Bioelectrical impedance technique is a non-invasive method used to acquire human biomedical data from electric property and its changes of tissues and organs. This paper introduced the principle and research methods of bioelectrical impedance technique, reviewed the application of bioelectrical impedance technique and analyzed the feasibility of bioelectrical impedance technique applied in sports science. Studies suggest that in measurement of body composition, blood and hemodynamics, the application of bioelectrical impedance technique can be used for reference in sports science; Electric imp...
