Anthropometry of The Upper Arm

The anthropometry of the upper arm is a set of measurements of the shape of the upper arms. Large, saggy flaps of skin under the arm are colloquially known as bingo wings, after the phrase was popularised by the comedy television program Bo' Selecta!.

The principal anthropometry measures are the upper arm length, the triceps skin fold (TSF), and the (mid-)upper arm circumference ((M)UAC). 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 and have been used as rough indicators of body fat.

Factors influencing the bone, fat, and muscle composition of the upper arm include age, sex, nutritional status, fitness training level, and race.
