Abstract
Most devices assessing body composition harbor a number of drawbacks and hardly assess the phenomena taking place at a cellular membrane level. The present single-frequency bioelectrical potential homeostatic structure analysis (PHoSA) technology requires only a proper hands contact on fixed electrodes and determines the phase displacement between tested current and voltage by using a 50-KHz alternate sinusoidal current. This allows quick testing time with high degree of precision, sensitivity, and specificity of sectorial functional body compartments analysis. Such assessment may prove to be an integrated part of either a diagnostic workup or monitoring tool in tailoring nutritional/nutraceutical, pharmacological, and exercise activity, all being framed within a proactive, preventive, age-intervention management strategy.
