Combined SOVT and Respiratory Exercises: Effects on MPT and Respiratory Function

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).
