CHPT 11 Flashcards
Contraindication
A specific situation where a medication, procedure, or exercise should be avoided because it may prove to be harmful to the individual
it is necessary to always screen an individual with an _____ prior to starting any exercise regimen that involves exertion
HRA
Physical Activity Readiness Questionnaire (PAR-Q+)
It is a questionnaire given to prospective clients to gain insight into their current health and wellness.
PAR-Q+ reflects these health indicators:
current physical activity
signs or symptoms or known disease
desired exercise intensity
Part one of the PAR Q has
7 questions
An HHQ typically contains the following information about a client
Age
Gender
Height
Weight
Physician’s name and contact information
Emergency contact information
Thermoregulation
The physiological process by the body maintains a constant internal body temperature
Peripheral vasodilation
The action of expanding the diameter of a blood vessel near the surface of the skin, which helps remove heat from the body
Arterial system
The system of arteries carrying blood away from the heart.
Brachial artery
The primary artery of the upper arm, which is often used as a site for measuring blood pressure
BMI calulation
703 × weight (lb) ÷ [height (in.)]2
BMI healthy
18.5–24.9
Jackson and pollock seven site protocol: men & women
Chest, mid-axillary, subscapular, triceps, abdomen, suprailiac, thigh
Four-Site Durnin–Womersley protocol: men &
women
Biceps, triceps, subscapular, and suprailiac
Jackson and Pollock Three-Site Measurement: men
Chest, abdomen, thigh
Jackson and Pollock Three-Site Measurement: women
Triceps, suprailiac, thigh
Bioelectrical impedance analysis (BIA)
A body composition assessment technique that estimates body fat percentage by measuring the resistance to the flow of electrical currents introduced into the body.
Archimedes’ principle
the assumption stating that the volume of fluid displaced is equivalent to the volume of an object fully immersed in that fluid or to the specific fraction of the volume below the surface.
Anthropometry
the field of study of the measurement of living humans for purposes of understanding human physical variation in size, weight, and proportion
The ability of the circulatory and respiratory systems to provide the body with oxygen during activity
Cardiorespiratory fitness
Protocols intended to measure the aerobic fitness of an individual
Cardiorespiratory assessments
a measure of body’s usage rate of oxygen; it’s the difference between inspired and expired oxygen
Oxygen consumption (VO2)
usually peaks at around ages 25 years to the early 30s
VO2max
a technique used to express or validate how hard a client feels that they are working during exercise
rating of perceived exertion (RPE)
a cardiorespiratory assessment that assesses the aerobic fitness of deconditioned clients by having them complete 3 minutes of continuous stepping on and off a 12-in. (30-cm) box
YMCA 3-minute step test
considered suitable for low-risk, apparently healthy, nonathletic adults
YMCA 3-minute step test
a 1-mile walking test that predicts maximal oxygen consumption (VO2max) from either a timed performance or heart rate response
Rockport walk test
an informal cardiorespiratory assessment used to gauge the intensity of the activity based on the client’s own unique metabolic markers and ability to hold a conversation
talk test
an incremental test performed on any device (e.g., treadmill, bicycle) that gradually progresses in intensity level and relies on the interpretation of the way a person talks to determine a specific event at which the body’s metabolism undergoes a significant change
ventilatory threshold 1 (VT1)
flexibility is frequently assessed following
a light cardio warm-up because at this time the body displays greater tissue extensibility
Thermoregulation during exercise creates
peripheral vasodilation at or around the skin to help remove heat, but this can increase a skinfold body fat measurement score
