31

where is the gender-specific essential fat located/involved?

- mammary glands
- pelvic region
- involved in hormone-related functions and pregnancy

32

what are the 2 ways of measuring body fat?

1) direct measurement
2) indirect measurement

33

______ measurement of body fat involves grinding tissue

direct measurement

34

which way of measuring body fat measures fat via chemical analysis

direct measurement

35

true or false: direct measurement of body fat is impractical for living organisms

true

36

direct measurement is used with _____

cadavers

37

list 5 methods of indirect measurement of body fat

1) skin fold callipers
2) hydrostatic weighing
3) bod pod
4) bioelectrical impedance
5) DEXA

38

skin fold callipers

measure skin fold thickness to predict or estimate total body fat

39

what is skin fold calliper testing based on?

based on the assumption that subcutaneous fat is directly related to total body fat

40

what is the accuracy of skin fold calliper testing?

accuracy is +-3 when performed correctly

41

hydrostatic weighing

determines body density to be used in further equations that calculate percent body fat

42

what is hydrostatic based on?

based on archimedes' principle of water displacement - an object submerged in water yields a buoyant force equal to the weight of water displaced

43

to calculate body fat with hydrostatic weighing, what 4 measurements are needed?

1) body weight on land
2) underwater body weight
3) water density at the performed temperature
4) residual lung volume

44

what is a more accurate measure: hydrostatic weighing or skin fold callipers?

hydrostatic weighing is more accurate

45

what is a very accurate measure or body fat, but also comes with a high expense?

the bod pod

46

what can the bod pod do that hydrostatic weighing can not?

may facilitate measuring large or heavy individuals because it does not involve underwater submersion

47

what does the bod pod use to calculate body fat percentage?

air displacement

48

what is bioelectrical impedance based on?

based on differences in electrical conductivity between fat-free mass and fat mass

49

how is percent body fat calculated in BIA?

percent body fat is calculated from measures of body density determined by passing an electrical current through the body

50

what is BIA influenced by?

the subjects hydration level

51

true or false: the more hydrated someone is, the heavier the BIA measurement will be

FALSE: the more hydrated someone is, the leaner the BIA measurement will be

52

DEXA can be used to determine ___________ and can also measure bone density (bone mineral content)

body composition

53

what is an easy, inexpensive method for determining an individuals healthy body weight?

BMI (Body mass index)

54

how is BMI calculated?

BMI = Weight (Kg)/[Height (m)]2

55

what are the 3 general ranges of BMI?

1) underweight
2) healthy or acceptable weight
3) overweight (severe overweight or morbid obesity)

56

a BMI score above ___ is classified as obese and associated with an increased risk of developing health problems

30

57

true or false: health problems are associated with BMI's classified as being within the underweight range

true

58

who is the BMI intended for?

men and women aged 20-65

59

who is BMI strictly not intended for? (list 5)

1) babies
2) children
3) teenagers
4) pregnant women
5) very muscular people, such as athletes

60

somatotyping - the human body is composed of what 3 things?

1) roundness
2) muscularity
3) linearity
