Reviewing results
The maximum oxygen uptake is the standard
measurement of cardiopulmonary fitness. Dependent
on the linear relationship between work and oxygen
uptake and between work and heart rate, the heart
rate response to work may be used to estimate the
oxygen consumption. If the maximum heart rate is
considered, the maximum oxygen consumption may
be determined.
The YMCA and Åstrand protocols estimate
the maximum oxygen consumption, based on a
submaximal workload while all others report the
oxygen consumption required by the final workload.
The Bruce and Naughton protocols require that the
test subject exercise at a workload level for a minimum
of one minute to establish the oxygen consumption.
If less than one minute is observed, the previous
workload value is used.
The estimated maximum oxygen consumption
derived from some of the ergometer tests is subject
to the error of the “age related predicted maximum
heart rate“. Although there is a definite and linear
relationship between work and oxygen uptake, there
are some differences in actual oxygen uptake based on
individual work efficiency. Test subjects who are less
familiar with bicycle exercise and those individuals
who are less fit, are more likely be less efficient than
those who ride bicycles frequently.
It should be noted that these results are estimates or
predictions of maximal response and have a greater
chance of being in error than if the individual were
tested to their actual maximum value. Interpretation
should therefore be made more carefully with an
understanding of the possibility of errors in the
methodology.
