Method. The procedure is based on Archimedes’ principle, which states that: The buoyant force which water exerts on an immersed object is equal to the weight of water that the object displaces.Click to see full answer. Hereof, how is hydrostatic weighing performed?Hydrostatic weighing, also known as Hydrodensitometry or underwater weighing, is a classic measure of body composition. The test involves the subject being lowered into a water tank until all body parts are emerged, expelling all the air from the lungs, then weighed.One may also ask, how accurate is hydrostatic body fat testing? Availability: Hydrostatic weighing is typically only available at universities, medical settings or certain fitness facilities. Accuracy: When testing is performed perfectly, the error of this device can be as low as 2% body fat (3, 10). Then, how long is hydrostatic weighing? The scan uses two X-ray beams that scan the body for between 10-20 minutes. The scan measures both bone density and full body composition in an easy, non-invasive way. The entire procedure is done in under 30 minutes and afterward, you can return to your normal daily activities.What is the real advantage of hydrostatic weighing?Hydrostatic weighing is a method of determining body fat percent. The real advantage to hydrostatic weighing is that it B. gives one of the most accurate measurements of body fat.
