  Bioelectrical Impedance Analysis


Picture
Picture
Picture
Bioelectrical impedance analysis is a tool used in doctor’s offices and health clubs to estimate a person’s fat free mass (FFM) by analyzing a small electrical current. This lab enables students to explore concepts like resistance, reactance, impedance, and phase shift. It also emphasizes the relevance of general physics to pre-health courses. Students use the apparatus to measure known components and then measure the FFM of the body; this makes the applications of the physics apparent to students.
