TI  - Water Resistance Therapy as Vocal Warm-Up Method in Contemporary Commercial Music 
      Singers.

AB  - BACKGROUND/AIMS: Although water resistance therapy (WRT) has been widely used in 
      voice training, no data are supporting the effectiveness of WRT as vocal warm-up 
      for singers. The present study aimed to determine the effects of WRT as a vocal 
      warm-up method in contemporary commercial music (CCM) singers. METHODS: 
      Twenty-two CCM singers were randomly assigned to one of two types of 15-min vocal 
      warm-up: open vocal tract (OVT) warm-up and WRT. Self-perceived resonant voice 
      quality and aerodynamic, electroglottographic, and acoustic measures were 
      assessed before, immediately after vocal warm-up, and after 40 min of vocal 
      loading. RESULTS: Significant results were found immediately after vocal warm-up. 
      Subglottic pressure and inspiratory airflow duration decreased in both groups. 
      SPL decreased for the OVT group. No changes in SPL were found for the WRT group. 
      Significant results were observed after vocal loading. Subglottic pressure and 
      inspiratory airflow duration decreased for both groups after vocal loading. 
      Expiratory airflow duration and electroglottographic contact quotient decreased 
      for the OVT group. CONCLUSION: Some objective data suggest that the WRT method is 
      more effective as vocal warm-up than OVT exercises. Since outcomes in 
      self-perceived resonant voice quality for both methods were similar but 
      physiological effects were different, vocal warm-up strategies might produce a 
      placebo effect.
