  Purpose
The aim of the study is to generate normal ranges for φ, BIVA and BCC. The calculation of FMI and FFMI is based on the results of two other clinical investigations: "Generation of prediction equation to analyze body composition of adults based on Bioelectrical Impedance Analysis (BIA)" (BCA-01) and "Application and adaption of device specific body composition formulas to various ethnic groups" (BCA-02). The aim of BCA-01 was to develop prediction equations for calculating FFM, TBW, ECW and SMM based on the gold standard reference methods ADP, DXA, MRI, D2O and NaBr on the one hand and measurement data of the BIA devices on the other hand. The equations are necessary to use the device as a Body Composition Analyzer with an acceptable accuracy level for clinical practice. The aim of the study BCA-02 was to apply and adapt device specific body composition formulas to various ethnic groups.

Primary Outcome Measures:
  • Bioelectrical Impedance of 1, 1.5, 2, 3, 5, 7.5, 10, 15, 20, 30, 50, 75, 100, 150, 200, 300, 500, 750 and 1,000 kHz [ Time Frame: about 15 minutes ]
    The measurement is planned to be done for all body segments: right arm, left arm, right leg, left leg, trunk, right body side and left body side. In total resistance and reactance at 19 frequencies for 7 body segments are planned to be measured.


Secondary Outcome Measures:
  • Verification of equivalence to a predicate device in accordance to Premarket Notification [510(k)] process of the FDA for product approval in the U. S. [ Time Frame: about 15 minutes ]
    Predicate Device: BIOSPACE INBODY 720
