In body measurement (bioelectrical impedance analysis (BIA)), a weak, high-frequency alternating current is passed through the body via electrodes on the hands and feet. This allows the following parameters to be measured:
- Ratio of total body weight, skeletal muscle mass and body fat mass
- Percentage body fat and respective recommended normal range
- Distribution of lean mass, fat and water separately for arms, legs and torso
- extracellular water ratio
- visceral fat in c m²
- phase angle
