heart rate response to the warmup. The test is designed to raise the steady-
state heart rate of the subject to
115
to
150
beats/min for two consecutive
stages. It is important to remember that two consecutive heart rate measure-
ments must be obtained in the
115
to
150
beats/min range to predict V0
2max
'
The test typically lasts from 9 to 15 minutes.

In the StairMaster protocol. each work rate is performed for 3
minutes, with heart rates recorded during the final 4 seconds of the 2
nd
and Jrd
minutes of each stage. If the heart rates are within 5 beats/min. then the heart
rate during the last minute is plotted against the work rate. and the program
advances to the next 3-minute stage. The program continues for 2 to 4 stages
until 2 steady state heart rates between 115 to 150 beats/min are obtained in 2
consecutive stages. The line generated from the plotted points is then extended
to the age-predicted maximal heart rate. A corresponding maximal work rate and
VOzmaJ. can then be calculated.
At the end of the 3
rd
minute of each stage. if the heart rates at the end
of the 2 nd and Jrd minute are not within 5 beats/min of each other, then that work
rate is maintained for an additional minute. At the end of the 4
th
minute, the
heart rate is compared to the heart rate at the end of the 3 rd minute. If the heart
rates are within 5 beats/min, then the heart rate during the 4
th
minute is plotted
against the work rate. If the heart rate at the end of the Jrd and 4 th
minute are
not within 5 beats/min. then the work rate is maintained for one more additional
minute. If the heart rate at the end of the 4
th
and 5
th
minutes are within 5 beats/
min. then the heart rate at the end of the 5
th
minute is plotted against the work
rate. If the heart rate at the end of the 4 th and 5 th minutes are not within 5 beats/
min, then the test failed.
Once 2 consecutive heart rate measurements are obtained in the
115
to 150 beats/min range, then the test ends successfully and the results are
displayed. The estimated maximum aerobic capacity is shown in ml/kg/min and
METs. Next. the results are compared to normative values for others of the same
age range and gender (see Table 2). Results are stored in the console until the
next person starts an exercise program.
