“…No changes were observed in the spirometric values of our sample; however, a literature review carried out by Veron et al 26 contrasts our findings by suggesting that disorders resulting from oral breathing contributes to muscle imbalance and poorer lung function. In another study, Trevisan et al 27 reported that mouth-breathing adults exhibit a reduction in diaphragmatic amplitude compared to nosebreathing adults, a result that is consistent with pulmonary restriction.…”

BACKGROUND: We sought to evaluate the acute effects of different inspiratory loads using nasal and oral interfaces on the volumes of the chest wall and its compartments, breathing pattern, and respiratory muscle activation in children with mouth-breathing syndrome. METHODS: Children with mouth-breathing syndrome were randomized into 2 groups, one with an inspiratory load intensity 20% of maximum inspiratory pressure (n 5 14), and the other with an inspiratory load intensity 40% of maximum inspiratory pressure (n 5 15). The chest wall volumes and electromyography of sternocleidomastoid, rectus abdominis, scalene, and internal intercostal muscles were used to analyze respiration against the 2 load intensities and using 2 interfaces (ie, nasal and oral). RESULTS: A total of 72 children with mouth-breathing syndrome were recruited, and 29 were evaluated in this study. The use of inspiratory load promoted improvement in the components of the breathing pattern: breathing frequency (P 5 .039), inspiratory time (P 5 .03), and total respiratory time (P 5 .043); and increases in tidal volume (P < .001), end-inspiratory volume (P < .001), and electrical activity of scalene muscles and sternocleidomastoid muscles (P < .001) when compared to quiet breathing. The load imposed via a nasal interface versus an oral interface provided an increase in tidal volume (P 5 .030), endinspiratory volume (P 5 .02), and electrical activity of scalene muscles (P < .001) and sternocleidomastoid muscles (P 5 .02). CONCLUSIONS: The use of acute inspiratory loads improved the breathing pattern and increased lung volume and electrical activity of inspiratory muscles. This work brings new perspective to the investigation of using nasal interfaces during the application of inspiratory loads. The nasal interface was more effective compared to the oral interface commonly used in clinical practice.

“…O inadequado desempenho da musculatura envolvida na respiração pode levar à diminuição da capacidade vital e do fornecimento de ar em nível glótico (Goffi-Fynn & Carroll, 2013;Traser et al, 2017). A região lombo-pélvica constitui o centro de força do corpo (CFC), uma cinta muscular que estabiliza a coluna e o tronco (Valente et al, 2015;Frigo & Braz, 2016;Santana, Prina, Albuquerque, Carvalho, & Caruso, 2016;Veron, Antunes, Milanesi, & Correa, 2016) e também auxilia a formação de pressão expiratória positiva para a fonação com a ativação conjunta dos músculos abdominais, do tronco e do assoalho pélvico (Cielo, Gonçalves, Lima, & Christmann, 2012;Lima, Cielo, & Christmann, 2016;Nunes, 2018;Pinto, Saraiva, Camatti, & Luz, 2018). O recrutamento da musculatura do CFC, a favor do trabalho respiratório (Valente et al, 2015;Frigo & Braz, 2016), permite melhora da atuação do diafragma e maior mobilidade da caixa torácica, podendo gerar maior fluxo aéreo expiratório e melhor qualidade da voz (Siqueira, Alencar, Oliveira, & Leite, 2014;Porolnik, Braz, Padilha, & Seidel, 2015).…”

The adequate respiratory support ensures resonance, projection, focus, stability, and better vocal quality. The aim of this study was to verify the relationship between the activation of the core musculature and the spectrographic acoustic vocal characteristics in a group of adult women. This is a cross-sectional, observational, analytical, and quantitative study with ten women 19 to 28 years old, without vocal complaints, and without laryngeal disorders. Spectrographic vocal analysis, maximum expiratory pressure measurement, and evaluation of the multifidus, transverse and perineum muscles were performed. The data were analyzed using the Spearman Correlation Test at 5 %. The results showed significant positive correlation between the maximum expiratory pressure and the definition of the second formant; between the activation of the perineal muscle and the regularity of the spectrographic tracing. And showed significant negative correlation between the activation of the multifidus muscles and the width of the second formant. It was concluded that the more activated the perineal musculature, the greater the regularity of the spectrographic tracing; the higher the maximum expiratory pressure, the greater the definition of the second formant; and the greater the activation of the multifidus muscles, the smaller the bandwidth of the second formant. Such findings demonstrate the role of the core strength in the vocal quality. A relationship was established among the maximum expiratory pressure, the activation of the core muscles, and the spectrographic vocal characteristics.

“…Em indivíduos saudáveis, especificamente em crianças, como o caso da amostra estudada, é evidente que alterações posturais, hábitos de vida tecnológicos e pouca atividade física podem gerar comprometimentos respiratórios, ainda que sejam indivíduos considerados hígidos 3 . Dentre a principal alteração, encontra-se a respiração oral.…”

Introdução: Objetivo: analisar a relação entre força muscular respiratória(FMR) e capacidade de atingir valores preditos na manobra espirométrica de capacidade vital lenta(CVL)em crianças em idade escolar. Método: pesquisa observacional transversal, incluiu crianças saudáveis entre 6 e 12 anos, cuja higidez controlou-se por meio de espirometria normal(Pneumatógrafo Jaeger-Master Scope IOS®), segundo American Thoracic Society (2005) e questionários de saúde (ISAAC e histórico de saúde). As crianças foram divididas em GCVL: aquelas que atingiram 80% na manobra de CVL;e como GCON: as que não atingiram este valor. As pressões máximas inspiratória (PI max ) e expiratória (PE max ) foram obtidas por meio de manovacuometria (MVD 300 Globalmed®). Após verificação da normalidade dos dados, aplicouse o teste de Spearman para análise da relação entre FMR com parâmetros de CVL. Os dados de PI max e PE max foram comparados entre os grupos, com o teste de Mann-Whitney. Adotou-se nível de significância de 5% (p<0,05). Resultados: participaram 83 crianças com média de idade de 8,54 ±1,95anos, sendo 44 no GCVL (25 meninas). Este grupo apresentou maiores valores absolutos e em percentual do predito (%)de capacidade inspiratória (CI), volume de reserva expiratório (VRE) e FMR. Houve relação entre % de CI e VRE com PE max . No GCON, (39 crianças /20 meninas) houve relação entre valores absolutos de CVL, CI, VRE e PI MAX e destes dois primeiros parâmetros e da % de CI com a PE MAX .Conclusões: houve relação entre a FMR e a capacidade de atingir 80% do predito na CVL, sendo que essa porcentagem foi alcançada pelas crianças com valores superiores de FMR.
