How the Biodyxpert impedance analyzer works
Body composition refers to the distribution of fat mass, skeletal muscle mass, and water in the body, providing a much more relevant assessment than just weight or BMI.
Bioelectrical Impedance Analysis (BIA) is a non-invasive and painless method that allows for the analysis of these compartments. It is based on how the body's tissues react to a very low-intensity alternating electrical signal, imperceptible to the individual.
This response depends significantly on tissue hydration and cell membrane properties. By integrating these parameters into validated predictive models, bioelectrical impedance analysis (BIA) allows for the estimation of fat-free mass and its associated compartments, notably skeletal muscle mass and total body water.
Bioelectrical Impedance Spectroscopy (BIS) goes even further: it measures the body's electrical response across a broad frequency spectrum, enabling finer characterization of fluid compartments and cellular properties (such as membrane capacitance and characteristic frequency). This spectroscopic approach enhances the physiological robustness of the model and provides direct quality control through signal coherence analysis across the entire spectrum.
Thanks to their ease of use and the speed of obtaining results, BIA and BIS provide essential information on nutritional and hydration status, constituting reliable tools for clinical monitoring.
Bioelectrical impedance analysis (BIA) is strongly correlated with total body water, allowing for accurate estimation of fat-free mass using predictive equations. In contrast, since adipose tissue is very weakly correlated with the measured parameters, its direct estimation is less reliable. Thus, there is a scientific consensus to calculate fat mass by difference, subtracting fat-free mass from total weight, in accordance with the body compartment model.
Parameters derived from the bioelectrical signal
Beyond estimates derived from body composition models, certain parameters are calculated directly from the measured electrical signal. These so-called "raw" indicators are not based on predictive equations but rather reflect the intrinsic electrical properties of biological tissues.
Phase angle (PhA)
The phase angle is derived from the relationship between resistance (R) and reactance (Xc). It reflects the capacitive behavior of cell membranes and is a global indicator of membrane integrity and active cell mass.
At a physiological level, the phase angle (pH) reflects the ability of cells to maintain their structure, intracellular hydration, and function. A decrease in the phase angle can be associated with tissue damage, fluid imbalance, or a catabolic state. Monitoring it over time provides valuable qualitative information about the evolution of the cell's state.
Impedance ratio (IR)
The impedance ratio (IR) is generally expressed as the ratio between the impedance measured at high frequencies and the impedance measured at low frequencies. It provides additional information about the distribution of body fluids.
The RI allows for the evaluation of the balance between intracellular and extracellular compartments, as well as the structural coherence of tissues. An elevated RI may reflect a change in membrane permeability or an alteration in water distribution.
The combined interpretation of pH and RI strengthens the physiological robustness of the analysis. These parameters enrich the clinical evaluation by providing a qualitative reading of biological tissue, beyond the simple quantitative estimation of fat or muscle mass.
