Purpose: The present study aimed to observe whether physiological warm-up and traditional singing warm-up differently affect aerodynamic, electroglottographic, acoustic, and self-perceived parameters of voice in Contemporary Commercial Music singers. Methods: Thirty subjects were asked to perform a 15-minute session of vocal warm-up. They were randomly assigned to one of two types of vocal warm-up: physiological (based on semi-occluded exercises) or traditional (singing warm-up based on open vowel [a:]). Aerodynamic, electroglottographic, acoustic, and self-perceived voice quality assessments were carried out before (pre) and after (post) warm-up. Results: No significant differences were found when comparing both types of vocal warm-up methods, either in subjective or in objective measures. Furthermore, the main positive effect observed in both groups when comparing pre and post conditions was a better self-reported quality of voice. Additionally, significant differences were observed for sound pressure level (decrease), glottal airflow (increase), and aerodynamic efficiency (decrease) in the traditional warm-up group. Conclusion: Both traditional and physiological warm-ups produce favorable voice sensations. Moreover, there are no evident differences in aerodynamic and electroglottographic variables when comparing both types of vocal warm-ups. Some changes after traditional warm-up (decreased intensity, increased airflow, and decreased aerodynamic efficiency) could imply an early stage of vocal fatigue.
