“…In our study, 8 weeks of IMT promoted a reduction (5.7%) in the AHI. Lin et al (2020) 12 have also reported similar results, a decrease in the AHI (6%) in OSA patients after 12 weeks of IMT. Despite a statistically significant reduction in the AHI, these findings AHI could not be clinically relevant.…”

“…24 The results of these studies are conflicting and might be explained by the sample size and the different protocols used for the IMT. Although our study and two others are randomized clinical trials, 10,12 they have a small sample size, ranging from 8 to 12 patients being exercised. Moreover, only few studies exist that assess the effect of IMT on OSA severity, with different durations of IMT intervention, resulting in heterogeneity among studies.…”

“…There are only three studies that address the exclusive use of IMT in OSA. [10][11][12] The first study evaluated the effectiveness of a six-week IMT protocol on the plasma catecholamine levels, OSA severity and sleep variables in patients with mild to moderate symptoms. 10 Souza et al (2018) 11 examined the effectiveness of 12 weeks of IMT on the functional capacity of exercise, sleep quality and excessive daytime sleepiness.…”

“…[7][8][9] Concerning OSA, only three studies have reported the exclusive use of IMT in these patients. [10][11][12] Therefore, the aim of this study was to verify the effectiveness of 8 weeks of inspiratory muscle training on the severity and symptoms of OSA in subjects diagnosed with moderate or severe OSA.…”

Purpose: Exercise programs have been considered as an adjuvant treatment in obstructive sleep apnea (OSA). However, few studies have focused on the effects of the inspiratory muscle training (IMT) in reducing the severity and the symptoms of OSA. Patients and Methods: A randomized controlled trial was conducted and approved by the local Ethics Committee. All subjects signed the informed consent form and were randomized into 2 groups: a) IMT group (n = 8), 8 weeks of IMT with 75% of maximal inspiratory pressure (MIP) and b) placebo group (n = 8): subjects performed IMT without load. Results: IMT group showed reduction in the apnea-hypopnea index (AHI) (p = 0.01), in the Berlin questionnaire score (p = 0.001) and an increase in inspiratory muscle strength (p = 0.018). IMT group demonstrated a reduction in the AHI (31.7 ± 15.9 events/h vs 29.9 ± 15.8 events/h; p <0.001), in the Berlin questionnaire scores (2.6 ± 0.5 vs 1.2 ± 0.5; p = 0.016), Pittsburgh Sleep Quality Index (PSQI) score (7.2 ± 3.6 vs 3.7 ± 1.3; p = 0.008), in the Epworth Sleepiness Scale (ESS) (12.5 ± 4.0 vs 7.7 ± 3.0; p = 0.008) and increase in MIP (83.6 ± 26.5 cmH 2 O and 127.9 ± 32.5 cmH 2 O; p = 0.010). Conclusion: The IMT promotes discrete changes in the AHI and improves sleep quality and excessive daytime sleepiness in OSA. Moreover, IMT is a cheap, useful and simple homebased training program and can be considered as an adjunct therapy for OSA patients.

“…Alguns estudos randomizados [7][8][9] realizaram protocolos de treinamento da musculatura respiratória em pacientes com SAOS de diferentes graus, durante um período entre 5 e 12 semanas. Foi observado que o fortalecimento dessa musculatura contribuiu para a melhora da qualidade do sono e redução do número de apneias noturnas.…”

Introdução: A síndrome da apneia obstrutiva do sono (SAOS) é caracterizada pela obstrução das vias aéreas superiores durante o sono, o que causa efeitos sistêmicos durante a vigília. Objetivo: O objetivo deste estudo é avaliar a capacidade funcional, a força da musculatura respiratória e o pico de fluxo expiratório (PFE) de pacientes com SAOS. Métodos: Trata-se de um estudo transversal realizado na cidade de Patos de Minas/MG no ano de 2019, no qual foram incluídos 14 indivíduos que possuíam SAOS moderada e grave. Primeiramente os pacientes responderam a um questionário sociodemográfico elaborado pelos autores. Em seguida, foi realizada a manovacuometria, a mensuração do PFE e o teste de caminhada de seis minutos (TC6M). Resultados: A maioria dos pacientes eram homens (71,4%), obesos (78,6%) e hipertensos (57,1%). Como resultados dos testes obtivemos - PImáx obtida vs predita = 86,4 vs 102,8 (p = 0,004), PEmáx obtida vs predita = 98,5 vs 113,5 (p = 0,05), PFE obtido vs predito = 381,3 vs 495,8 (p < 0,001) e TC6M obtido vs predito = 485,3m vs 536,6m (p = 0,03). Conclusão: Nessa amostra de indivíduos com SAOS grave e moderada houve redução da força muscular respiratória, do PFE, e da capacidade funcional.Palavras-chave: síndromes da apneia do sono, músculos respiratórios, tolerância ao exercício.
