Air displacement plethysmography (ADP, also known as whole-body air displacement plethysmography) is a recognized and scientifically validated densitometric method to measure human body composition. ADP is based on the same principles as the gold standard method of hydrostatic weighing , but through a densitometric technique that uses air ...
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).

Hydrostatic weighing, also referred to as underwater weighing, hydrostatic body composition analysis and hydrodensitometry, is a technique for measuring the density of a living person's body. It is a direct application of Archimedes' principle , that an object displaces its own volume of water.
It is a scientific discipline that is concerned with the measurement of individuals in a variety of morphological perspectives, its application to movement and those factors which influence movement, including: components of body build, body measurements, proportions, composition, shape and maturation; motor abilities and cardiorespiratory ...
Nearly 25 years after her death, details of Audrey Hepburn's life are still coming to light. In an interview withPeople, the legendary actress' family opens up about her life behind closed doors ...
While we assumed that Hepburn's ballet training kept her so slender, her youngest son Luca Dotti, 45, writes in his new book, Audrey at Home: Memories of My Mother's Kitchen, that the star's ...
In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. [8] Water is ~11% hydrogen by mass but ~67% hydrogen by atomic percent , and these numbers along with the complementary % numbers for oxygen in water, are the largest contributors to ...
The truth behind the actress' figure is more sinister than diet and fitness.
