16
Q

Target body weight formula

A

Computation of ideal body weight for goal setting
Inputs current weight and desired BF%

17
Q

Using the target weight formula

A

Total weight x %BF (185 * .20)
Total weight - Fat mass (37 lbs)
Lean mass (148 lbs) * Desired %BF (15)
= 170.2

18
Q

Height weight tables were originally designed to

A

Predict mortality rates for insurance premiums

19
Q

Based on too many assumptions, height weight tables possess

A

Significant deficiencies

20
Q

BMI replaced

A

Height weight tables

21
Q

Major issues with height weight tables

A

Tissue composition not identified
Lean mass negatively affects disease prediction
Age variations not factored in

22
Q

BMI provides a single measure to

A

Predict risk for disease and premature mortality

23
Q

BMI does not measure

A

Body fat mass

24
Q

A single measurement for waist circumference can estimate the risk for

A

Cardio-metabolic disease, it examines visceral fat

25
Q

Waist circumference measurement is more useful when combined with

A

BMI

26
Q

Works better than BMI alone for predicting disease risk, but may actually be less effective than waist circumference independently

A

Waist:hip ratio

27
Q

Risk can be underestimated in waist:hip ratio measurement if a person has

A

High levels of lower body fat (gynoid), central obesity is skewed

28
Q

Clinical body composition assessments

A

Dual x-ray absorptiometry
Hydrostatic weighing
Air displacement plethysmography

29
Q

Field body composition assessments

A

Circumference measure
Skinfold measure
Bioelectrical impedance

30
Q

Dual x-ray absorptiometry (DXA) is used in clinical settings to

A

Assess body tissue compartments, including body fat, bone mineral and lean tissue

31
Q

Hydrostatic weighing uses

A

Principle of buoyancy to estimate body composition

32
Q

Air displacement (Bod Pod) uses

A

Air displacement in a specialized chamber

33
Q

Circumference measures are easy to perform, require minimal equipment and are preferred for

A

Obese clients

34
Q

Skinfold measures are preferred for

A

Leaner clients

35
Q
