Nautilus Sub-Maximal Fit Test - Nautilus TREADCLIMBER TC916 Owner's Manual

nautilus sub-maximal Fit test
®
The Nautilus ® Fit Test is a program that estimates maximal aerobic capacity based
on heart-rate response to sub-maximal exercise.
The Nautilus ® branching protocol is a series of 3-minute stages of continuous
exercise at increasing intensity. The first stage is a warm-up at approximately 4
METs. The intensity of the remaining stages is based on the heart rate response to
the warm-up. The test is designed to raise the steady state heart rate of the subject
to at least 115 beats per minute. It is important to remember that two consecutive
heart rate measurements must be obtained above 115 beats per minute to predict
VO . The test typically lasts from 6 to 15 minutes. The test will terminate if the
2max
heart rate does not continue to rise from state-to-stage.
®
In the Nautilus protocol, each work rate is performed for 3 minutes, with heart
rates recorded during the final 4 seconds of the second and third minutes of each
stage. If the heart rates are within 5 beats per minute, 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 two-to-four stages until two steady state
heart rates above 115 beats per minute are obtained in two 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 VO
calculated.
At the end of the third minute of each stage, if the heart rates at the end of the
second and third minute are not within 5 beats per minute of each other, then that
work rate is maintained for an additional minute. At the end of the fourth minute,
the heart rate is compared to the heart rate at the end of the third minute. If the
heart rates are within 5 beats per minute, then the heart rate during the fourth
minute is plotted against the work rate. If the heart rate at the end of the third and
fourth minute are not within 5 beats per minute, then the work rate is maintained
for one more additional minute. If the heart rate at the end of the fourth and fifth
minutes are within 5 beats per minute, then the heart ate at the end of the fifth
minute is plotted against the work rate. If the heart rate at the end of the fourth and
fifth minutes are not within 5 beats per minute, then the test failed.
Once two consecutive heart rate measurements are obtained above 115 beats
per minute range, then the test ends successfully and the results are displayed.
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.
