Question 1

Assumptions for bioelectrical impedance method are

Answer 1

Fluids conduct electricity

Approximately 73% of body water is contained in fat free body mass

Your body is a perfect cylinder

Muscle cells contain water therefore conducting well

Question 2

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

Answer 2

Residual volume

Question 3

The assumed amount of gas trapped in the gasstrointestinal system when you use hydrostatic weighing method to assess body composition is approx

Answer 3

0.1L

Question 4

One of the assumptions of the skinfold method is that measuring skinfold thickness at multiple sites provides a good measure of subcutaneous fat. This assumption reflects which measurement concept

Answer 4

Validity of the skinfold method

Answer 5

False

Question 6

Answer 6

True

Question 7

Using IDXA from our lab, we can identify the android and or gynoid type of body fat distribution

Answer 7

True

Question 8

Dehydration state of the body misleads the bia result by overestimating on body fat

Answer 8

True

Question 9

As the sum of skinfolds increases, the density of the body increases

Answer 9

False

Question 10

Using durin and Womersley table, you can estimate % body fat by calculating the sum of biceps, triceps, subscapular and suprailliac folds

Answer 10

True

Question 11

Air displacement plethysmography techinque using bod pod follows Poissons law because of the isothermal condition that the chamber creates

Answer 11

False

Question 12

Using bod pod % body fat is calculated based on Siri equation following a two component model

Answer 12

True

Question 13

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

Answer 13

False

This is body volume

Answer 14

True
