ABSTRACT:The purpose of this study was to determine the predictive accuracy of the Bioimpedance (BIA) method for the assessment of the body composition of 95 Brazilian pos-menopause women (62.27 ± 7.69 years). The BIA method is relatively not expensive, fast and not invasive (LUKASKI, 1987). However, the validity of this method has never been tested in older Brazilian women. Moreover, CHUMLEA & BAUMGARTNER (1989) do not recommend the use of the hydrostatic weighing in older individual. Thus, the DXA (DPX-IQ, Version 4.6) was used to obtain the reference relative fat (%BF), and the fat free mass (FFM). The total body resistance was measured with a BIA RJL model. The LOHMAN (1992) specifi c equation for elders, and the SEGAL et al. (1988) fatness specifi c equations (obese > 30%BF and not obese < 30%BF) were analysed in this study. The results were as follows: The LOHMAN et al. (1992) BIA equation presented a good validity coeffi cient (r = 0.88), an excellent standard error of estimation (SEE = 2.01 kg). However, the LOHMAN equation signifi cantly overestimated the FFM of the studied sample (D = -0.63 kg). However, the BIA equations of SEGAL et al. (1988) accurately estimated the FFM of the studied sample (D = 0.40 kg), and presented an acceptable error (SEE = 2.11 kg). Based on these results, it can be recommended to physical education professionals, endocrinologists and nutritionists the use of the BIA method for the assessment of the body composition of Brazilian menopause women.Keywords: Body composition, Bioimpedance, Menopause, DXA SQSW, 306/BL.F/ Apt. 109 -Brasília -DF -CEP 70376-000 [97][98][99][100][101][102] Naturally, always that is mentioned on corporeal composition think that is reserved exclusively for athletes, so is the performance from the athlete is partially influenced by the proportion of corporeal fat (CG) and the thin corporeal mass (MCM) (BOTTARO et al., 2002). With all, the corporeal composition is an important aspect on the health from the individuals, independently of the age, sex, and ethnical source. According with the American College of Exercise Medicine (2000), the obesity is linked to an enlargement on the risk of developing cardio vascular disease, hypertension, diabetes, certain types of cancer and many other chronic diseases.The classic model from two components from the SIRI (1961) and BROZEK et al., (1963), which separate the total corporeal mass (MCT) in corporeal fat (CG) and in thin corporeal mass (MCM), is being used on obtaining the measures of references from the corporeal composition. The model from two components is based on the following suppositions: a) the fat density is at 0.901 g/cc; b) the MCM density is at 1.10 g/cc and c) the MCM contains 73.8% of water, 19.4% of protein and 6.8% of mineral (BOTTARO, 2000). It is known that the water proportion, proteins, and mineral on the MCM and consequently, the thin corporeal mass density (dMCM) varies according with the age, sex, ethnic, levels of corporeal fat, and levels of physical activities (BAUMGARTNER et al., 1991;...
