Abstract: The strength of the respiratory muscles can be evaluated from static measurements (maximal inspiratory and expiratory pressures, MIP and MEP) or inferred from dynamic maneuvers (maximal voluntary ventilation, MVV). Although these data could be suitable for a number of clinical and research applications, no previous studies have provided reference values for such tests using a healthy, randomly selected sample of the adult Brazilian population. With this main purpose, we prospectively evaluated 100 non-smoking … Show more

“…JR's baseline MEPs (56 cm H 2 O) were less than half of expected for his age and gender (115.5+/−21.0 cm H 2 O) 15. EMST was noted to improve JR's MEPs by 52 cm H 2 O to within the normal range thereby increasing the respiratory reserve between expiratory capability and demand.…”

“…Segundo Neder et al, 3 os idosos têm regressão na massa muscular do diafragma e da musculatura acessória da respiração, e também apresentam menor resposta desses músculos a um mesmo nível de estimulação neural.…”

“…3,4 Observamse declínio da capacidade vital forçada, volume expiratório forçado no primeiro segundo e fluxo expiratório forçado, bem como aumento na capacidade residual funcional e volume de reserva expiratório, que se relacionam com a redução no recolhimento elástico pulmonar e a diminuição da complacência da caixa torácica. 5 Essas alterações são responsáveis pela redução da força muscular respiratória, prejudicando não só a função de bomba ventilatória como também as funções não ventilatórias do sistema respiratório.…”
