We are arizonas leading provider of turn key fitness measurement and tracking services. 1 hydrostatic underwater weighing has been considered the gold standard for body composition assessment. The bod pod is an air displacement plethysmograph which uses whole body densitometry to determine body composition fat and. Lean mass bone muscle connective tissue and organs is more dense than water while fat is less dense. Hydrostatic or underwater weighing is a form of estimating body fat percentage in which a person is completely submerged in a pool of water. Muscle and bone density tracking.
Visceral fat measurement accuracy. On the tails of the hydrostatic weighing method is a revolutionary body composition weighing method known as the dexa dxa scan. This scan from dexafit is designed to not just measure the amount of body fat youre carrying but also tell you where it is in the body. This relies on some fun math having to do with measuring the density of your body in water. Similar to hydrostatic weighing air displacement plethysmography adp estimates your body fat percentage based on the density of your body. In the case of body composition testing lean mass is denser than water while fat mass is less dense than water.
To calculate body fat percentage add your waist and hip measurements and then subtract the neck measurement to determine your circumference value. It measures a persons total body density using archimedes principle of displacement. Easy test process with immediate results. Only body fat testing method that measures every square inch of your body rather than only taking samples or using formulas. We use the bod pod along with other measurement techniques to measure and track fitness levels for professional teams prep athletes cross fit groups and dedicated individuals. As its name suggests hydrostatic testing involves the submersion of the test subject into a tank of water.
Skinfold calipers cannot measure visceral fat. Only body fat method that provides measurements and progress tracking of specific areas of the body such as arms legs and trunk. Hydrostatic underwater weighing or hydrostatic testing is a method of determining body composition body fat to lean mass. Therefore a person with more fat will weigh less under water than someone with more muscle. For example if your waist is 30 your hips are. Hydrostatic weighing borrows archimedes principle in physics to measure body fat and lean mass through full underwater submergence.
However adp uses air instead of water. The dexa scan is the most accurate method for body composition analysis. Muscle is denser than fat which helps practitioners of this technique calculate body composition. Hydrostatic weighing is a method of determining body fat percentage where you are weighed in and out of water.
