Abstract:O hábito de fumar pode reduzir a capacidade aeróbica, aumentar a resistência ao fluxo aéreo e afetar a função dos músculos respiratórios. O objetivo deste estudo foi comparar os efeitos do Treinamento Muscular Inspiratório (TMI) entre dois grupos: tabagistas e não tabagistas. Participaram 44 voluntários universitários, divididos em dois grupos: tabagistas (GT), composto por 20 indivíduos (25,60±7,01 anos) e não tabagistas, constituindo o Grupo Controle (GC), composto por 24 voluntários (24,08±7,52 anos).

“…4 Inspiratory muscle training induced a reduction in fasting glucose levels and improved the secretory capacity of pancreatic β cells. These results support a previous study in which inspiratory muscle training effectively improved insulin resistance, where the respiratory training may strengthen the skeletal musculature improving diaphragmatic respiratory capacity and increasing mobilization of GLUT4 with subsequent increase in glucose uptake and a reduction in HOMA-IR parameters.…”

Fasting hyperglycemia is often observed in the older adult population, showing that after the age of 50, fasting blood glucose levels increase by 0.06 mmol/decade. Therefore, many authors embrace the hypothesis that with aging and progressive fasting blood sugar disorders can lead to glucose intolerance and type 2 diabetes.1 Fasting hyperglycemia (100-125 mg/dl or 5.6 to 6.9 mmol/L) is defined as an intermediate state type 2 diabetes and normal levels. Older people are often faced with limitations when it comes to regular physical activity, in these cases, inspiratory muscle training with Threshold® can be an effective alternative to overcome these barriers. A study carried out in older adult with insulin resistance revealed significant improvements after inspiratory training with the Threshold device. These results support the use of intervention in fasting hyperglycemia.
3For this research, 38 older adults over 60 years with fasting hyperglycemia from the Center for the Study of Aging at UNIFESP were divided into 2 groups: a control group (n = 20) that trained with the Threshold device with minimal load and an experimental group (n = 18) that performed respiratory muscular training during the first session of each week at inspiratory loads of 40% of the maximal inspiratory pressure (PImax). The training program was performed over 8 weeks in 30-minute daily sessions.Data were analyzed and the comparison between groups was done using SPSS version 19.0, and means were analyzed using ANOVA.The 2 groups were homogeneous, showing a mean age of 74.10 years, BMI of 27 kg/m 2 . After intervention, the individuals presented a significant increase of the inspiratory and expiratory pressure values, maximum threshold pressure sustained, and charging times in both groups. The laboratory evaluation results showed the interaction effects for blood glucose variable and HOMA-β. Others variables presented no significant differences and remained within the normal range (see Table 1).Intervention increased inspiratory and expiratory pressure values, and the result was expected to the extent that the recruitment of motor units promoted increased muscle strength in muscles working in the thoracoabdominal region. 4 Inspiratory muscle training induced a reduction in fasting glucose levels and improved the secretory capacity of pancreatic β cells. These results support a previous study in which inspiratory muscle training effectively improved insulin resistance, where the respiratory training may strengthen the skeletal musculature improving diaphragmatic respiratory capacity and increasing mobilization of GLUT4 with subsequent increase in glucose uptake and a reduction in HOMA-IR parameters.3 Another hypothesis is that the reduction of impaired fasting glucose in the older adult population may be due to an improvement in mitochondrial oxidative metabolism and a decreased reactive oxygen species (ROS) production, increased antioxidant capacity, or increased mitochondrial density.5 Moreover, the mitochondrial theory of aging proposes th...

“…A força muscular inspiratória reduzida semelhante a apresentada pelo paciente deste relato de caso, já tinha sido evidenciado em um estudo de Ohara e outros, (8) em que mulheres com AF apresentaram valores de PI máx abaixo do previsto no grupo avaliado, justificando assim a realização de TMI para ganho de força e endurance da musculatura inspiratória para este grupo de indivíduos [8][9] . Nesse relato de caso, o indivíduo apresentava um valor de força de aproximadamente 40% do valor predito para equação brasileira de referência, (10) o que confirma a presença de fraqueza muscular inspiratória.…”
ResumoObjetivo: Este artigo relata o caso de um indivíduo adulto com diagnóstico de anemia falciforme (AF) desde a adolescência, com histórico de várias internações hospitalares ao longo dos anos e com relato de dispnéia durante algumas atividades de vida diária. Descrição do caso: Na avaliação inicial foram obtidos os valores de pressão inspiratória máxima (PImáx) e da capacidade vital (CV) através do aparelho POWERbreathe® digital modelo K5 (POWERbreathe International Limited, Londres, Inglaterra), e do índice basal de dispnéia (BDI) durante as atividades de vida diária. Após a identificação da fraqueza muscular inspiratória (PImáx ≤60% do predito), foi sugerido a realização do treinamento muscular inspiratório (TMI) com um dispositivo resistor inspiratório de carga linear. O ajuste inicial foi com uma carga de 65% da PImáx, durante 6 semanas, de forma diária, com 30 incursões realizadas duas vezes ao dia. No 21º e 42º dia foram realizadas novas avaliações da PImáx e CV, sendo reavaliado o BDI no 42º dia. No 21º dia do programa foi verificado uma elevação de 13,8% na PImáx e 82,3% na CV. Já no 42º dia, foi observado mais um ganho na PImáx sem alteração dos valores da CV. Na análise do BDI foi verificado um incremento de 7 para 12 pontos (71,4%), o que caracteriza um paciente sem dispnéia ao realizar as atividades propostas pelo instrumento. Conclusão: Identificou-se uma melhora da força muscular inspiratória e da dispnéia nas atividades diárias após o programa de TMI no presente relato de caso.Palavras-chave: Anemia Falciforme; Função pulmonar; Treinamento muscular inspiratório.• Artigo submetido para avaliação em 13/08/2015 e aceito para publicação em 14/09/2015 •
“…O tabagismo pode limitar a capacidade aeróbica, ampliar a resistência ao fluxo aéreo e influenciar na função dos músculos respiratórios 4 . Um parâmetro clínico de escolha para avaliar as disfunções, é a mensuração da Força Muscular Respiratória (FMR), que se compõe na obtenção das pressões respiratórias geradas desde esforços inspiratórios e expiratórios máximos assim como a medição do pico de Fluxo Expiratório (PFE) 5 .…”
Objetivo: avaliar os efeitos do tabagismo sobre a mecânica respiratória em adultos jovens. Métodos: esse estudo é delineado como pesquisa de campo, de abordagem quantitativa, descritiva e de natureza comparativa. A amostra do estudo foi composta por 18 participantes, escolhidos de acordo com os critérios pré-estabelecidos. Para coleta de dados, utilizou-se uma ficha de avaliação elaborada pelos pesquisadores, um manovacuômetro analógico para mensurar a força dos músculos respiratórios por meio da PImax e da PEmax e um Peak- Flow para medir o pico de fluxo expiratório. Resultados: a maioria dos participantes (n=12) 66,7% eram do gênero masculino e (n=6) 33,3% do gênero feminino. Dos (n=10) 55,6% tabagistas (n=6) 60% haviam iniciado fumo antes dos 18 anos. Segundo a escala de dependência de nicotina 30% do grupo apresentou grau elevado (n=3). Houve diferença estatisticamente significativa entre média de altura entre jovens com nível 1 em relação aqueles com nível 2 de dependência de nicotina (1,76 versus 1,67; p=0,01). Conclusão: O hábito apresenta efeitos deletérios, desenvolvendo uma dependência química e alterando a mecânica respiratória de adultos jovens.
