Abstract

Anti-aging medicine has been more emphasized in developed countries. For detecting sarcopenia and frailty, bioelectrical impedance analyses (BIA) have recently attracted attention. From BIA by InBody, useful data of water balance, muscle index, and cellular health can be obtained as extracellular water/total body water (ECW/TBW), skeletal muscle mass index (SMI), and phase angle (PhA). PhA shows a close relationship with exercise habits and physical activity. The cut-off values of PhA are approximately 4.05° to 5.05°, which are related to sarcopenia. Average PhA values in males/females showed 7.7°/6.9° in university athletes and 4.1°/3.6° in aged people of 81 years old.
