The devices send an imperceptible electrical charge through hardcore fatties the body to measure its bioelectrical hardcore fatties impedance or resistance. The underlying principle is electricity travels differently through the water that surrounds fat and muscle cells than it does through bone or the cells themselves. Continue article Advertisement During BIA, electrodes are placed on the wrist and ankle while a low electrical current is passed through the body. The change in voltage between the electrodes is measured. That figure is then used to calculate total body water. The water value can then be used to infer total body fat based on a manufacturer-supplied formula that considers the subject's age, gender, height and weight. Because of the widespread interest in body composition by the fitness-minded and health-care professionals, NIH convened a technology assessment conference to evaluate the validity of BIAs for body composition estimation. |

| In a study bbw xxx sponsored by the National Institute of Health (NIH), scientists at the National Institute of Standards and Technology bbw xxx (NIST) recently found that the results from electronic instruments designed to estimate body fat vary widely from known standards. Such tools, known as bioelectrical bbw xxx impedance analyzers (BIAs), are in routine use by health clubs, hospitals, athletes, dieters and dialysis clinicians to obtain body fat estimates. They are quick, simple, noninvasive and relatively inexpensive. The results given by the machines were off by as much as 40% in some cases. The conclusion was that such wildly divergent results are due to lack of industry standards. Recognizing the importance of BIAs in assessing body composition of healthy individuals, as well as those with certain chronic conditions, the NIH panel expressed concern about the lack of standardization of these devices. Contrary to popular belief, these tools do not measure actual body fat content. |
