Body Composition Measurement: Bioelectrical Impedance Analysis (BIA)

Bioelectrical Impedence AnalysisBioelectrical Impedance Analysis (BIA) uses a small electrical current to measure impedance and conductance.  Results include body fat, fat-free mass, and total body water.  The BIA machine uses electrodes that attach to the hand and foot.  The Tanita™ scale requires a standing position without electrodes. The measurement takes approximately 30 seconds to complete.  Prior to each measurement an accurate height and weight are obtained. Shoes and socks must be removed and subjects should be fasting (no foods or beverages) and limit physical activity for at least 2 hours prior to the test.

"Body composition measurements are performed on research participants only and not the general public."
