Analysis of body composition by multiple and single frequency method in the elderly. Exercise Science, 13(2): 263-272, 2004. The purpose of this study was to compare estimates of body composition determined from single-frequency bioelectrical impedance methods (S-BI) and multi-frequency bioelectrical impedance method (M-BI). The body composition was assessed by dual energy X-ray absor- ptiometry (DXA), 4 brands of S-BI (TBF-300, GIF-891DX, HBF-300, HTM-1000) and 1 brand of M-BI (InBody 3.0). Sixty eighty elderly, aged 62-80 years, served as subjects. The S-BI and M-BI FFM estimates were highly correlated with the FFM measured by DXA (FFMDXA) (r=0.89-0.91) as criterion method. The standard errors of estimate (SEE) for FFM were 2.1-2.88 kg. With the exception of the TBF-300 and HK, all brands of BI slightly overestimated or overestimated FFM. The absolute mean differences between FFMDXA and each of the 5 BI estimates ranged from -1.3 kg to +1.1 kg. Although the 5 brands of BI provided slightly different estimates, the results of this study suggest that S-BI and M-BI are relatively valid in assessment of body composition in Korean elderly. |
