Effect of Breath Stacking on Phonatory outcomes and Chest Expansion in Female Folk Singers
Abstract: Background: Breathing plays an important role in singing, particularly in folk singers who require adequate respiratory control and endurance for sustained vocal performance. Breath Stacking is a lung volume recruitment technique that involves successive inspiratory efforts without expiration and may improve lung volume, chest expansion, and phonatory performance. Objective: To determine the effect of Breath Stacking on chest expansion and phonatory outcomes in female folk singers and to compare its effectiveness with Pursed Lip Breathing. Design: Randomized Controlled Trial. Setting: Department of Music, Khalsa College, Amritsar. Methods: An experimental randomized controlled trial was conducted among 48 female folk singers aged 18-25 years at the Department of Music, Khalsa College, Amritsar. Participants were randomly allocated into two groups of 24 each. The intervention group (Group A) received Breath Stacking, while the control group (Group B) received Pursed Lip Breathing. The intervention was administered 4 days per week for 4 weeks. Maximum Phonation Time (MPT) and chest expansion were assessed before and after the intervention. Within-group changes were analysed using paired t-test, while between-group differences were analysed using an unpaired t-test. Results: Both groups showed significant improvements in Maximum Phonation Time and upper and lower chest expansion after 4 weeks (p
