- Anthropometric measurement techniques
- measurement of body girths at different sites
- Skinfold thickness
- technique to assess body comp by measuring a double thickniessof skin at specific body sites
- Girth measurements
- technique to assess body composition by measuring circumferences at specific body sites
- Bioelectrical impedance
- technique used to assess body comp by running a weak elec current through body, painless
- Body mass index (BMI)
- a technique to determine thinness and excessive fatness that incorporates height and weight to estimate critical fat values at which the risk for disease increases
- Underweight
- extremely low body weight
- Waist-to-hip ratio (WHR)
- a measurement to assess potential risk for disease based on distribution of body fat
- body composition
- the total fat and non-fat components of the human body; important in assessing recommended body weight
- percent body fat
- proportional amount of fat in the body based on the person's total weight; includes both essential and storage fat; also termed fat mass

- essential fat
- minimal amount of body fat needed for normal physiological functions; constitutes about 3% of total weight in men and 12% in women
- storage fat
- body fat in excess of essential fat; stored in adipose tissue
- dual energy x-ray absorptiometry (DEXA)
- method used to assess body fat composition that uses very low-dose beams of x-ray energy to measure total body fat mass; fat distribution pattern, and bone density
