Previous issue date: 2012-02-28 / The reduction of physiological capacity present in the process of aging causes a marked decline in lung function. The exercise does promote several positive changes in the physical health of people and protect the cardiorespiratory function. The aim of this
study was to investigate the effects of a program of Pilates exercices on the strengh and electrical activity of respiratory muscles of elderly. This is a randomized, controlled clinical trial, evaluating 33 elderly aged 65 and 80 (70.88 ? 4.32), healthy, sedentary, without cognitive impairment and able the practice physical activity. The sample was divided into two groups, one experimental group with 16 elderly women who did Pilates
exercises and a control group (17) that was not submitted to the exercises, but received educational booklets on aging and health care. The elderly were evaluated initially and
after a period of three months, taking into account the Maximal Inspiratory Pressure (MIP) and Maximal Expiratory Pressure (MEP), obtained by Manovacuometry and intensity of EMG activity was measured using the values of Root Mean Square (RMS) for the diaphragm and rectus abdominis muscles, during the course of diaphragmatic breathing and MIP maneuver. Data were analyzed using SPSS version 17.0. For all tests, we used a significance level or p value < 0.05 and confidence interval 95%. RMS in diaphragm and rectus abdominis muscles in both tests increased, but the data were significant for the rectus abdominis during diaphragmatic breathing (p = 0.03) and the
diaphragm during the MIP maneuver (p = 0.01). There was no significant variation of the MIP and MEP. Pilates exercises were responsible for increasing the electrical activation
of the diaphragm and rectus abdominis muscles in a group of healthy elderly, but had no influence on changes in strength of respiratory muscles / A deteriora??o das fun??es fisiol?gicas est?o ligadas ao decl?nio do desempenho f?sico dos indiv?duos idosos. O exerc?cio promove altera??es positivas na sa?de, incluindo benef?cios cardiorrespirat?rios e aperfei?oamento do desempenho muscular e funcional, sendo fator de desacelera??o ou revers?o de preju?zos causados pelo envelhecimento. O M?todo Pilates ? muito utilizado na pr?tica cl?nica visando promover o reequil?brio
muscular com exerc?cios que d?o ?nfase ao powerhouse, exigindo que o indiv?duo mantenha a mente concentrada no n?cleo do corpo o tempo todo, atrav?s da respira??o. Apesar da grande popularidade do m?todo, h? car?ncia de estudos cient?ficos com aplica??o na Fisioterapia e com abordagens cinesiol?gica, fisiol?gica e/ou biomec?nica, em especial envolvendo os m?sculos respirat?rios. O objetivo foi investigar os efeitos de um programa de exerc?cios de Pilates sobre a for?a e atividade
el?trica dos m?sculos respirat?rios de idosas. Foram avaliadas 33 idosas saud?veis, sedent?rias, sem defici?ncia cognitiva e aptas ? pr?tica de exerc?cio f?sico e divididas em 2 grupos, Controle (n=17), que recebeu cartilhas educativas com orienta??es sobre
envelhecimento e sa?de e Experimental (n=16), que al?m das cartilhas, passou por um programa de 24 sess?es de exerc?cios de Mat Pilates. As idosas foram avaliadas inicialmente e ap?s um per?odo de tr?s meses, levando-se em conta as medidas das
press?es respirat?rias est?ticas m?ximas (PIm?x e PEm?x) e o RMS dos m?sculos diafragma e reto abdominal em dois testes diferentes. Foi utilizado o teste T de Student para compara??o entre os grupos e adotado um n?vel de signific?ncia p valor < 0,05 e intervalo de confian?a de 95%. A idade m?dia foi de 70,88 anos (?4,32). O RMS aumentou nos dois m?sculos avaliados em ambos os testes, por?m os dados foram significativos para o reto abdominal durante a respira??o diafragm?tica (p = 0,03) e para
o diafragma durante a manobra de PIm?x (p = 0,01). N?o houve varia??o significativa dos valores de for?a. Os exerc?cios de Pilates alteraram a atividade el?trica, mas n?o tiveram influ?ncia na for?a dos m?sculos respirat?rios num grupo de idosas saud?veis
