With the Gerkin protocol there is a tiered VO2 test with submaximal values. It is used by
the International Association of Fire Fighters to determine fitness for service with the fire
department.
Set the values for your age and gender using the number keys or the FAST/SLOW keys.
Scroll to change fields. Press ENTER to start the program. During the test, do not manu-
ally change the speed or incline, as this will make the test invalid. This test calculates the
user’s fitness when the heart rate stabilizes at ____ BPM and the program terminates.
Press FAST to start.
FITNESS TEST PROTOCOL WORKSHEET:
__________________________________
Resting heart rate (BPM):
Training target heart rate
(85% of HRmax):
_______________
IF AT ANY TIME DURING A TEST THE USER EXPERIENCES CHEST PAIN,
DIZZINESS, ATAXIA, CONFUSION, NAUSEA, OR COLD SWEAT, END THE
TEST IMMEDIATELY!
Place the heart rate device on the user.
The user’s heart rate is to be measured continuously throughout the test and in the
cool-down phase. The heart rate is retrieved and recorded during the last 15 sec-
onds of each phase.
If the heart rate of the person exceeds the target training heart rate, continue the
test in the phase in which the target training heart rate was exceeded for an addi-
tional 15 seconds.
The test is completed and the final testing phase is given if the heart rate does not
return to the target training heart rate (or a lower value) or when the person
reaches phase 11.4.
The VO2max is determined using the heart rate retrieved during the final test
phase and the conversion table.
Record the heart rate after a one minute cool-down.
