Quantities of fat mass and fat free mass by running a small electrical current through the body. The objective of this conference was to provide physicians with a responsible assessment of bioelectrical impedance analysis bia technology for body composition measurement.
Body Composition Testing Science For Sport
Bioelectrical impedance analysis in body composition measurement. This is possible simply because different bodily tissues eg. Translating bioimpedance measures into body volumes and masses ie conventional bia and generating the impedance vector by using the r and xc obtained at a frequency of 50 khz to match it against that of the healthy reference population ie biva sánchez iglesias et al 2012. Muscle fat bone etc all have varying amounts of water content and as a result they all differ in terms of electrical conductivity. Bioelectrical impedance analysis bia is a commonly used method for estimating body composition in particular body fat and muscle massin bia a weak electric current flow through the body and the voltage is measured in order to calculate impedance resistance of the body. Bioelectrical impedance analysis bia is a widely used method for estimating body composition. Bia is currently used in diverse settings including private clinicians offices health clubs and hospitals and across a spectrum of ages body weights and disease states.
There are also two different ways to interpret the bioelectrical measurements in terms of body composition. Bioelectrical impedance analysis bia and body composition analyse as a physician you know that the body mass index bmi by itself is no t sufficient to analyze a patients health status and body composition thoroughly. Bioelectrical impedance analysis in body composition measurement. Fat muscle water and other important indicators of underlying medical conditions are not considered in the bmi. Bioelectrical impedance analysis bia is able to make an estimation of body composition eg. National institutes of health technology assessment conference statement.
The american journal of clinical nutrition 64 524s532s. Most body water is stored in muscle. Participants were a non federal nonadvocate 13 member panel representing the fields of nutrition pediatrics surgery public health biomedical engineering epidemiology and biostatistics. The technology is relatively simple quick and noninvasive.
