-Maximal effort tests must be used to directly measure V02MAX, however,
V02MAX
can be estimated with submaximal tests. The decision to perform a
submaximal or maximal test depends upon subject type, available equipment and
personnel, and the purpose of the test. The basic aim of submaximal testing is to
determine the relationship between a subject's heart rate response and his/her
V02
during progressive exercise and use that relationship to predict V02MAX. Often,
heart rate and
V02
are measured
in
two or more separate submaximal tests and
plotted
on
a graph to better show their linear relationship
in
a given individual.
Submaximal tests are frequently used
in
assessing the presence of cardiovascular
diseases, classifying cardiorespiratory fitness level, or prescribing an aerobic
exercise program.

GOAL: To obtain complete as much of the Bruce protocol to
est1mate
V02 max.
RECORD: HR at end of each stage,
PROTOCOL:
-Warm up for 10 min

-Begin the Bruce protocol at the first stage,
-Monitor HR at the last 15 seconds of each stage
-Complete the protocol until the subject cannot safely continue
-Record time as a total number. Example 9 min 15 sec = 9.25
