What is a cardio respiratory fitness test? ✔Correct Answer-Ability to perform large muscles,
dynamic, moderate to vigorous intensity exercise for prolonged periods of time.
Low CRF is associated with increased risk of premature death from all causes including CVD.
True or False? ✔Correct Answer-True
High CRF indicate high levels of habitual physical activity which are associated with health benefits
What is VO2max? ✔Correct Answer-VO2max or Maximal oxygen uptake is a way to measure
cardiorespiratory fitness.
How is VO2max relatively expressed? ✔Correct Answer-(mL/kg/min)
How is VO2max absolutely expressed? ✔Correct Answer-(mL/min)
What does VO2max relatively expressed compares? ✔Correct Answer-Relatively expressed
VO2max compares between individuals with differing body weight
What is VO2max the product of? ✔Correct Answer-Maximal Cardiac Output (Q) (L blood/min) and
arterial venous O2 difference (mLO2/L blood)
True or False
VO2 max is closely related to the functional capacity of the heart and skeletal muscles. ✔Correct
Answer-False
VO2 max is closely related to the functional capacity of the heart.
How do you know someone has reached their VO2 max if you are looking at a graph?
(VO2 on the y-axis and work rates on the x-axis.) ✔Correct Answer-VO2max implies an individuals
true physiological limit has been reached and a plateau in VO2 may be observed between the final
two work rates of a progressive exercise test.
Would you observe the VO2 max plateau for individuals with CVD or pulmonary disease? ✔Correct
Answer-Plateau is rarely observed in individuals with CVD or pulmonary disease. Instead, peak
plateau is observed for CVD or pulmonary diseases
Ways to measure VO2 max ✔Correct Answer--Open circuit spirometry
-Indirect measures: Submaximal test
-Maximal test
, How to measure VO2max using open circuit spirometry ✔Correct Answer--Subject breathe
through a low resistance valve with their nose occluded
-Pulmonary ventilation, expired fraction of O2 and carbon dioxide are measured
-Calibraion of system is essential for accurate use
Overestimation of a submaximal test can occur if: ✔Correct Answer--Exercise protocol chosen for
testing is too aggressive for a given individual. (ex. Bruce protocol with patients who have congestive
heart failure)
-Treadmill test given, but individual rely on hand rail support
What things should an exercise physiologist consider when deciding to administer a maximal or
submaximal test. ✔Correct Answer--Reason for the test
-Risk level of client/ patient
-Availbility of appropriate equipment and personnel
True or False
Maximal testing allows for accurate assessment of anaerobic/ventilators threshold and direct
measurement of VO2 max/VO2 peak. ✔Correct Answer-True.
Maximal test require participant to exercise to the point of volitional fatigue.
As a reminder medical supervision is needed for high risk individuals, recommended for moderate
risk and its not needed for low risk.
In the health/fitness setting which is more likely to be administered. A maximal or submaximal test?
✔Correct Answer-Submaximal testing is more commonly used to assess cardiorespiratory fitness
because maximal exercise test is not always feasible in the health/fitness setting.
-Submax is also recommended in stable patients
What is the goal of a Submaximal test? ✔Correct Answer-Submax test aims to determine the HR
response to one or more Submax work rate and use the result to predict VO2 max
What does a typical submax test measure? ✔Correct Answer--HR
-BP
-Workload
-RPE
Modes for exercise testing ✔Correct Answer--Treadmill
-Cycle ergometer
-Steps and field tests
True or False
Most accurate estimate of VO2max is achieved from BP response to increasing work rate during the
submaximal test. ✔Correct Answer-False
Most accurate estimate of VO2max is achieved from HR response to submaximal exercise test.
