Clinical Exercise Testing and Interpretation (Quiz)

  1. Please describe the difference between clinical exercise testing and health-related exercise testing

    1. Clinical exercise testing is primarily focused on diagnosing and evaluating cardiovascular and pulmonary conditions through controlled exercise protocols, while health-related exercise testing assesses an individual's fitness level and overall health status to provide guidance for exercise prescription and health promotion.

  1. Indications for clinical exercise testing encompass which 3 categories

    1. Diagnosis, prognosis, evaluation of physiologic response

  1. Describe the term contraindication

    1. Contraindication refers to a specific situation or condition in which a particular treatment or procedure, such as exercise testing, should not be performed due to the potential for harm or adverse effects to the patient.

  1. Select all of the following that are considered absolute contraindications to maximal exercise testing

    1. Acute myocardial infarction, active endocarditis, decompensated heart failure, physical disability that precludes safe and adequate testing

  1. Please list 2 reasons you might terminate a maximal exercise test in the middle of testing.

    1. The individual requests to stop the testing. This could be due to muscle cramps, chest pains, feeling light-headed, etc.

    2. While monitoring blood pressure throughout the test, if there is a decrease in SBP by more than 10 mmHg, the test should be stopped.

  1. To conclude that maximal effort has be elicited during a GXT, a peak RER:

    1. Greater than 1.1

  1. To conclude that maximal effort has be elicited during a GXT, HR:

    1. Fails to increase with increase in workload

  1. Describe the difference between the terms maximal and peak in relation to clinical GXT. Discuss why making this distinction is important.

    1. Maximal in relations to clinical GXT refers to the highest level of exertion that the tested individual can sustain. To determine this, the physician can look for a plateau in VO2 with increased workload, an RPE greater than 17, and/or a peak RER greater than or equal to 1.10.

    2. Peak in relations to clinical GXT refers to the the highest absolute value achieved during the test.

    3. It is important to understand the distinction because a maximal response can show the individual’s physiological capacity of their cardiovascular & respiratory systems. On the other hand, a peak response may misinform the physician about the individual’s true fitness level or health status.
