MORENO, Marlene Aparecida et al. Adaptações do sistema respiratório referentes à função pulmonar em resposta a um programa de alongamento muscular pelo método de Reeducação Postural Global. Fisioter. Pesqui. [online]. 2009, vol.16, n.1, pp.11-15. ISSN 1809-2950.

The aim of this study was to analyse the respiratory system adaptations concerning pulmonary function in response to stretching the respiratory muscle chain, by means of Global Posture Reeducation (GPR). Twenty sedentary young men with similar anthropometry and no history of musculoskeletal or cardiorespiratory disease were randomly divided into two groups of ten each: control group (CG), who did no stretching, and treated group (TG), submitted to GPR. Stretching was carried out twice a week for 8 weeks, in a total of 16 sessions. The two groups were submitted to pulmonary function tests to assess slow vital capacity, forced vital capacity and maximal voluntary ventilation, before and after the intervention period. The initial values of all spirometric variables measured in CG volunteers showed no statistically significant differences when compared to those of the final evaluation (p>0.05), whereas in TG all values increased after intervention (p<0.05). The GPR respiratory muscle chain stretching protocol thus proved efficient to promote an increase in spirometric variables, suggesting that it may be used as an auxiliary resource in respiratory physical therapy.
