other physical reason against your exercising without medical supervision?
Sub-maximal Fit Test
The Fit Test is a program that estimates maximal aerobic capacity based on HR
response to sub-maximal exercise.
The branching protocol is a series of 3-minute stages of continuous
exercise at increasing intensity. The rst stage is a warm-up at approximately
4 METs. The intensity of the remaining stages is based on the HR response to
the warm-up. The test is designed to raise the steady state HR of the subject
to at least 115 BPM. It is important to remember that two consecutive HR
measurements must be obtained above 115 BPM to predict VO
typically lasts from 6 to 15 minutes. The test will terminate if the HR does not
continue to rise from state to stage.
In the protocol, each work rate is performed for 3 minutes, with HR's
recorded during the nal 4 seconds of the second and third minutes of each
stage. If the HR's are within 5 BPM, then the HR 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 HR's above 115
BPM are obtained in two consecutive stages. The line generated from the plotted
points is then extended to the age-predicted maximal HR. A corresponding
maximal work rate and VO
At the end of the 3rd minute of each stage, if the HR's at the end of the 2nd and
3rd minute are not within 5 BPM of each other, then that work rate is maintained
for an additional minute. At the end of the 4th minute, the HR is compared to the
HR at the end of the 3rd minute. If the HR's are within 5 BPM, then the HR during
the 4th minute is plotted against the work rate. If the HR at the end of the 3rd and
4th minute are not within 5 BPM, then the work rate is maintained for one more
additional minute. If the HR at the end of the 4th and 5th minutes are within 5
BPM, then the HR at the end of the 5th minute is plotted against the work rate. If
the HR at the end of the 4th and 5th minutes are not within 5 BPM, then the test
failed.
