Stimatore Massa Muscolare Scheletrica — Formula
## Skeletal Muscle Mass Estimation
**SMM (kg) = 0.244 x Weight(kg) + 7.80 x Height(m) - 0.098 x Age + 6.6 x Gender - 3.3**
Gender = 1 for male, 0 for female. This calculator uses the male equation.
### Typical SMM Ranges (Male)
| Age | SMM % of Body Weight |
|---|---|
| 20-29 | 40-44% |
| 30-39 | 37-42% |
| 40-49 | 35-40% |

Esempio Risolto
A 30-year-old male, 180 lbs, 70 inches tall.
- Weight = 81.6 kg, Height = 1.778 m
- SMM = 0.244 x 81.6 + 7.80 x 1.778 - 0.098 x 30 + 6.6 - 3.3
- = 19.9 + 13.9 - 2.9 + 6.6 - 3.3 = 34.2 kg
- As % = 34.2 / 81.6 x 100 = 41.9%
