Objectives: To evaluate the influence of obesity in the movement of thoracoabdominal complex at rest and during maximal voluntary ventilation (MVV), and the contribution between the different compartments of this complex and the volume changes of chest wall between obese and non-obese patients. Materials and Methods: We studied 16 patients divided into two groups: the obese group (n = 8) and group non-obese (n = 8). The two groups were homogeneous in terms of spirometric characteristics (FVC mean: 4.97 ± 0.6 L - 92.91 ± 10.17% predicted, and 4.52 ± 0.6 L - 93.59 ± 8.05%), age 25.6 ± 5.0 and 26.8 ± 4.9 years, BMI 24.93 ± 3.0 and 39.18 ± 4.3 kg/m2 in non-obese and obese respectively. All subjects performed breathing calm and slow and maneuver MVV, during registration for optoelectronic plethysmography. Statistical analysis: we used the unpaired t test and Mann-Whitney. Results: Obese individuals had a lower percentage contribution of the rib cage abdominal (RCa) during breathing at rest and VVM. The variation of end expiratory (EELV) and end inspiratory (EILV) lung volumes were lower in obese subjects. It has been found asynchrony and higher distortion between compartments of thoracoabdominal complex in obese subjects when compared to non-obese. Conclusions: Central obesity impairs the ventilation lung, reducing to adaptation efforts and increasing the ventilatory work. Contextualização: A obesidade pode afetar o sistema respiratório, causando alterações na mecânica ventilatória, nos volumes e fluxos pulmonares. Objetivos: Avaliar a influência da obesidade no movimento do complexo tóraco-abdominal durante o repouso e durante a ventilação voluntária máxima (VVM), assim como a contribuição entre os diferentes compartimentos desse complexo e as variações de volume da parede torácica e entre obesos e não obesos. Materiais e Métodos: Foram avaliados 16 indivíduos divididos em dois grupos: grupo de obesos (n = 8) e grupo de eutróficos (n = 8). Os dois grupos foram homogêneos quanto às características espirométricas (média de CVF: 4,97 ± 0,6 L – 92,91 ± 10,17 % do predito, e 4,52 ± 0,6 L – 93,59 ± 8,05 %), idade 25,6 ± 5,0 e 26,8 ± 4,9 anos, IMC 24,93 ± 3,0 e 39,18 ± 4,3 kg/m2, em eutróficos e obesos respectivamente. Todos os sujeitos realizaram respiração calma e lenta e a manobra de Ventilação voluntária máxima, durante o registro por pletismografia optoeletrônica. Para análise estatística, foram utilizados os testes t não pareado e de Mann-Whitney. Resultados: Os indivíduos obesos apresentaram menor contribuição percentual da caixa torácica abdominal (RCa) durante a respiração em repouso e na VVM. A variação dos volumes pulmonares expiratório (EELV) e inspiratório finais (EILV) foram menores nos sujeitos obesos. Foram constatados maiores assincronia e distorção entre os compartimentos do complexo tóraco-abdominal nos obesos, quando comparados aos eutróficos. Conclusões: A obesidade central interfere negativamente na ventilação pulmonar, reduzindo a adaptação aos esforços e incrementando o trabalho ventilatório.
