| Summary: | In Brazil, the beginning of the 21st century has seen the expansion of work groups that focus their academic and professional activities on the analysis of body composition. This study aimed to: Compare the values estimated by the specific equation developed, with the values obtained by the methods of Bioimpedance - BIA (tetrapolar MALTRON 900), Infrared Interactance - NIR (FUTREX 5000 A/ZL) and Hydrostatic Weighing (like Gold Stand). Study is characterized as correlational descriptive research. In the sample, 16 women were used, with an average age of 31.6 (+ 6.4), weight (MCT) of 59.6 (+ 7.8), height of 165.60 (+ 5.6), BIA (tetrapolar MALTRON 900) DE 24.5 (+ 5.6), NIR (FUTREX 5000 A/ZL) 22.3 (+ 5.0) and Hydrostatic Weighing 22.2 (+ 5.7). In the statistical treatment, Student's t-test, paired method and Pearson's Correlation Method were used. The regression model used in this comparison was % F = 0.334 x P. ABD. + 0.315x DC. BICEPS + 0.246 x DC. THIGH – 2.543 x D. BIEST. With EPE (Standard Estimate Error) of 2.7, r (Correlation Index) of 0.99 and R2 (Coefficient of Determination) of 0.99. Comparing the model with the BIA method (tetrapolar MALTRON 900), an r = 0.8 and R2 = 0.7 was obtained, while comparing with the NIR (FUTREX 5000 A/ZL), an r = 0.6 was obtained and R2 = 0.4. It is concluded that, the results seen together, determine that the model presents a greater degree of significance with the BIA method than with the NIR.
