Figure 1: Illustration of body composition (a) as body compartments, and (b) in relation to assessment tools reflecting the compartments tested. (a) FM and FFM are two broad compartments. FFM constitutes cellular tissue, TBW that includes ECW and ICW, and bone mineral content. (b) BMI and MAC reflect both FM and FFM. Dual X-ray absorptiometry is a reference tool for the bone compartment. FFM, FM, and TBW can be estimated using BIA. FM is assessed by DXA, BIA, and SFT. BCM and ECM can be estimated by BIVA and WBPC. FM: Fat mass, FFM: Fat-free mass, ECW: Extracellular water, ICW: Intracellular water, BMI: Body mass index, MAC: Mid-arm circumference, DXA: Dual X-ray absorptiometry, BIA: Bioimpedance analysis, SFT: Skin fold thickness, BCM: Body cell mass, ECM: Extracellular mass, WBPC: Whole-body potassium counter
