Q

hydrodensitometry uses underwater weighing method from air volume displaced by the body when fully submerged

A

false (water)

25
Q

body fat is calculated from body density using densitometry method- 2 component model to assess body composition

A

true

26
Q

the archimedes principle describes that the buoyant force is equal to the weight of the displaced water

A

true

27
Q

to evaluate _____ of the test, you will have to have another person measure the same client

A

objectivity

28
Q

air displacement (bod pod) follows poisson’s law because of the isothermal condition that the chamber creates

A

false

29
Q

body density from our hydrostatic weighing lab is calculated by the body weight measured in the air minus the body weight measured in the water divided by the density of water

A

false ( this principle calculates body volume)

30
Q

_____ describes the amount of air trapped in lungs after a maximal expiration

A

residual volume

31
Q

the assumed amount of gas trapped in the gastrointestinal system when you use hydrostatic weighing method to assess body composition is approximately

A

0.1L

32
Q

It is assumed that proportions of components in fat free mass varies from person to person when using densitometry

A

false (relatively consistent from person to person)

33
Q

adiabatic conditions describe when the temperature of air does not remain constant as the volume changes

A

true

34
Q

using Bod Pod, body volume can be overestimated if there is a greater body surface area from lots of hair

A

false (?)

35
Q

when using bod pod height and weight are necessary to calculate body surface area

A

true

36
Q

using bod pod estimated % body fat is calculated based on the siri equation and two component model

A

true

37
Q

bod pod uses new equation to calculate body volume from raw body volume. what factors influence this measurement?

A
  1. thoracic lung volume
  2. lots of puffy hair
  3. wearing warm clothes

(does not affect, total body mass)

38
Q

when all the conditions are the same, if underwater weight is measured higher than actual, the estimated body fat % will be lower than the true value

A

true

39
Q

using DXA we can identify android and gyroid body fat distribution

A

true

40
Q

DXA is based on the principle that weakening of x-ray energies vary

A

true

41
Q

when using bod pod, height and weight are needed to calculate body surface area

A

true

42
Q

what affect will excess clothing have on %body fat measure?

A

will under predict body fat percentage

43
Q

female client, 30 years old, 85.6 kg body weight, 167.2 cm height, 35% body fat. current lean body mass is?

if she reduces to 28%, what is her target weight?

A

55.6 kg, 77.3

44
Q

to evaluate _____ you will measure the same client of DXA

A

validity

45
Q

air displacement plethysmography technique using bod pod follows boyle’s law because of the isothermal condition that the chamber creates

A

false (abiotic conditions)

46
Q

_____ describes the amount of air trapped in lungs after maximal expiration

A

residual volume

47
Q

isothermal condition describes when the temperature of air does not remain constant as the volume changes

A

false

Q

during pnf stretching, contraction of the agonist muscle is designed to activate which sensory organ and cause which reflex action

A

golgi tendon organ, causes reflex muscle relaxation

49
Q

myotatic stretch reflect, and reflex action

A

golgi tendon organ, causes reflex muscle contraction

which of the following describes proper disposal of used cholestech cassettes

A

disposed in the red biohazard bag

53
