TL;DR
This study found that 28 days of inspiratory muscle training improved vocal efficiency and aerodynamic control in women without vocal complaints.
Contribution
The study demonstrates that inspiratory muscle training can enhance vocal performance in individuals without pre-existing vocal issues.
Findings
Acoustic analysis showed a decrease in Shimmer % and an increase in HNR after training.
Maximum phonation times and diadochokinesis syllable repetition rates improved significantly.
Self-assessment scores indicated better vocal quality and reduced vocal-related limitations.
Abstract
To analyze the vocal effects of inspiratory muscle training for 28 days in women without vocal complaints. The study included 22 women with no vocal complaints who underwent inspiratory training with the Respiron® Classic Breathing Trainer and Stimulator. The training consisted of 2 sets per day of 30 repetitions for 28 consecutive days. Vocal samples were collected pre and post training and compared regarding auditory-perceptual evaluation (APE), acoustic analysis, aerodynamic and diadochokinesis measurements, and vocal self-assessment. The data was statistically analyzed using dependent tests. No differences were found in the APE of the sustained vowel /a/ and number counting. Differences were found in the acoustic analysis, with a decrease in the median Shimmer % and an increase in HNR. There was an increase in the average maximum phonation times of the vowel /i/, of the fricatives…
