7.2.2 YMCA protocol ”Y’s way to physical fit-
ness”
The YMCA protocol is based on the “Y´s Way
to Physical Fitness” bicycle test. The design is a
submaximal test, using branching multiple wor-
kloads in which the next workload is determined
by the steady state heart rate elicited by the pre-
vious level. For details, refer to the “ Workload
Branching” tables, later in this section.
Every three minutes the workload is advanced
until the subject has completed three levels, requi-
ring a total of nine minutes. If the subject has an
abnormally high heart rate response to the initial
workload (100 bpm or more), the test is termina-
ted at the end of the second level. If the operator
senses that the subject is experiencing difficulty
completing the third level of the protocol, the
START/STOP key may be used to conclude the
test early. If the test is stopped prior to the com-
pletion of the second level, an error message is
displayed, indicating that the test was “aborted”
and no calculation of V02 max is possible.
At the conclusion of the test, estimates of the V02
max and the maximum workload are extrapola-
ted from the data collected during the previous
two levels. The V02 max is reported on the dis-
play and the maximum workload contained in
the report, available only if the optional external
printer is installed.
performance:
Instruct subject about the protocol and adjust
•
the chest belt for reliable pulse.
Select YCMA protocol.
•
Setup subject age, maximum heart rate, weight
•
and sex according to menu.
Protocol operation may be terminated by de-
•
pressing START/STOP (3).
The protocol will terminate automatically under
two circumstances;
1) nine minutes (3 levels) have been
completed, or
2)six minutes (2 levels) have been
completed and the heart rate elicited by
the first level was 110 bpm or more.
In addition, START/STOP may be used to end
protocol operation after six minutes if the subject
is having difficulty.
Note: Stated HR values are at the end of each level.
