Avaliação do efeito da obesidade infantil e a do adolescente sobre as propriedades ventilométricas e força muscular do sistema respiratório

In this study, it was evaluated changes in pulmonary function in 50 individuals (obese children and adolescents) belonging to two groups: overweight and control, subjected to the test of pulmonary function through the analysis of the following parameters: slow vital capacity (SVL), peak expiratory flow (PEF) and respiratory muscle strength determined by maximum respiratory pressure (Pimax and Pemax). The SVC for the overweight group was 3.0 ± 0.7 liters, and the control group of 3.49 ± 0.9 liters (p = 0.0490). The PEF for the overweight group of 336 ± 107.4, and the control group of 386 ± 55.5 (p = 0.0404). It was concluded that there was a statistically significant change in pulmonary function in obese children and adolescents in relation to slow vital capacity and peak expiratory flow. No difference was observed for the assessment of maximal respiratory pressures
