Section 4 Definitions Flashcards
mortality
a state or a risk of death or dying
morbidity
the state of having a disease
high-intensity interval training (HIIT)
an exercise training method defined bu intervals of near-maximal intensity broken up by relatively short rest periods
deconditioned
a sate of lost physical fitness, which may include muscle imbalances, decreased flexibility, and a lack of core and joint stability
health risk assessment (HRA)
a screening tool used to evaluate the benefits and the risks associated with starting any type of exercise that is strenuous in nature
contraindication
a specific situation where a medication, procedure, or exercise should be avoided because it may prove to be harmful to the individual
physical activity readiness questionnaire (PAR-Q+)
a detailed questionnaire designed to assess an individual’s readiness to engage with structured exercise
false-positive screenings
a screening where the result of the health risk assessment might indicate a need for medical clearance, when one is in fact not needed
health history questionnaire (HHQ)
a questionnaire with lists of questions that pertain to the health history and habits of a potential client, such as exercise history, eating behaviours and general lifestyle
resting heart rate (RHR)
bpm while at complete rest
thermoregulation
a physiological process by which the body maintains a relatively constant internal body temperature, including events like sweating to cool, and shivering to warm the body
peripheral vasodilation
action of expanding the diameter of a blood vessel near the surface of the skin, which helps to remove heat from the body
heart rate (HR)
measurement of number of times heartbeats in a specified period of time, usually 1minute
blood pressure (BP)
outward pressure exerted by the blood on the vessel walls: systolic/diastolic
systolic blood pressure (SBP)
the pressure in the arteries and other vessels when the heart is contracting, the first/top number
diastolic blood pressure (DBP)
the pressure in the arteries and other vessels between beats, when the heart is at rest, the second/bottom number
arterial system
system of arteries carrying blood away from the heart
brachial artery
primary artery of upper arm, often used as a site of measuring blood pressure
anthropometry
field of study of the measurement of living humans for the purpose of understanding human physical variation in size, weight, and proportion
BMI
a person’s weight relative to height, used to estimate risk of obesity
circumference measurement
measurement that determines overall dimensions (girth) of a body segment, estimate body composition, or prevalence of obesity
waist circumference
narrowest circumference taken around the midline of the body at the approximate height of belly button
waist-to-hip ratio (WHR)
relative score expressing the ratio of the waist circumference to the hip circumference, correlates to the risk for developing cardiovascular disease
gluteal fold
the area where the fold of the buttocks joins the back of the thigh
skinfold measurements
a technique used to estimate body fat in which calipers are used to pinch the skin in certain areas of the body
Jackson and Pollock 7-site protocol
measures the thickness of skinfolds at 7 sites on the body to estimate body fat percentage. chest, mid-axillary, subscapular, triceps, abdoment, suprailiac, thigh
Jackson and Pollock 3-site protocol
M: chest, abdomen, thigh
F: triceps, suprailiac, thigh
4-site Durnin-Womersley protocol
biceps, triceps, subscapular, suprailiac
bioelectrical impedance analysis (BIA)
a body composition assessment tool that estimates body fat percentage by measuring the resistance to the flow of electrical currents introduced into the body
