Abstract

This paper presents our ongoing research in a field of body composition obtained by body impedance analysis. In this work we were focused on changes in bioimpedance in dependence on change of measurement external conditions. This paper also deals with question if data obtained from this method are enough informative with ought any information about the performed measurement. We discovered that it is crucial to have information about the whole measurement procedure and that operator that is performing such measurement should know exact type of device that is used for measurements. Influence of specific conditions did not statistically changed results of calculated values. However in directly measured values resistance and reactance at high frequencies (250 kHz and 500 kHz) were found statistically significant changes (P=0,05) for highly conductive gel. Overall was concluded that external conditions that can be normally encountered at laboratories do not have effect on obtained values. However it is important to know which device was used so the set of used equations are comparable.
