Bioelectric Impedance Analysis study guide 1. What is impedance as it relates to an electrical current? The current passes freely through the fluids contained in muscle tissue, but encounters difficulty/resistance when it passes through fat tissue. 2. Which has the lowest impedance – muscle or fat? Muscle 3. What is the definition of: a. Impedance – the degree to which a medium slows or stops an applied current b. Resistance – a measure of the amount of electrical current a substance will stop c. Reactance – a measure of a material’s ability to slow a current 4. What happens to an electrical current in adipose tissue? Only a small amount of current passes through the adipose tissue. Therefore, adipose tissue is said to have a high impedance. 5. Let’s assume you want to measure extracellular fluid. Would you use a high or low frequency current? Low frequency 6. Why do we use a frequency of higher than 50 KHz when assessing body composition?
