Body-composing constituents and their explanation and function [43].

Body-composing constituents	Explanation and function
Intracellular water (ICW)	Body water which exists inside of cell membrane
Extracellular water (ECW)	Body water that exists outside of cell membrane (blood, interstitial fluid, etc.)
Body water	The sum of intracellular and extracellular water
Protein	Main element which composes soft lean mass together with water
Soft lean mass (SLM)	Skeletal muscle and smooth muscle Maintaining body function
Minerals	Composing bones and electrolytes
Lean body mass (LBM)	Composed with soft lean mass and minerals; The amount of body weight minus body fat mass
Body fat	The amount of body weight minus lean body mass
Weight	The sum of lean body mass and body fat mass. Standard weight (kg): adult male height (m) × height (m) × 22 female height (m) × height (m) × 22
