Impedance

What is it?

Boditrax uses Bioelectric Impedance Analysis (BIA) to take a measurement of body composition. A safe electrical signal (50Khz, 800µA) is sent through the body via the pressure-contact footpads on the scale platform. Impedance is measured in Ohms and can be defined as the strength and speed of the electrical signal travelling through the body.

Why is it important?

BIA is based on the fact that lean muscle tissue contains high levels of water and electrolytes, and therefore acts as a conductor of an electrical signal. Fat mass is comparatively anhydrous and acts as a resistor to the flow of an electrical signal. Increasing levels of fat mass result in a higher impedance value, and correspond to higher levels of body fat.

Any recommendations?

Remember to read the questions prior to performing a scan. Do not use if you have had a pacemaker or other electrical/magnetic device fitted as the low electrical current can disturb the electrodes and the pacemaker’s generator that sends electrical impulses to the heart.
