Bio-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition, the measurement of body fat in relation to lean body mass.It is an integral part of a health and nutrition assessment. Research has shown that body composition is directly related to health.io-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition, the measurement of body fat in relation to lean body mass.
Electrical impedance. An AC supply applying a voltage V {\displaystyle \scriptstyle V} , across an impedance Z {\displaystyle \scriptstyle Z} , driving a current I {\displaystyle \scriptstyle I} . Electrical impedance is the amount of opposition that a circuit presents to current or voltage change. The two main ways to write an impedance are: (see the 2nd figure, complex impedance plane) with the resistance R (real part) and the reactance X (imaginary part), for example Z = 1 + 1 j {\displaystyle Z=1+1j}.
