Correlation Between Peak Expiratory Flow Rate (P.E.F.R.) And Abdominal Muscles Strength Among Voice Over and Dubbing Artists: A Correlational Study

Introduction: Voice over &dubbing artists are professionals who uses their voice to portray characters or provide information to an audience to entertain them. These artists use abdominal breathing rather than thoracic breathing. Respiratory function has correlation with voice production and quality. Pulmonary function tests can be used to assess the voice of a person. There is less literature support for nature of abdominal muscle activation among professional voice users. In this study the correlation between Peak Expiratory Flow Rate (P.E.F.R.) and abdominal muscle strength will be assessed Method: 50 Voice over and dubbing artist with experience of at least 6 months in voice industry among which 17 were females and 33 were male artists within age group of 18-25 years were approached and consented for the assessment. Peak Expiratory Flow Rate (P.E.F.R.) were assessed using Peak Flow Meter and strength of abdominal muscles were assessed using pressure biofeedback unit. The statistical data was then analyzed for the result. Results: Linear regression test was performed to find the correlation between the Peak Expiratory Flow Rate (P.E.F.R.) and abdominal muscles. The statistical analysis of P.E.F.R. and abdominal muscles strength was calculated to be significant. The test showed significant results with p value <0.0001. Correlation coefficient (r) is 0.1959. Conclusion: it was concluded that there is correlation between Peak Expiratory Flow Rate (P.E.F.R.) and Abdominal Muscles Strength among voice over and dubbing artists. Key words: Voice over artists, dubbing artist, P.E.F.R., abdominal muscles, pulmonary function tests
