In the Densitometry Method of Body Composition Analysis?

Here, body composition is derived from body density, or Densitometry. In densitometry, the more dense a body is, the lower the percentage of body fat (as fat free tissue is more dense than fat); the less dense a body is, the higher the percentage of body fat (Density = Mass/Volume).

Does densitometry measure body composition?

Densitometry provides a two-compartment model, measuring FM and FFM. Densitometry measures body mass and volume and calculates body density by using Siri's equation for Caucasian populations [% fat = 4.95/(D – 4.5) × 100] and Shuttle's equation for African Americans [% fat = 4.374/(D – 3.928) × 100]. ...

What is densitometry how is it used to assess the body composition of the athlete what is the major weakness of densitometry with respect to its accuracy?

Densitometry was developed to measure body composition. Using underwater weighing, or hydrostatic weighing, a person is submerged in water and body weight is accurately measured before and after submersion. There are many weaknesses with this method such as the composition of FFM can change after weight training.
