Hydrostatic Weighing Measurements
Hydrostatic measurements are based on the assumption that density and specific gravity of lean tissue is greater than that of fat tissue.
Therefore, lean tissue will sink in water and fat tissue will float. By comparing a test subject's weight measured out of the water and submerged
underwater, body composition can be calculated.
But even the Gold Standard is not flawless. Measurement technique must be strictly controlled. The air remaining in the lungs of a test subject must be accurately determined. You must, as a minimum requirement, estimate the residual volume remaining in the lungs. We recommend # S-1200 "Micro" spirometer.
For most accurate body fat determination you must measure the residual volume. Our model
17400 RV Measurement System will do it for you.
Modern hydrostatic weighing systems are computerized to minimize measurement errors. For more information we can fax or mail you our data sheet No. 17060.
