Body fat percentage

body fatfat masspercentage body fat
A reasonably accurate estimation of body fat can be obtained by means of a "two compartment model" of the human body which is based upon two simplifying assumptions: 1. Human fat has a density of 0.9 grams/ml, and 2.
The body fat percentage is a measure of fitness level, since it is the only body measurement which directly calculates a person's relative body composition without regard to height or weight.

Air displacement plethysmography

The technique uses air as opposed to water and is known as air displacement plethysmography (ADP).
Air displacement plethysmography or ADP (also known as whole-body air displacement plethysmography) is a recognized and scientifically validated densitometric method to measure human body composition.

Bioelectrical impedance analysis

Another method is bioelectrical impedance analysis (BIA), which uses the resistance of electrical flow through the body to estimate body fat.
Bioelectrical impedance analysis (BIA) is a commonly used method for estimating body composition, and in particular body fat.

Body mass index
BMI was designed to be used as a simple means of classifying average sedentary (physically inactive) populations, with an average body composition.

Body volume is combined with body weight (mass) in order to determine body density.

Creatinine

Creatinine height ratio is calculated as 24-hour urine creatinine multiplied by 100 over the expected 24-hour urine creatinine for height.

Internal consistency

(See internal consistency for merits on testing in this manner.) If an individual is to be tested from one period to the next, all factors should ideally remain as similar as possible to reflect the best indicator of true change in composition.

Behnke is also known as the "modern-day father" of human body composition for his work in developing the hydrodensitometry method of measuring body density, his standard man and woman models as well as a somatogram based on anthropometric measurements.

Lightweight rowing

Although lightweight rowing is the counterpart to heavyweight rowing, it is a fairly different sport, relying much more on ideal body composition and technique than raw strength.

Journal of Cachexia, Sarcopenia and Muscle

The Journal of Cachexia, Sarcopenia and Muscle is a quarterly peer-reviewed medical journal that covers research relevant to changes in body composition, especially cachexia and sarcopenia, as consequences of chronic illnesses or of the aging process, respectively.

Basal metabolic rate

BMR typically declines by 1–2% per decade after age 20, mostly due to loss of fat-free mass, although the variability between individuals is high.

Paternal care

paternal investmentMale parental careparental care
For example, mammalian fathers that care for their young may undergo systematic changes in body mass and in circulating or excreted concentrations of a number of hormones (e.g., androgens, glucocorticoids, leptin) as a function of reproductive status, and several of these hormones have important effects on body composition, metabolism, and organismal performance.

Growth hormone deficiency

Body composition (i.e., the relative amounts of bone, muscle, and fat) is affected in many children with severe deficiency, so that mild to moderate chubbiness is common (though GH deficiency alone rarely causes severe obesity).
