Section #4 Flashcards
Which screening tool is used to evaluate the benefits and risks associated with starting any type of exercise that is strenuous in nature?
Health Risk Assessment (HRA)
Which of the following health indicators is reflected in the PAR-Q+ and preparticipation process?
Desired Exercise Intensity
Fitness assessments that do not require physical exertion (such as the measurement of RHR, blood pressure, or body composition) should always be conducted after more vigorous fitness assessments (such as those that measure aerobic fitness, strength, or power output).
False
What term is used to describe the physiological process by which the body maintains a relatively constant internal temperature?
Thermoregulation
Why does NASM recommend fitness professionals measure resting heart rate (RHR) at the radial pulse versus the carotid pulse?
The vagus nerve lies adjacent to the carotid artery, and pressure on this nerve can slow a client’s heart rate response.
What is the field of study of the measurement of living humans for purposes of understanding human physical variation in size, weight, and proportion?
Anthropometry
Which of the following represents the measurement of a person’s weight relative to their height?
BMI (Body Mass Index)
Which principle assumes that the volume of fluid displaced by an object is equivalent to the volume of the object fully immersed in that fluid or to the specific fraction of the volume below the surface?
Archimedes’ Principle
What is the most valid measurement of aerobic fitness?
VO2max
Which of the following is the part of the cell that uses nutrients to create energy for the cell?
Mitochondrion
From the list of assessments provided, which should be conducted first to preserve its validity?
Body Composition
What is Bernadette’s waist-to-hip ratio (WHR) if she is measured with a waist circumference of 28 inches and a hip circumference of 33 inches?
.85 (Waist/Hip)
What is the definition of anthropometry?
The field of study of the measurement of living humans for purposes of understanding human physical variation in size, weight, and proportion
What step height is used for the YMCA 3-minute step test?
12 inches
Which of the following is a recommendation when assessing skinfold measurements?
Take a minimum of two measurements at each site; each measurement must be within 1 to 2 mm to take an average at each site.
Which skinfold sites are measured if determining body composition via the Durnin-Womersley protocol?
Triceps, Biceps, Subscapular, Suprailiac
Which test provides the most personalized assessment of an individual’s true metabolic function?
Ventilatory Threshold (VT1) Test
What is best defined as the action of expanding the diameter of a blood vessel near the surface of the skin, which helps remove heat from the body?
Peripheral Vasodilation
Which test would you select as the most appropriate when attempting to measure the overall fitness level of a fit college-aged athlete who competes on the school’s rugby team?
The 1.5 Mile Run Test
Which of the following represents a criterion for terminating an exercise test or exercise bout that involves exertion?
Any indication of chest pain or angina-like symptoms
In which BMI category would you classify Vincent if he has a BMI of 27?
Overweight (25 - 29)
What principle is hydrostatic underwater weighing based upon?
Archimedes’ Principle
What term refers to the ability of a test to produce consistent and repeatable results?
Reliability
How can diastolic blood pressure be defined?
The pressure in arteries and other blood vessels when the heart is at rest or between beats; the second (bottom) number recorded
When sequencing physiological assessments, which of the following would produce a better result if measured immediately after exercise rather than before exercise?
Flexibility
Which term defines the degree to which a test specifically measures what it is intended to measure?
Validity
What would not be a reason to terminate an exercise test?
Individual is tired from the test.
In most individuals, to what pressure is the blood pressure cuff inflated when measuring resting blood pressure?
The cuff is inflated to a value of 20 to 30 mm Hg above the point at which the pulse can no longer be felt at the wrist.
From the list of assessments provided, which should be conducted first to preserve its validity?
Body Composition
Where is it most common to take an individual’s circumference measurement to assess health risk?
Waist
What artery is used to measure blood pressure?
Brachial Artery
What term refers to the ability of a test to produce consistent and repeatable results?
Reliability
Which of the following intensities best represents VT2 during the incremental test protocol?
When the individual responds with “no” when asked, “Can you speak competently?”
What is the best description of a steady-state heart rate?
Any stage at which the physiological response of heart rate from the cardiovascular system becomes relatively constant in relation to the amount of work being performed
In which BMI category would you classify Mary if she has a BMI of 17.5?
Underweight
How many skinfold sites are measured when determining body composition using the Durnin-Womersley protocol?
4
Into which category would a resting blood pressure score of 128/79 mm Hg fall?
Elevated
What population is the VT2 talk test appropriate for?
Individuals with performance goals
Which of the following tests uses recovery heart rate rather than exercising heart rate to evaluate cardiorespiratory fitness levels?
YMCA 3-minute step test
Which term refers to a state where muscles on each side of a joint have altered length-tension relationships?
Muscle Imbalance
