PURPOSES: To compare different assessment methods of the body composition in overweight and sedentary obese women submitted to two months of circuit training (CIRC) or Jogging (JOGG) and to associate the physical performance to the muscular index calculated using two methods. METHODS: Groups: CIRC, n = 14, body mass index (BDI, kg/m²) = 32 ± 8 (mean ± SD; age = 34 ± 10 years; and JOGG, n = 12, BMI = 30 ± 3; age = 38 ± 11. Training: 60 min. x 3d/week in the first month, and 60 min. x 4d/week in the second month. Assessment of the body composition: anthropometry^(1,2), bio-impedance⁽³⁾, and somatotype⁽⁴⁾. It was performed one maximal repetition test (1-MR) to the bench press, leg press and low-seated rowing exercises. RESULTS: The mass, the BMI, the body fat percentage by the anthropometry and bio-impedance, and the endomorphy were significantly reduced in both groups. The mesomorphy had a decrease, and the ectomorphy increased in the JOGG. The bio-impedance slim and muscular mass did not change in both groups. The muscular circumference of the arm (MCA) had a significant increase in the CIRC. The result of the bio-impedance fat percentage and the anthropometry were the same and significantly correlated. The endomorphy was significantly correlated to the anthropometry fat percentage, and to the mesomorphy to the slim mass anthropometry. The ectomorphy was not correlated to the slim mass of the anthropometry. CONCLUSION: The somatotype had a good result to assess the phenotypical changes in obese women submitted to the training. Nevertheless, the endomorphy presented the best concordance, and the ectomorphy had the worst one compared to other methods. The results of the somatotype suggest that the CIRC attained the best result into this group. The bio-impedance and the anthropometry produced similar results to assess the body composition.
