Bioimpedance analysis (BIA) has been used to determine body composition since the 1970s. It involves passing a low-intensity alternating electrical current through the body and measuring the resistance of tissues to the current. The impedance, phase angle, resistance and reactance values collected by the measuring device enable the body compartments crossed by the current to be determined through algorithms, providing — depending on the type of device — a more or less precise and detailed result of body composition. The current used is of very low intensity and is completely painless.
