The most accurate estimation of body composition is derived from body density by means of the equation of fractional densities which states that the overall density of a mixture containing more than one substance each with a different density can be calculated if the proportion and density of each component substance is known. Criterion methods measure a property of the body such as its density or describe amounts and distributions of skeletal muscle.
