About

This study aims to investigate the effects of combined SOVT and breathing exercises, administered twice weekly for six weeks to conservatory students, through a randomized controlled trial. The study has two hypotheses: H1: Combined SOVT and breathing exercises increase the maximum phonation duration. H2: Combined SOVT and breathing exercises improve spirometric parameters (FEV₁, FVC, FEV₁/FVC, and PEF).

Full description

This study aims to investigate the effects of combined SOVT and breathing exercises, applied twice a week for 6 weeks, on conservatory students at Gaziantep University through a randomized controlled trial. The study has two hypotheses: H1: Combined SOVT and breathing exercises increase maximum phonation duration. H2: Combined SOVT and breathing exercises improve spirometric parameters (FEV₁, FVC, FEV₁/FVC, and PEF). In the intervention group, phonation exercises using a pipette were taught and practiced as part of the SOVT exercise. Simultaneously, pursed-lip breathing, segmental breathing, and diaphragmatic breathing exercises were taught and practiced as breathing exercises. At the end of 6 weeks, the maximum phonation duration of all participants was measured with a stopwatch. Additionally, spirometric parameters were measured using a spirometer.
