In httk: High-Throughput Toxicokinetics

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.'

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.

Value

Vector of skeletal muscle masses in kg.
