RESUMO
Introdução:
O processo de envelhecimento promove alterações no sistema cardiorrespiratório, aumentando a prevalência de hipertensão arterial e reduzindo a força da musculatura respiratória.Objetivos:
Avaliar os efeitos de um programa de treinamento muscular inspiratório domiciliar (TMID) sobre a função pulmonar, força muscular respiratória e distância percorrida no teste de caminhada de 6 minutos (TC6min) em idosas hipertensas.Métodos:
Dezesseis mulheres com diagnóstico de hipertensão arterial foram divididas em dois grupos. Oito participaram do grupo intervenção (GI) e foram submetidas ao TMID durante seis semanas, e as demais compuseram o grupo controle (GC).Resultados:
Ao final do TMID, constatou-se aumento da PImáx, -47±13 cmH₂0 para -92±32 cmH₂0 (p<0,001), e PEmáx, 45±6 cmH₂0 para 84±24 cmH₂0 (p<0,001), do Pico de Fluxo Expiratório (PFE), 211,6±60 L/min para 248,8±58 L/min (p=0,004).Conclusões:
O TMID realizado diariamente durante seis semanas proporciona melhora na força muscular respiratória e no pico de fluxo expiratório em idosas hipertensas.ABSTRACT
Introduction:
The aging process brings changes to the cardiovascular system, increasing the prevalence of hypertension and reducing the respiratory muscle strength.Objectives:
To assess the effects of a home-based inspiratory muscle training (IMT) on pulmonary function, respiratory muscle strength and distance walked in 6-minute walk test (6MWT) in hypertensive elderly women.Methods:
Sixteen women with clinical diagnosis of hypertension were divided into two groups. Eight participated in the intervention group (IG) and were subjected to the home-based IMT during six weeks, and the others composed the control group (CG).Results:
At the end of the IMT, we found out the increase of maximal inspiratory pressure (MIP), -47±13 cmH₂0 to -92±32 cmH₂0 (p<0.001), the maximal expiratory pressure (MEP), 45±6 cmH₂0 to 84±24 cmH₂0 (p<0.001), and the peak expiratory flow (PEF), 211.6±60 l/min to 248.8±58 l/min (p=0.004).Conclusions:
The home-based IMT daily performed for six weeks improves the respiratory muscle strength and in the PEF in hypertensive elderly women.
