Resumo: Introduction – Inspiratory muscle training (IMT) emerges as an important intervention in people with COPD, but above all with a growing interest in the healthy population. However, there are not enough studies to prove if inspiratory muscle training is also reflected in the improvement of the aerobic capacity objectified in oxygen consumption (VO2). Therefore, more investigation is relevant to understand the real relationship between IMT and its results on healthy people. Thus, it was considered appropriate to carry out a research study on a healthy population that would allow assessing to what extent an inspiratory muscle training program induces changes in inspiratory muscle strength and aerobic capacity. Methods and analysis – The sample was based on healthy individuals (n=19) between 18 and 21 years old who perform the regular physical exercise (≥ 3 times a week or ≥ 4 hours per week). The aerobic capacity was estimated by the Ebbeling Test and inspiratory muscle strength was measured by the maximum inspiratory pressure (MIP) obtained by a specific dynamometer (MicroRPM®) at two different times (pre and post-workout). The above-mentioned sample was randomly divided into two groups (n=9 in the experimental group and n=10 in the control group). The experimental group (EG) was subjected to a high-intensity IMT (≥50% Pi, max) while the control group (CG) didn´t go through any intervention. The IMT was performed by PowerBreathe Classic® Level 1 and Level 2 which provides consistent and specific pressure for inspiratory muscle strength regardless of the individual's inspiratory flow. Conclusions – After the training, there was a 37% increase in EG PIM while the CG showed an improvement of 7%. In intergroup comparison, both groups increased significantly both MIP and VO2 (p<0.05). However, comparing both groups, the differences were significant for the PIM (p=0.000), but not for VO2. Further studies are required to assess in which conditions IMT produces changes in aerobic capacity.

No entanto, não existem estudos suficientes que comprovem se o treino dos músculos inspiratórios se traduz também numa melhoria da capacidade aeróbia objetivada no consumo de oxigénio (VO2). Assim, a relação entre o TMI e os seus resultados no indivíduo saudável carece de estudo que comprove os efeitos reais do treino. Considerou-se, pelo anteriormente exposto, pertinente a realização de um estudo de investigação na população saudável que permitisse avaliar em que medida um programa de TMI induz alterações na força muscular inspiratória e na capacidade aeróbia. Métodos e análise – A amostra foi constituída por indivíduos saudáveis (n=19) com idades compreendidas entre os 18 e 21 anos que realizam exercício físico regularmente (≥3 vezes por semana ou ≥4h por semana). A capacidade aeróbia foi estimada através do Teste de Ebbeling e a força dos músculos inspiratórios foi medida pela pressão inspiratória máxima (PIM) obtida num dinamómetro específico (MicroRPM®), em dois momentos distintos (pré e pós-treino). A referida amostra foi dividida aleatoriamente em dois grupos (n=9 no grupo experimental e n=10 no grupo de controlo). O grupo experimental (GE) foi submetido a um TMI de alta intensidade (≥50% Pi,máx), enquanto o grupo de controlo (GC) não foi sujeito a qualquer intervenção. O TMI foi realizado através do PowerBreathe Classic® Level 1 e Level 2, que fornece uma pressão consistente e específica para a força muscular inspiratória, independentemente do fluxo inspiratório do indivíduo. Conclusões – Após o treino verificou-se um aumento de 37% na PIM do GE, enquanto o GC apresentou uma melhoria de 7%. Na comparação intragrupos, ambos os grupos aumentaram significativamente tanto a PIM como o VO2  (p<0,05). Já na comparação intergrupos, a diferença foi significativa para a PIM (p=0,000), mas não para o VO2. Serão necessários mais estudos no sentido de concluir e avaliar em que condições o TMI produz alterações na capacidade aeróbia.Escola Superior de Tecnologia da Saúde de Lisboa (Instituto Politécnico de Lisboa)2022-08-25info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.25758/set.1331oai:journals.ipl.pt:article/574Saúde e Tecnologia; No. 15 (2016): Maio 2016; 05-11Saúde & Tecnologia; N.º 15 (2016): Maio 2016; 05-111646-9704reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://journals.ipl.pt/stecnologia/article/view/574https://doi.org/10.25758/set.1331https://journals.ipl.pt/stecnologia/article/view/574/501Direitos de Autor (c) 2022 Saúde & Tecnologiainfo:eu-repo/semantics/openAccessEsteves, FábioSantos, InêsValeriano, JoãoTomás, Maria Teresa2022-12-20T10:58:57Zoai:journals.ipl.pt:article/574Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:21:23.639990Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
