Cunningham used equations for estimating the lean body mass of normal adults. The author is from Brown University.
The equations are derived from:
(1) equation of Moore et al for total body water
(2) equation of Pace and Rathbun stating that total body water is a fraction of lean body mass
Parameters:
(1) age in years
(2) gender
(3) body weight in kilograms
(4) total body water in liters
lean body weight for a male adult =
= (79.45 – (0.24 * (body weight)) – (0.15 * (age))) * (body weight) / 73.2
lean body weight for a male adult =
= (69.81 – (0.26 * (body weight)) – (0.12 * (age))) * (body weight) / 73.2
