Standing-posture 8-electrode bioelectrical impedance analysis is a fast and practical method for evaluating body composition in clinical settings, which can be used to estimate percentage body fat (BF%) and skeletal muscle mass in a subject's total body and body segments. In this study, dual-energy X-ray absorptiometry (DXA) was used as a reference method for validating the standing 8-electrode bioelectrical impedance analysis device BC-418 (BIA, Tanita Corp., Tokyo, Japan). Forty-eight Taiwanese male wrestlers aged from 17.9 to 22.3 years volunteered to participate in this study. The lean soft tissue (LST) and BF% in the total body and body segments were measured in each subject by the BIA and DXA. The correlation coefficients between total body, arm, leg segments impedance index (BI, ht/Z) and lean soft tissue mass measured from DXA were r = 0.902, 0.453, 0.885, respectively (p < 0.01). In addition, the total body and segmental LST estimated by the BIA were highly correlated with the DXA data (r = 0.936, 0.466, 0.886, p < 0.01). The estimation of total body and segmental BF% measured by BIA and DXA also showed a significant correlation (r > 0.820, p < 0.01). The estimated LST and BF% from BIA in the total body and body segments were highly correlated with the DXA results, which indicated that the standing-posture 8-electrode bioelectrical impedance analysis may be used to derive reference measures of LST and BF% in Taiwanese male wrestlers.
站立位八电极生物电阻抗分析是临床环境中评估身体成分的一种快速实用的方法，可用于估计受试者全身及身体各部位的体脂百分比（BF%）和骨骼肌质量。在本研究中，双能X线吸收法（DXA）被用作验证站立位八电极生物电阻抗分析设备BC - 418（BIA，日本东京百利达公司）的参考方法。48名年龄在17.9至22.3岁之间的台湾男性摔跤运动员自愿参与本研究。通过BIA和DXA测量了每位受试者全身及身体各部位的瘦软组织（LST）和BF%。全身、手臂、腿部的阻抗指数（BI，身高/阻抗，ht/Z）与通过DXA测量的瘦软组织质量之间的相关系数分别为r = 0.902、0.453、0.885（p < 0.01）。此外，BIA估计的全身及各部位LST与DXA数据高度相关（r = 0.936、0.466、0.886，p < 0.01）。BIA和DXA测量的全身及各部位BF%估计值也显示出显著相关性（r > 0.820，p < 0.01）。BIA估计的全身及身体各部位的LST和BF%与DXA结果高度相关，这表明站立位八电极生物电阻抗分析可用于得出台湾男性摔跤运动员LST和BF%的参考测量值。
