NCT05242406

Brief Summary

It was aimed to investigate the effect of expiratory muscle strength training (EMST) applied at different intensities on systemic inflammation and oxidative stress in patients with moderate obstructive sleep apnea syndrome (OSAS). In the study, 32 male patients diagnosed with moderate OSAS will be included in the study. Participants will then be divided into 2 groups by block randomization. In the three-blind planned study; the first group will receive high-intensity %60 maximum expiratory pressure (MEP) EMST training, and the second group will be given low-intensity 30% of MEP, EMST training for 12 weeks. Disease-related symptoms, disease severity apnea-hypopnea index (AHI), oxidative stress index (OSI) and systemic inflammation level, exercise capacity, respiratory muscle strength, sleep quality, daytime sleepiness, and fatigue severity will be evaluated before and after the study.

Outcome Measures

Primary Outcomes (7)

  • Disease severity

    Polysomnography recordings will be taken especially sleep efficiency and apnea-hypopnea index (AHI). Higher sleep efficiency and lower AHI values shows that patient have better status and lower disease severity

    2 days

  • Oxidative stress-1

    TAS:Venous blood sample will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning after an overnight fast and will be analyzed with a colorimetric kit.

    5 days

  • Systemic inflammation-1

    CRP:biochemistry laboratory will work on the Abbott Architect C4000 (USA) clinical chemistry autoanalyzer.

    5 days

  • Systemic inflammation-2

    TNF-a:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.

    5 days

  • Systemic inflammation-3

    IL10:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.

    5 days

  • Systemic inflammation-4

    IL-6:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.

    5 days

  • Oxidative stress-2

    TOS:Venous blood sample will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning after an overnight fast and will be analyzed with a colorimetric kit.

    5 days

Secondary Outcomes (5)

  • Exercise capacity

    2 days

  • Maximal inspiratory and expiratory muscle strength

    2 days

  • Daytime sleepiness

    2 days

  • Fatigue severity.

    2 days

  • Sleep quality

    2 days

Study Arms (2)

H-EMST

EXPERIMENTAL

In 60% of the maximum expiratory pressure (MEP), 25 breaths a day, 7 days / week, a total of 12 weeks will be trained with a 1-minute rest cycle in 5 breaths. Patients will be invited to control every 2 weeks. MEP measurements will be repeated and the training value will be adjusted in 60% of the new measurement.

Other: Expiratory muscle trainig

L-EMST

EXPERIMENTAL

At 30% of the maximum expiratory pressure (MEP), 25 breaths, 7 days / week, a total of 12 weeks will be trained once a day with a 1-minute rest cycle in 5 breaths. Patients will be invited to control every 2 weeks. MEP measurements will be repeated and the training value will be adjusted in 30% of the new measurement.

Other: Expiratory muscle trainig

Interventions

This exercise will be used to strengthen forced expiratory muscles.
