Abstract:
Introduction. Bioimpedance analysis is a noninvasive, low cost and a commonly used approach
for body composition measurements and assessment of clinical setting. There is a variety of
methods applied for interpretation of measured bioimpedance data and a wide range of
utilizations of bioimpedance in body composition estimation and evaluation of clinical status.
This method is currently becoming more widely used for diagnostics of various pathological
disorders.
Aim of the study. Revealing the conceptual basis and application of bioimpedance, as well as
the method feasibility regarding physiological activity, body composition and chronic diseases
assay.
Materials and methods. Assaying the contemporary models concerning the implementation of
bioimpedance in clinical research, including indirect assessment of physiological functions and
body composition (fluid volumes and fat-free mass), classification of hydration, regional fluid
accumulation, prognosis of disease and wound healing as well.
Results. Increasing request for accurate, cost effective and non-invasive systems for clinical
status monitoring and diagnosis of diseases, has accelerated the research endeavors to provide
new methods and technologies for evaluation of the human body health. Body composition
assessment tools have been considered a promising approach for the quantitative measurement of
tissues characteristics over time, additionally to a direct assay of body composition equivalences
and survival rate, clinical condition, illness and quality of life.
Conclusions. Bioimpedance analysis is a growing method for body compartments estimation in
nutrition studies, sportive medicine and evaluation of hydration rate, fat mass and fat free mass
between healthy and diseased populations. Fat mass, fat free mass including skeletal muscle
mass, bone minerals, and total body water are compartments that can be predicted and analyzed
using suitable bioimpedance measurements techniques, procedures and special equations applied
in population in concern to age, ethnic groups etc.
