Measurement of body composition
Measurements of body composition, such as LBM and BFM, were obtained using a InBody S10 body composition analyzer (InBody Co., Ltd., Seoul, Korea) in the sitting position. Thirty bioimpedance measurements were based on six different frequencies (1 kH, 5 kHz, 50 kHz, 250 kHz, 500 kHz, and 1000 kHz) at each body segment (right arm, left arm, trunk, rightleg, and left leg).
