A

Skinfold measurements. Ease of administration and low cost.

16
Q

Why is it extremely important that a trainer demonstrate strong skills and reliability when assessing body composition?

A

A body composition score can be critical to a client’s psyche or motivational levels.

17
Q

Anthropometric measures include what?

A

Measurements of height, weight and/or circumference to assess body size or dimension.

18
Q

When does the margin of error increase with skinfold measurements?

A

When the trainer is unfamiliar with identifying exact skinfold locations or lacks experience or technique in correctly grasping the skinfold site.

19
Q

What is WHR?

A

Waist to hip ratio.

20
Q

Name two common anthropometric measures that demonstrate strong correlations to health, morbidity and mortality.

A

BMI and WHR. These are only estimations.

21
Q

What does body composition refer to?

A

The proportion of lean tissue to body fat tissue.

22
Q

Lean body mass (LBM) is composed of:

A
  • Muscles
  • Connective tissue
  • Bones
  • Blood
  • Nervous tissue
  • Skin
  • Organs
23
Q

LBM means:

A

Lean body mass.

24
Q

A certain amount of body fat is necessary for:

A
  • Insulation and thermoregulation
  • Hormone production
  • Cushioning of vital organs
  • Maintenance of certain body functions
25
Q

What is the normal amount of essential body fat for males and females?

A

Males: between 2 and 5%
Females: between 10 & 13%

26
Q

Where is the remainder of fat, other than essential body fat, stored in the body?

A

Adipose tissue: either subcutaneously or viscerally.

27
Q

Why is it important to differentiate between overweight and overfat?

A

Excess body weight could be attributed to either fat mass or lean tissue.

28
Q

What conditions has excess body fat been linked to?

A
  • CAD
  • Metabolic syndrome
  • Diabetes
  • Breast, colon, and endometrial cancer
  • Osteoarthritis
  • Low back dysfunction
  • Sleep apnea
  • Premature death
29
Q

What percentage of clients join a fitness center and cite weight management as a top reason for their membership?

A

50%.

30
Q

Regarding body composition assessments, what may a trainer need to say to instruct or remind clients?

A

1) Wear appropriate clothing for assessment
2) Clothing may change as body composition changes
3) The scale does not measure body composition changes

31
Q

Explain Bioelectrical Impedence Analysis (BIA).

A
  • Primarily lab setting; less sophisticated devices in fitness setting.
