Peripheral vasodilation
The standard Jackson and Pollock 3-Site protocol for women requires skinfold measurements at which of the following sites?
Suprailiac, thigh, and triceps
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
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.
Which of the following is the initial assessment that should be completed prior to starting any exercise or training program?
Health risk assessment
What would not be a reason to terminate an exercise test?

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?
0.85
What interventions are suggested for an individual with a resting blood pressure of 134/86 mm Hg?
Some lifestyle changes coupled with some medical monitoring
The PAR-Q+ and preparticipation process reflects what three health indicators?

What does BMI (body mass index) assess for?
Whether a person’s weight is appropriate for their height
Which of the following statements defines the chest skinfold location for men?
A diagonal fold taken half the distance between the anterior axillary line and the nipple
What is the most valid measurement of aerobic fitness?
VO2max
What is the physiological process by which the body maintains a relatively constant internal body temperature, including events like sweating to cool the body and shivering to warm the body?
Thermoregulation
When sequencing physiological assessments, which of the following would produce a better result if measured immediately after exercise rather than before exercise?
