, Body Fat Percentage, and Lean Body Mass Estimates Females: Body density
In the first step, body density
was calculated using one of three formulae given below.
The body composition was assessed in each examinee using the technique of skinfolds, where the values of body density
Body fat from total body density
and its estimation from skinfold thickness: measurements on 481 men and women aged from 16 to 72 years.
was estimated using the equations proposed by Jackson and Pollock (1978) and Jackson et al.
was estimated from the Jackson and Pollock equation (14).
Anthropometric equations are required to convert body density
to fat percentage.

decreased markedly at ecdysis, but was also influenced by ration and temperature particularly in nonmolters; the effect of ration on body density
in nonmolters was highly significant.
was estimated from the fat thickness by the Jackson and Pollock equations (12).
