From Core to Chords: Transforming Vocal Performance with Core-cardio Exercises

Abstract

This study investigates the impact of core-cardio exercises on the vocal performance of choral group members, aiming to enhance singing abilities through improved breath control, posture, and overall physical fitness. The research involved an experimental group that engaged in core-cardio exercises alongside vocal warm-ups and rehearsals for eight weeks, while a control group participated only in short vocal warm-ups. Initial assessments showed comparable vocal performances in both groups. The post-intervention evaluations revealed that the experimental group demonstrated significantly greater vocal proficiency than the control group (t(71) =50.156, p <.001). Also, statistical analyses confirmed the positive effects of core-cardio exercises on vocal performance across different time intervals (χ²(3) = 137.988, p < .001). The findings underscore the value of integrating physical training into vocal education, as core-cardio exercises enhance cardiovascular health and improve vocal stamina and strength. These results suggest that choral conductors, choir members, educators, and performing arts organizations should incorporate core-cardio exercises into their training programs to optimize vocal capabilities and enhance overall performance. Future research is recommended to explore qualitative insights from choral directors and to investigate additional physical training modalities, such as high-intensity interval training (HIIT) and Pilates, to diversify further and enrich vocal training methods. By adopting a holistic approach that combines physical fitness with vocal training, this study contributes to a deeper understanding of effective practices for developing choral singers' vocal abilities.
