subtract your age, in years,
from the number 220. To ensure that you are exercising correctly, try to keep between 65%
and 85% of your maximum heart rate value.
For example, the maximum heart rate that a 30 year old user must not exceed is:
220 – 30 = 190 heart beats per minute (BPM).
190 x 0.65 = 123 heart beats per minute.
190 x 0.85 = 161 heart beats per minute.
So the heart rate exercise range for a 30 year old is between 123 and 161 BPM.
•
This program allows the user to enter a value for the heart rate (between 65% and 85% of
the maximum heart rate) and the machine will automatically adjust exertion levels to ensure
that the user maintains the selected heart rate value.
•
The value (in seconds) entered into the (Personalizing the Electronic Monitor) “SPR TIME”
tells the software how often to calculate the users heart beats per minute (BPM) during this
test. The software will increase or decrease the resistance to control the heart BPM.
With the monitor switched on, the top LED array ( A ), Figure 21, will display the profile and the
letter “M” for manual. Use the LEVEL
▲▼ keys to select the ♥ (P12 HEART) program. Press
the ENTER key.
