The participant is asked to take a deep breath and not exhale.\n\nc. The participant is instructed to place the mouthpiece behind their teeth, inside their mouth, and press their lips firmly against the mouthpiece, pressing down on the sides of their cheeks if necessary.\n\nd. Participants are instructed to exhale forcefully and quickly, using their chest and abdominal muscles to push the air through the device. This exhalation effort should only take a few seconds for the air to pass.\n\ne. Participants are instructed to rest for at least 15-30 seconds, and to rest between breaths as well. The muscles need time to prepare for the next set.\n\nf.

Voice disorders often result from inadequate respiratory support, leading to compensatory laryngeal overuse, vocal fatigue, and deterioration in voice quality. Although traditional voice therapy emphasizes diaphragmatic breathing, it does not enhance respiratory capacity because it lacks resistance. This study aims to investigate the effects of resistance-based breathing exercises using the Expiratory Muscle Strength Trainer (EMST 150) and triflo devices on respiratory capacity, acoustic and aerodynamic voice parameters, and vocal fatigue in academics. The findings are expected to contribute to the literature and support the use of EMST as a preventive and therapeutic approach for occupational groups at risk of voice disorders.",[93,94,95,96,97],"Voice Fatigue","Voice Disorder","Academic Voice Use and Voice Fatigue","Academician's Risk of Developing Voice Disorder","Voice Disorder Prevention in Academics",[99,100,101,102,103],"Voice Disorders","Vocal Fatigue","Professional Voice Users","Respiratory Muscle Training","Acoustic Analysis","NOT_YET_RECRUITING","2026-01-19",{"date":107,"type":108},"2026-01-27","ACTUAL",{"date":110,"type":87},"2026-01-10",{"date":112,"type":87},"2026-05-10",{"name":5,"class":6},1]
