“…This result suggests an explanation for the fact that the MRP of private school students were significantly higher than those of public school students, since most children who practiced some kind of physical activity studied in private schools. When assessing MRP in healthy adults, Simões et al (1) found that the sample did not reach the values predicted for the age group assessed. According to these authors, the MRPs obtained were lower than the predicted normal values because the sample was composed only of sedentary individuals.…”

“…Respiratory muscle strength may be influenced by factors such as age, sex, weight, height, physical activity level and ethnicity (1,9) . Studies carried out in order to provide normal values for MRP in children showed, besides the existence of differences between the sexes for these measurements, a correlation of MRPs with weight (5,10) , age (5,(10)(11)(12)(13)(14) and height (10)(11)(12) .…”

OBJETIVO: Comparar os valores obtidos das pressões inspiratórias máximas (PImáx) e pressões expiratórias máximas (PEmáx) entre estudantes das redes pública e privada de ensino. MÉTODOS: Estudo observacional do tipo descritivo transversal. Foram avaliadas 144 crianças nas duas redes de ensino. As pressões respiratórias máximas foram mensuradas com o MVD300 (Globalmed®). Aplicou-se o teste t de Student não pareado para comparar as médias das variáveis estudadas e o teste do qui-quadrado para comparar a frequência de crianças que realizavam ou não atividade física. RESULTADOS: Os alunos das escolas privadas e públicas apresentaram, respectivamente, média de PImáx 77,0±21,5 e 65,7±18,7cmH2O (p=0,002) e PEmáx 90,1±22,5 e 79,4±19,0cmH2O (p=0,005). Os meninos, das escolas privadas e públicas, apresentaram médias de PImáx 85,0±20,8 e 74,4±17,1cmH2O (p=0,051) e PEmáx 98,5±2,5 e 89,2±16,3cmH2O (p=0,103), respectivamente. As meninas, das escolas privadas e públicas, apresentaram médias de PImáx 70,0±19,8 e 60,2±17,8cmH2O (p=0,027) e PEmáx 82,6±20,0 e 73,2±18,1cmH2O (p=0,035), respectivamente. Aproximadamente 40% dos alunos da rede pública e 95% dos alunos da rede privada realizavam atividade física. As crianças que realizavam ou não atividade física apresentaram PImáx 76,0±20,7 e 63,2±20,0cmH2O (p=0,002) e PEmáx 89±21,6 e 77,4±20,5cmH2O (p=0,006), respectivamente. CONCLUSÕES: A força muscular respiratória dos alunos da rede privada foi significativamente superior à dos alunos da rede pública, especialmente entre as meninas. Possivelmente, essa diferença esteja relacionada à prática de atividade física, mais frequentemente observada nas escolas privadas.

“…Los valor obtenidos fueron significativamente mayores en hombres sobre las mujeres, asimismo la PEM fue mayor a la PIM. Este comportamiento concuerda con lo reportado por Morales et al (1997), Simões et al (2010) y Araújo et al (2012) y se debe a la mayor talla, peso y masa muscular en el sexo masculino.…”

MUÑOZ, C. R.; BECERRA, M. S. & PACHECO, V. A.Influencia del polimorfismo inserción/deleción (rs4646994) del gen de la enzima convertidora de angiotensina en la presión inspiratoria y espiratoria máxima de jóvenes chilenos sedentarios. Int. J. Morphol., 35(4):1254Morphol., 35(4): -1260Morphol., 35(4): , 2017. RESUMEN:La expresión de los genes puede impactar sobre el rendimiento muscular. En este aspecto el polimorfismo del gen de la Enzima Convertidora de Angiotensina (ECA), dependiendo de su inserción (Ins) o deleción (Del) puede potenciar diferentes cualidades musculares. Del mismo modo, si consideramos la ventilación como un proceso vital, sería relevante investigar si existe una influencia de este polimorfismo sobre los músculos que llevan a cabo tan importante función. El objetivo de este trabajo consistió en determinar el rendimiento muscular inspiratorio y espiratorio según alelos y polimorfismos del gen de la ECA. Se sometió a 83 sujetos (18 a 35 años), 46 hombres y 37 mujeres, a evaluaciones de capacidad vital forzada (CVF), presión inspiratoria máxima y presión espiratoria máxima (PIM-PEM). Posterior a esto, la genotipificación fue realizada por polimerase chain reaction (PCR) y electroforesis en gel de agarosa. Las variables fueron sometidas al análisis estadístico correspondiente según su distribución paramétrica, el nivel de significancia establecido fue un p<0,05. La distribución genotípica fue: Ins/Ins: 28 %, Ins/Del: 62 % y Del/Del: 19 %. Las mujeres homocigoto Ins, presentaron mayor PIM y PEM en modelos por genotipos (p=0,043; p=0,0001 respectivamente) y por dominancia (p=0,019; p=0,0008 respectivamente). La distribución genotípica y frecuencia alélica fue similar a la descrita anteriormente en población chilena. Además, las mujeres portadoras del alelo Ins, presentaron mayor PIM y PEM.PALABRAS CLAVE: Presión inspiratoria máxima; Presión espiratoria máxima; Enzima convertidora de angiotensina.

Objective: This study investigated the concurrent validity, inter and intra-reliability of manual evaluation in Asthma patients. Methods: Twenty six asthma patients were assessed. Maximal respiratory muscle strength (Mrms) was tested by inspiratory and expiratory pressure (MIP and MEP, respectively) trough manovacuometer. In addition, Mrms of diaphragm (anterior and posterior), Intercostals (lower and upper portion) and Rectus abdominal were obtained manually, according to Medical Research Council (MRC) scale. Two independents evaluators, previously trained, made both measurements. Results: Reproducibility of Mrms intra-evaluators: anterior diaphragm (ICCs, 0.79 and 0.67); Posterior portion of the diaphragm (ICCs, 0.43 and 0.51); Upper intercostals (ICCs, 0.47 and 0.40); Lower intercostals (ICCs, 0.81 and 0.51) and rectus abdominal (ICCs, 1.0). Inter-reproducibility of anterior diaphragm was low to moderate, while intercostals (upper and lower portion) was relatively low. However, rectus abdominal presented high reproducibility reflecting in almost perfect agreement. In addition, we found positive correlations between MIP versus Lower Intercostals (r = .60, p = .007) and MEP versus rectus abdominal (r = .41, p = .04). Conclusion: In asthmatic patients, manual evaluation of the respiratory muscles is reliable. In addition, maximal respiratory pressures using manometer assessment were related to manual evaluation, in special to diaphragm and rectus abdominal muscles.
