Chapter 2 Flashcards
What is the purpose of pre-assessment screening?
to identify people who have medical contradindications to specific health-related physical fitness assessments, should receive medical clearance prior to assessment, and should participate in medically-supervised exercise
What is an informed consent form?
documentation of clear communication between the assessor and assessee
What are the essential components of an informed consent form?
to explain the purpose of the assessments, describe the upcoming procedures, responsibilities of the client, and explain how data will be handled and use of private medical information.
What is the purpose of the health history questionnaire?
to gather the client’s demographic and health-related information to determine potential risks prior to participation in exercise testing
What does the health history questionnaire entail?
family history, personal history of disease/illness, surgical history, past/present health behaviors, and current use of drugs and medications
What are the current guidelines for contraindications to exercise?
previously inactive men over age 40, women over age 50, and people at high risk for CVD should first consult a physician
What is the difference between a PAR-Q and HHQ?
PAR-Q is simpler and still screens for those at highest risk for sudden death or those with medical contraindications
What is the purpose of a risk stratification?
it identifies the appropriate course of action for assessment and exercise prescription
What are the 3 classes (strata) for risk stratification?
low, moderate, and high risk
What does the risk stratification answer?
2 questions: should this person have a medical examination before physical activity? is it recommended that a physician is present during physical activity?
Definition of low risk
less than two risk factors
Definition of moderate risk
Asymptomatic but have 2 or more of the risk factors
Definition of high risk
individuals who have any signs or symptoms or have a known cardiovascular, pulmonary, or renal disease or diabetes
What are ways to minimize measurement error?
provide pre-test instructions, be well-organized, use good quality (well-calibrated) instruments, pay attention to details, and perform multiple trials
What are some post-test procedures?
shower with lukewarm water, avoid heavy meals and smoking, avoid strenuous exercise, double check how client is feeling, ask if there are any questions
What are quiet tests?
resting heart rate, blood pressure, and body composition
What is blood pressure?
the force of blood against walls of the vasculature created by contraction of the heart
Where is blood pressure typically measured?
usually within the muscular arteries
How is blood pressure assessed?
By indirect auscultation (listening to the sounds)
is blood pressure fixed or dynamic?
dynamic
Blood pressure =
cardiac output times total peripheral resistance (vasodilation, vasoconstriction)
What is systolic blood pressure?
maximum pressure during ventricular contraction, reflects the work of the heart, and important indicator of cardiovascular function during exercise
What is diastolic blood pressure?
The minimum pressure during cardiac relaxation and reflects peripheral resistance in arterial blood vessels
What is hypotension?
abnormally low blood pressure (less than 90/60) and results in inefficient pooling of blood, and fatigue
