Cinemática do complexo toracoabdominal de homens e mulheres obesas em repouso e após simulação de AVD: uso da Pletismografia Optoeletrônica e teste de AVD de Glittre

Abstract

Obesity affects the respiratory system and functional performance by various mechanisms. Although the rib cage and abdomen move in unity, each compartment has independent movement. Healthy men and women of different age groups showed symmetry between chest and abdomen movements. Objective: Analysis of thoracoabdominal complex kinematics of obese men and women at rest and after ADL simulation: Use of Optoelectronic Plethysmography (POE) and Glittre ADL test.Methods: This is a cross-sectional study of 38 volunteers (18M / 20F), aged between 18 and 40 years, classified by the World Health Organization (WHO) as obese (BMI ≥30 kg \ m²), submitted to evaluations. of: Glittre ADL test, thoracoabdominal kinematics, by POE, at rest and after ADL simulation. Results: In males, the percentage contribution (%) of the different compartments of the thoracoabdominal complex during quiet breathing was higher in ABD, without changes between RCP and RCA, while in females, the contribution of RCA was lower, without changes between PRC and ABD. When comparing the contributions between sex, men had a higher contribution from the ABD compartment, while women had a higher contribution in the RCP compartment. After performing the Glittre ADL test, in both sexes, significant changes occurred in the contribution pattern of all compartments. In men, there was an increase in the contribution of RCP and RCA, with consequent reduction in ABD, while in women the contribution was higher in the RCA and ABD, with consequent reduction of RCP. In the correlation between the degree of obesity and the percentage contribution of the different thoracoabdominal compartments, in both genders, BMI levels 2 and 3 showed significant correlations with the percentage contribution of the ABD compartment. Conclusion:The behavior of thoracoabdominal kinematics acts differently among obese men and women and changes significantly after simulation of an ADL. The higher the BMI, the greater the percentage of abdominal compartment (ABD) contribution, and that obesity is associated with reduced functional performance during daily living activities and this decline occurs similarly among obese men and women.
