Abstract

Bioelectrical impedance analysis (BIA) has been evaluated for water balance, muscle function and fat disposition. By applying BIA, important biomarkers are calculated such as total body water (TBW), extracellular water (ECW), ECW/TBW and phase angle (PhA). Elderly tends to show higher ECW/TBW and lower PhA, because of decreased cell function, edematous situation and less muscle function. Compared study was conducted for two cases of males aged 68/77 years old with same stature. The results of case 1/2 showed skeletal muscle mass index (SMI) 8.0/6.5 kg/m², ECW/TBW 0.368/0.399, PhA 7.8/4.7, respectively. These results suggest expecting research development in this field.
