Multi-Compartment Models (the Gold Standard)

The most accurate way to measure body composition is thought to be with multi-compartment models. In these models, the body is divided into three or more parts. 3-compartment and 4-compartment models are the most popular types of evaluations.

To estimate body mass, volume, water content, and bone content, these models require a number of tests. This information was compiled using some of the methods already covered in this article. For instance, body water can be determined by BIS or BIA, body volume may be measured by hydrostatic weighing or ADP, and bone content can be measured by DXA. The data from each of these methods is used to create a more comprehensive picture of the body and estimate the most accurate body fat percentage.
