“…The consistency of the VRP measures from BOS to EOS may have been impacted by variations in warm-up duration and type. For physiologic warm-up tasks like glides and lip trills, between two and 10 min of vocal warm-up has been found to increase the maximum fundamental frequency [84][85][86] and the frequency range [84,86] of voice range profiles. However, traditional warm-up using a real singing task may require 20 min or more to impact acoustic and aerodynamic voice measures [87].…”

Introduction: Vocal performers often seek natural treatments to improve their vocal capability. Omega-3 polyunsaturated fatty acid (PUFA) supplementation may reduce inflammation and cause changes in body composition, such as loss of fat mass. The purpose of this study was to determine if omega-3 PUFA supplementation in combination with a singer’s training regimen enhances singing training and body composition. Methods: This was a non-randomized, double-blind, placebo-controlled trial. Forty-three college-level students were recruited and volunteered to serve as study participants. 3.0 grams of omega-3 PUFA per day or 3.0 grams of placebo per day were provided over a 10-week intervention. Participants completed Singing Voice Handicap Index (SVHI), Reflux Symptom Index (RSI), Evaluation of Ability to Sing Easily (EASE), Voice Range Profile (VRP), food records and body composition measures at baseline and study end. Results: Thirty-five participants completed the study. SVHI was significantly different between groups (p = 0.0152; ƞ2 = 0.153). A minor third was added to the bottom of the range in 50% of males in the supplement group (placebo = 0%). Body composition measures were not statistically significant, although those in the supplement group lost more fat mass than placebo, p = 0.101. Discussion/Conclusion: Omega-3 PUFA supplementation may be beneficial to improve how active singers feel about their voice and could potentially improve voice range in conjunction with voice lessons, however more research is necessary to confirm the latter.
