Mylott et al used bioelectrical impedance to estimate fat-free mass in a student physics laboratory exercise. The authors are from Portland State University.
Parameters:
(1) weight in kilograms
(2) height in centimeters
(3) age in years
(4) sex (1 if male, 0 if female)
(5) resistance in Ohms
fat-free mass in kilograms =
= (0.36 * ((height)^2) / (resistance)) + (0.162 * (height)) + (0.289 * (weight)) - (0.134 * (age)) + (4.83 * (points for gender)) - 6.83
The equation is similar to others based on BIA, including that of Deurenberg et al.
