The Evolt 360 consists of a body composition analyser which utilises an eight electrode multifrequency segmental analysis known as Biometrical Impedance Analysis. The Evolt 360 body composition analyser uses a scientifically validated test. In other words, those tests are known as Bioelectrical Impedance Analysis (BIA). It is considered the fastest and non-invasive method of screening total body composition. Bioelectrical Impedance (BIA) works by passing a safe, low-intensity electrical current through the body via the feet and hands. The resistance to the flow of the current determines the difference between muscle mass. In addition, fat mass which includes visceral and subcutaneous, water, and minerals.
