The derived anthropometric measures include the mid-upper arm muscle area (MUAMA), the upper arm fat area (UFA), and the arm fat index. The mid-upper arm area (MUAA) is an estimation of the area of the upper arm. It is derived from the MUAC using the following formula: [3] [4] = [3] [4] [6] The mid-upper arm muscle circumference (MUAMC) is an ...

the ratio of hip circumference to shoulder circumference varies by biological sex: the average ratio for women is 1:1.03, for men it is 1:1.18. [9] legs (floor to crotch, which are typically three-and-a-half to four heads long; arms about three heads long; hands are as long as the face. [10]
Typical American adult BRI values range from 3 or less (midsection leanness) to 7 or more (midsection roundness), with a medium index of about 5. [ 1 ] [ 3 ] As a relatively newer predictive metric, BRI has a smaller research record compared to long-established indices like the BMI and waist-to-hip ratio , so its accuracy and applications ...
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

In anatomical usage, the term arm may [3] sometimes refer specifically to the segment between the shoulder and the elbow, [14] [15] while the segment between the elbow and wrist is the forearm. However, in common, literary, and historical usage, arm refers to the entire upper limb from shoulder to wrist.
Arm span or reach (sometimes referred to as wingspan, or spelled armspan) is the physical measurement of the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90° angle. The arm span measurement is usually very close to the person's height.
