Research and Evaluation on Body Composition Measurement System Based on Bioelectrical Impedance

Objective： this paper discusses the effect of bioelectrical impedance measurement system of human body composi- tion measurement and applicability. To measure body composition when choosing the appropriate measurement system pro- vides the technical support and theoretical basis. Methods： carried on the thorough research and evaluation on the bioelectrical impedance measurement system, analysis and summarized the problems of bioelectrical impedance measurement system, and the influence factors of biological electrical impedance on measuring body composition has carried on the induction and sum mary, finally, the future development of the biological electrical impedance measuring body composition was prospected. Re sults： bioelectrical impedance measurement system has experienced from single frequency whole-body measurement system to multiple frequency body segmentation measurement of the electrical impedance measurement system, the characteristics of the measurement system and external factors that will have some interference to the entire measurement system, so according to different need to choose the appropriate measurement system and measurement scheme can minimize interference. Conclu sions： The bioelectrical impedance method is an ideal method to measure body composition, the choice of measurement system is the key to human body composition measurement. With the research advancement, there will be suitable for partial body electrical impedance measurement system.
