Investigating how respiratory muscle training affects tongue muscle function

What this trial studies

This study aims to explore the impact of respiratory muscle training on tongue muscle function in healthy individuals. The researchers hypothesize that both Inspiratory Muscle Training (IMT) and Expiratory Muscle Training (EMT) will enhance tongue strength compared to a control group. The study will involve community ambulant adults aged 18 to 65, who will undergo different training interventions to assess improvements in tongue muscle function. The findings may provide insights into potential benefits for patients with obstructive sleep apnea based on previous studies.

Inclusion Criteria:

Community ambulant adults between 18 to 65 years old as of testing day; able to understand French or Dutch (depending on the study's site of inclusion); BMI ≥ 18 and ≤ 30 kg/m².

Exclusion Criteria:

Any diagnosed neuromuscular or cardiorespiratory disease; diagnosed psychiatric or psychological disorders which could affect adherence to or comprehension of instructions; diagnosed eating disorders; previous or ongoing head and neck cancer; diagnosed OSA; presenting a high-risk of sleep-disordered breathing indicated by a NoSAS score of 8 or higher 32 or a STOP-Bang score of 3 or higher 33,34; resting heart rate (HR) \> 100 beats per minute (bpm) or \< 50 bpm; resting systolic blood pressure (SBP) \> 140 or \< 90 mmHg, diastolic blood pressure (DBP) \> 90 or \< 50 mmHg; oxygen saturation (SpO2) \< 94% at rest on room air. Individuals with abnormal lung function, i.e., forced expiratory volume in 1 second (FEV1) ≤ 80%, forced vital capacity (FVC) ≤ 80%, and FEV1/FVC ≤ 70%, will also be excluded.
