BIOLECTRIC IMPEDANCE Meaning and
Definition
-
Bioelectric impedance (BIA), also referred to as bioelectrical impedance analysis, is a technique used to assess the body composition of an individual by measuring the resistance encountered by an electrical current as it passes through the body. This non-invasive method is based on the principle that different tissues and fluids in the body conduct electrical currents at different rates due to their varying degrees of water, electrolyte, and fat content.
By passing a low-frequency electrical current through the body using electrodes placed on the skin, BIA devices can measure the impedance (resistance) encountered by the current, which is affected by the composition of the body. The resistance is then used to calculate various parameters related to body composition, including total body water, fat mass, fat-free mass, and skeletal muscle mass.
BIA is commonly used in fitness and health settings to estimate body fat percentage, monitor changes in fat-free mass, and evaluate hydration levels. It is particularly valuable due to its ease of use, affordability, and the fact that it does not require radiation exposure or extensive training to perform. However, it should be noted that BIA may have limitations and sources of error, including sensitivity to hydration status, variability between different BIA devices, and population-specific equations.
Overall, bioelectric impedance is a valuable tool for assessing body composition and monitoring changes over time, providing valuable information for individuals and professionals involved in fitness, nutrition, and medical fields.

Etymology of BIOLECTRIC IMPEDANCE
The word "Biolectric Impedance" is a combination of two scientific terms: "bioelectric" and "impedance".
The term "bioelectric" refers to electricity or electrical potentials generated by living organisms. It comes from the combination of two words: "bio" meaning life or living organisms, and "electric" referring to the electrical energy or phenomenon.
The term "impedance" refers to the opposition or resistance to the flow of electric current in a circuit. It is a property that represents the combined effects of resistance, capacitance, and inductance.
Therefore, "bioelectric impedance" refers to the measurement or analysis of electrical currents in living organisms, usually used to estimate body composition, such as body fat percentage or muscle mass.
