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 impedance tomography enables non-invasive, real-time and dynamic monitoring of structures and functions of human organ and tissue under sports. The appreciable strategy for bioelectrical impedance technique application in sports science is to establish reliable and steady correlative models or regressive equations between bioelectrical impedance and physiological parameters of sports human for further study using statistical principles.
