The derived measures include the (mid-)upper arm muscle area ((M)UAMA), the (mid-)upper arm fat area ((M)UAFA), and the arm fat index. Although they are not directly convertible into measures of overall body fat weight and density, and research has questioned the connection between skinfold fat and deep body fat measurements, these measures are ...
Body roundness index (BRI) is a calculated geometric index used to quantify an aspect of a person's individual body shape. Based on the principle of body eccentricity, it provides a rapid visual and anthropometric tool for health evaluation. [1] Introduced in 2013, the BRI calculation can be used to estimate total and visceral body fat.
Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body. Most body water is stored in muscle.
BMI vs. Body Fat Percentage. BMI and body fat percentage are both ways of determining whether a person has a healthy weight or not. A high BMI can indicate a high body fat percentage, but it’s ...

Prior to 1977, bodybuilding had been considered strictly a male-oriented sport. Henry McGhee, described as the "primary architect of competitive female bodybuilding", was an employee of the Downtown Canton YMCA, carried a strong belief that women should share the opportunity to display their physiques and the results of their weight training the way men had done for years.
One easy way to gauge if you have a healthy amount of belly fat is by measuring waist circumference, which is generally considered 35 inches or less for most women and 40 inches or less for most men.
In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. [2]
