skeletal_muscle_mass: Predict skeletal muscle mass.

Description

Predict skeletal muscle mass from age, height, and gender.

Usage

skeletal_muscle_mass(smm, age_years, height, gender)

Arguments

smm

Vector of allometrically-scaled skeletal muscle masses.

age_years

Vector of ages in years.

height

Vector of heights in cm.

gender

Vector of genders, either 'Male' or 'Female.'

Value

Vector of skeletal muscle masses in kg.

Details

For individuals over age 18, use allometrically-scaled muscle mass with an age-based scaling factor, to account for loss of muscle mass with age (Janssen et al. 2000). For individuals under age 18, use skeletal_muscle_mass_children.
