VO2 Test
The VO2 program is based on the YMCA protocol and is a
sub-maximal test that uses pre-determined, fixed work levels that
are determined based on the heart rate readings measured as the
test progresses. The test will take anywhere between 6 to 15 minutes
to complete, depending on the fitness level of the user. The test ends
when the user’s heart rate reaches 85% of maximum at any time
during the test, or the heart rate is between 110 bpm and 85% at the
end of two consecutive stages. At the end of the test a VO2max score
will be displayed. VO2 stands for Volume of Oxygen uptake which is a
measurement of how much oxygen you need to perform a known
amount of work. The YMCA protocol employs two to four stages,
lasting 3 minutes each, of continuous exercise (see charts below). You
will be prompted to choose either, Male or Female at the beginning
of the test. This choice determines which protocol will be used during
the test as shown in the charts below. The only caveat is if you are a
very de-conditioned male you may need to choose option Female. If
you are a very conditioned female you may need to choose option
Male.
