Composição corporal e somatótipo de mulheres com sobrepeso e obesas pré e pós-treinamento em circuito ou caminhada

Abstract

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/m 2 ) = 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 bioimpedance 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.

Comparação de métodos de avaliação da gordura corporal total e sua distribuição

“…The present study found a high level of agreement between the two methods (bioimpedance and sum of skinfolds) used to assess body fat in kilograms (Kg). This has also been observed by other authors in studies conducted with women undergoing hemodialysis (r 2 =0.96) 36 (r 2 =0.87) 37 and with overweight and obese women practicing walking (r 2 =0.83) 19 . However, the results shown in this study differ from those found by Rodrigues-Barbosa et al 22 , who analyzed elderly women and did not find agreement (r 2 =0.25, p<0.05) between the methods studied (BIA and sum of skinfolds).…”

“…The majority of studies aimed at comparing total body fat assessment, using easily executed methods such as bioimpedance and the sum of skinfolds, were conducted with sportsmen and women or athletes 18,19 . In contrast, studies conducted with women from several age groups used different methods, including the most expensive ones 15,[20][21][22] .…”

Effects of a Program "Circuit Training" on Anthropometric Variable and Composition Body in Military Police

“…Thus, Fett et al [26], in a study of body composition and somatotype of overweight and obese women before and after circuit training or walking, observed greater action electromyography to analyze muscle groups of the lower rectus femoris, vastus medialis and lateral extensor knee. However, the gluteus maximus and rectus abdominis have changed in exercises with type board.…”

Comparação entre treinamento concorrente e corrida em piscina funda associados à orientação nutricional na perda de peso e composição corporal de indivíduos obesos

“…Do mesmo modo, Fett et al, 30 estudando apenas mulheres, encontraram redução significativa no peso, IMC e percentual de GC, sem alteração na MM, com dois tipos de exercício físico (resistido + aeróbico e somente aeróbico). Pavlou et al, 3 encontraram perda de peso e massa gorda, sem modificação na MM, em 72 obesos submetidos a uma intervenção com dieta + exercício de força + aeróbico.…”
