7.3.3 RAMP protocol
The ramp protocol is very similar to the incre-
mental protocol in that it is based on a continu-
ously increasing series of workloads. The major
difference is that the ramp protocol steps are ex-
tremely fine, making the tension from one wor-
kload step to the next nearly imperceptible.
Ramp protocol are sometimes employed to pro-
vide a very rapid rise in workload in an attempt
to determine the maximum workload which a
subject can achieve without significant elevation
in blood lactic acid from anaerobic metabolism.
Due to the rapid rise in workload, there is little
fatigue, although the medical risk may be high
if an extremely high workload is attained too
quickly.
Similar to the incremental, the ramp protocol
must be programmed prior to running. The pro-
gramming is slightly different in that the worklo-
ad increase per minute is entered rather than the
step time and step work increments.
Operation is similar as well, except that the pro-
tocol may not be advanced or retarded.
Instruct subject about the protocol and adjust the
chest belt for reliable pulse.
Follow menu instructions and start test.
7.3.2 INCREMENTAL protocol
The incremental protocol consists of a series of
workloads which are constantly increasing with
time. Under control of the incremental, the ergo-
meter exercises the subject to a maximum wor-
kload. The rate at which the workload rises can
be preset.
The type of work: power or force may also be
preset as desired. The incremental protocol may
be used to create a linearly increasing workload
test such as a modification of Naughton protocol.
The Naughton may be viewed as an incremental
protocol with a work type of V02 and a rate of
3.5 ml/kg/min every two minutes.
Set the subjects age, maximum heart rate, sex
weight and selects the protocol.
Type of workload must be programmed. This sto-
res the time and workload rate of change in con-
tinuous memory. Each step is calculated from the
previous step plus the step time and step work,
constantly increasing.
During executions of the protocol, the IN-
CREASE and DECREASE keys (key 9 or 6) may
be used to advance or retard the protocol. In this
manner, if a workload is too easy, the protocol
may be advanced in a non-linear fashion until the
workload is as desired.
Instruct subject about the protocol and adjust the
chest belt for reliable pulse.
Follow menu instructions and start test.
