What is a cardio respiratory fitness test? - (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? - (answer)True
High CRF indicate high levels of habitual physical activity which are associated with health benefits
What is VO2max? - (answer)VO2max or Maximal oxygen uptake is a way to measure cardiorespiratory
fitness.
How is VO2max relatively expressed? - (answer)(mL/kg/min)
How is VO2max absolutely expressed? - (answer)(mL/min)
What does VO2max relatively expressed compares? - (answer)Relatively expressed VO2max compares
between individuals with differing body weight
What is VO2max the product of? - (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. - (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?
,ACSM Health Fitness Specialis
(VO2 on the y-axis and work rates on the x-axis.) - (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? -
(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 - (answer)-Open circuit spirometry
-Indirect measures: Submaximal test
-Maximal test
How to measure VO2max using open circuit spirometry - (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: - (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. - (answer)-Reason for the test
-Risk level of client/ patient
-Availbility of appropriate equipment and personnel
True or False
, ACSM Health Fitness Specialis
Maximal testing allows for accurate assessment of anaerobic/ventilators threshold and direct
measurement of VO2 max/VO2 peak. - (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? -
(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? - (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? - (answer)-HR
-BP
-Workload
-RPE
Modes for exercise testing - (answer)-Treadmill
-Cycle ergometer
-Steps and field tests
