Lean Body Mass vs Body Weight
Formula
## Boer Formula for Lean Body Mass (Male) **LBM (kg) = 0.407 x Weight(kg) + 0.267 x Height(cm) - 19.2** The Boer formula estimates lean body mass directly from height and weight without requiring a body fat measurement. It is considered one of the more accurate predictive LBM equations.
Exemplo Resolvido
A 180 lb, 70-inch tall male.
- 01Weight = 81.6 kg, Height = 177.8 cm
- 02LBM = 0.407 x 81.6 + 0.267 x 177.8 - 19.2
- 03= 33.2 + 47.5 - 19.2 = 61.5 kg (135.6 lbs)
- 04Est body fat = (1 - 61.5 / 81.6) x 100 = 24.6%
Perguntas Frequentes
What is the Boer formula?
The Boer formula (1984) estimates lean body mass from height and weight. It has separate equations for males and females and is widely used in clinical settings.
How does this differ from the simple LBM formula?
The simple method requires knowing body fat percentage. The Boer formula estimates LBM directly from height and weight using regression coefficients.
Why is lean body mass useful?
LBM is used for medication dosing, estimating metabolic rate, and tracking body composition changes independent of total weight.
