Previous issue date: 2017-02-24 / Os indiv?duos asm?ticos apresentam preju?zos tanto da fun??o muscular respirat?ria, devido as modifica??es da mec?nica ventilat?ria, quanto perif?rica, ocasionada pela altera??es metab?licas com redu??o da capacidade oxidativa. Tais condi??es resulta em aumento da dispneia e fadiga. Como esses m?sculos s?o ativados durante atividades cotidianas nessa popula??o ? indeterminado. O presente trabalho teve como objetivo analisar o comportamento da atividade el?trica dos m?sculos respirat?rios e perif?ricos e o desempenho nos testes de exerc?cio: Incremental Shuttle Walking Test (ISWT) e o teste Glittre-AVD, em indiv?duos asm?ticos versus indiv?duos n?o-asm?ticos. Participaram indiv?duos com diagn?stico cl?nico de asma, de ambos os sexos, com idade entre 20 e 50 anos, doen?a controlada, ?ndice de massa corporal (IMC) abaixo de 30 kg/m?, n?o-fumantes e indiv?duos n?o asm?ticos pareados por idade, sexo e IMC. Ap?s avalia??o inicial, todos os participantes foram submetidos a dois testes de exerc?cio: ISWT e o teste Glittre-AVD. Durante os testes, foram avaliados os m?sculos esternocleidomast?ide (ECOM), escaleno (ESC), reto abdominal (RA) e reto femoral (RF) para o ISWT e ESC, RA, RF e o m?sculo deltoide m?dio (DM) para Glittre-AVD, atrav?s da eletromiografia de superf?cie (EMGs). A an?lise estat?stica foi feita pelo programa estat?stico GraphPad Prism vers?o 6.0, para p<0,05. Foi utilizado o teste Shapiro-Wilk para normalidade das vari?veis estudadas. O teste Mann-Whitney para an?lise intergrupo das vari?veis cardiovasculares, respirat?rias e Borg (dispneia e fadiga). Para an?lise intergrupo da atividade el?trica dos m?sculos estudados, foi utilizado o teste ?t? n?o ? pareado, para o ISWT, e teste Mann-Whitney para o Glittre-AVD. Dezesseis pacientes asm?ticos compuseram o Grupo Asma (GA) e 10 sujeitos n?o-asm?ticos o Grupo Controle (GC). A amostra do GA vs GC apresentaram: idadeanos: 35,31? 11,31 vs 34,70?15,61, IMCkg/m2: 24,49?4,15 vs 22,34?1,797, VEF1%: 78,74?17,41 vs 90,84?7,74 (p<0,01), VEF1/CVF%predito: 84,46?12,53 vs 100,6?8,43 (p<0,01), respectivamente. N?o houve diferen?a na sintomatologia relatada de dispneia e fadiga em membros inferiores, vari?veis cardiorrespirat?rias e capacidade inspirat?ria, entre os grupos, ao final de cada teste. Em rela??o ao desempenho no ISWT, o GA percorreu uma dist?ncia menor que o GC (p<0,05). Para o teste Glittre-AVD, o GA executou o teste com quase 1 minuto a mais comparada ao GC (p<0,05). A an?lise da EMGs durante o ISWT demonstrou aumento da atividade el?trica dos m?sculos avaliados de maneira coordenada e similar, em ambos os grupos, com diferen?a significativamente maior apenas para ECOM do GC em 100% do teste (p<0,05). No Glittre-AVD n?o houve diferen?a de ativa??o para os m?sculos ESC e DM. Os m?sculos RA e RF exibiram uma maior ativa??o no GC, por?m sem diferen?a significativa. Nossos resultados sugerem que durante os testes de exerc?cio ISWT e Glittre-AVD, os pacientes asm?ticos apresentam atividade eletromiogr?fica coordenada e similar aos indiv?duos saud?veis, entretanto com menor desempenho em ambos os testes. / Asthmatic individuals exhibit impairment both respiratory muscle function, due to changes in ventilatory mechanics, and peripheral, caused by metabolic alterations with reduction of oxidative capacity. Such conditions result in increased dyspnea and fatigue. How these muscles are activated during daily activities in this population is undetermined. Thus, the goal of this study was to analyze the behavior of the electrical activity of respiratory and peripheral muscles and performance in exercise tests: Incremental Shuttle Walking Test (ISWT) and Glitter-ADL test in asthmatic subjects comparing with non asthmatic subjects. Participated patients with clinical diagnosis of asthma, of both gender, aged between 20 and 50 years, controlled disease, body mass index (BMI) below 30 kg / m?, non smokers and non asthmatic subjects matched by age, sex and BMI. After initial assessment, all participants were submitted to two exercise tests: ISWT and the Glitter-ADL test. During the tests, were evaluated the sternocleidomastoid (ECOM), scalene (ESC), rectus abdominis (RA) and rectus femoris (RF) muscles for the ISWT and ESC, RA, RF and the middle deltoid (DM) muscle for the Glitter-ADL test, through surface electromyography (EMGs). The statistical analysis was done by the statistical program GraphPad Prism version 6.0, for p <0.05. The Shapiro-Wilk test was used for the normality of the studied variables and Mann-Whitney for intergroup analysis of cardiovascular, respiratory and Borg variables (dyspnea and fatigue). For intergroup analysis of the electrical activity of the muscles studied it was used the unpaired T test for the ISWT and Mann-Whitney test for the Glitter-ADL test. Sixteen asthmatic patients composed the Asthma Group (GA) and ten non-asthatic subjects Control Group (CG). The GA vs GC sample showed: age: 35.31 ? 11.31 vs 34.70 ? 15.61, IMC kg / m2: 24.49 ? 4.15 vs 22.34 ? 1.797, FEV1%: 78.74 ? 17.41 vs 90.84 ? 7.74 (p <0.01), FEV 1 / FVC% predicted: 84.46 ? 12.53 vs 100.6 ? 8.43 (p <0.01), respectively . There was no difference in the reported symptomatology of dyspnea and fatigue in lower limbs, cardiorespiratory variables and inspiratory capacity, between the groups, at the end of each test. Regarding the ISWT performance, the GA walked a distance shorter than the GC (p <0.05). For the Glitter-ADL test, GA performed the test with almost 1 minute more compared to GC (p <0.05). The EMG analysis during the ISWT showed an increase in the electrical activity of the muscles evaluated in a coordinated and similar way, in both groups, with a significant difference only for ECOM of GC in 100% of the test (p <0.05). In Glitter-ADL test, there was no difference in activation for the ESC and DM muscles. The RA and RF muscles showed greater activation in the CG, but no significant difference. Our results suggest that during the ISWT and Glitter-ADL exercise tests, asthmatic patients exhibit coordinated electromyographic activity and similar to healthy individuals, however with lower performances in both tests.
