Chapter 11: Lesson 4 Flashcards
Body mass index (BMI)
The measurement of a person’s weight relative to his or her height, which is used to estimate the risks of obesity.
Anthropometry
The field of study of the measurement of living humans for purposes of understanding human physical variation in size, weight, and proportion.
Circumference measurement
The measurement that determines the overall dimension (girth) of a body segment, which can be used to estimate body composition or the prevalence of obesity.
Gluteal fold
The area where the fold of the buttocks joins the back of the thigh.
Waist circumference
A measurement that represents the narrowest circumference taken around the midline of the body at the approximate height of the umbilicus (belly button).
Waist-to-hip ratio (WHR)
The relative score expressing the ratio of the waist circumference to the hip circumference, which correlates to the risk for developing cardiovascular disease.
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 seven different places within the body to estimate body fat percentage.
Jackson and Pollock 3-Site protocol
Measures the thickness of skinfolds at three different places within the body to estimate body fat percentage.
Four-site Durnin– Womersley protocol
Measures the thickness of skinfolds at four different places (biceps, triceps, subscapular, and suprailiac) within the body to estimate body fat percentage.
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.
