Exs Phys Lab Health Screens and Informed Consent plus Conversions

Informed consent

explains the purpose, risks, and benefits of participating in the testing process; allows parental approval (as appropriate)

PAR-Q+

helps determine the individual’s readiness to perform physical activity; 7 questions; a single “yes” means that medical clearance is required

What does PAR-Q stand for

Physical Activity Readiness Questionnaire

Medical and health history

collects information about the individual’s past and present personal health history and family history; the focus is on conditions that require medical referrals and clearance

Signs and symptoms of disease and medical clearance

Identifies individuals who need physician’s approval, via a medical referral, to perform exercise testing

Coronary risk factor analysis

establishes risk by quantifying the individual’s number of coronary heart disease risk factors

Lifestyle evaluation

gives insight into the individual’s living habits

Disease risk classification

categorizes the individual as high, medium, or low risk

Low risk

asymptomatic and young and <2 net risk factors for CVD

Moderate risk

asymptomatic and >1 net risk factor for CVD; applies to both younger and older groups

High risk

symptomatic or known cardiovascular, pulmonary, or metabolic disease

English or standard units

originally based on anatomical measures (current king’s foot), later standardized but no common base

Mass

kilogram

Distance

meter

Force

newton (N), however, we use kg

Work

joule (J), however we use kg-m

Energy

joules (J), however we tend to think in calories

Time

seconds

Power

watts (W) which we usually derive from kg-m/min

Velocity

m/s however we use m/min or Km/h

Work equation

force x distance (FxD)

Power equation

work per unit of time (W/t)

Relative equation example

156.9 W / 74 kg (power relative to someone who weighs 74 kg)
