Body Composition and Hydration Assessments

Modern medicine has definitely abandoned body weight as the prime metric for nutritional health. First it was replaced by BMI (the body mass index), still a very useful indicator, but body composition now clearly has become the “golden standard”.

Bio-electrical impedance analysis (BIA) is a fast, reliable, affordable and non evasive technique to measure body composition. Its accuracy and dependability have been scientifically proven and clinically demonstrated time and time again. It uses the fact that tissue types differ in electric conductivity. Bones and fat, for instance are bad conductors. Skeletal muscles on the other hand, due to their water and electrolyte content, have much lower impedance. BIA makes it possible to precisely determine the distribution of the individual components, e.g. fluids (“water”), muscle mass and fatty substance in the body.

Is a state-of-the-art fully digital, phase sensitive, 4 channel impedance measuring device. Each channel applies a 50 Hz AC to precisely measure resistive and capacitive impedance as well as phase angle (PA).

By means of its 4 capturing interfaces it can simultaneously record the values for the body as a whole, the trunk, the arms and the legs. This helps pinpoint peripheral fluid retention and enables a more precise anatomical assessment.

Eight electrodes are attached to the test person’s hands and feet. The resulting measurements (resistive and capacitive impedance) as well as anthropometric data are manually entered on or automatically transferred to a computer, where they are duly interpreted by the software. The results are available for immediate consultation.
