Aquecimento e desaquecimento vocais: revisão sistemática

Abstract

For this literature review, we researched national and international scientific publications on vocal warm--up and cool-down of the speaking voice, through databases such as Lilacs, MedLine and Scielo, in order to identify and describe the methodological parameters and the effects of the vocal warm-up and cool-down proposals that are described in national and international literature. We performed the location and selection of studies through a survey of texts published on the theme from 1999 to 2013. We included original research articles; published in Portuguese or English; with emphasis on vocal warm-up and cool-down; associated or not. The recommended time of execution for warm-up ranged from 15 to 30 minutes or three sets of 15 repetitions, and the cool-down from 5 to 15min. The most used exercises for warm-up were voiced fricative sounds and vibrant of tongue or lips, in ascending scales, and for the vocal cool-down the nasal sounds, fricative sounds and vibrant of tongue or lips, in descending scales, were the most used exercises. The exercises showed positive vocal changes, observed by vocal acoustic and auditory-perceptual vocal and, self-evaluation and aerodynamic related to phonation. There was unanimity on the importance of completing the vocal warm-up and cool-down for voice professionals and on the positive results after carrying out the procedures. There was no agreement on the time of execution and on the exercises that were used.

Foi realizada a localização e seleção dos estudos por meio de levantamento de textos publicados sobre o assunto no período de 1999 a 2013. Foram incluídos artigos originais de pesquisa; publicados na língua portuguesa ou inglesa; que pesquisaram aquecimento e desaquecimento vocal; associados ou não. O tempo de execução recomendado para o aquecimento variou de 15 a 30min ou três séries de 15 repetições, e para o desaquecimento foi de 5 a 15min. Os exercícios mais utilizados para o aquecimento foram sons fricativos sonoros e vibrantes de língua ou de lábios, em escalas ascendentes, e para o desaquecimento vocal foram sons nasais, fricativos sonoros e vibrantes de língua e ou de lábios, em escalas descendentes. Os exercícios mostraram mudanças vocais positivas, observadas por meio de medidas vocais acústicas e perceptivoauditivas, de autoavaliação e aerodinâmicas relacionadas à fonação. Houve unanimidade quanto à importância da realização do aquecimento e desaquecimento vocais para profissionais da voz e aos resultados positivos após a realização dos procedimentos.

A Pilot Survey of Warm-Up Practices and Perceptions Among Indian Classical Singers

“…An average duration of 15À30 minutes has been reported by most studies as per the systematic review. 8 Miller 11 has advised against having vocal warm-up regimes that are longer than 30 minutes.…”

“…Voice changes have been reported in terms of acoustic, auditory-perceptual, aerodynamic, and self-evaluation measures. 8 Singers have noted changes in tonal quality, proprioceptive feedback, psychophysiological factors, and technical commands. An enhanced tonal vibrato quality has been observed not just by the singers themselves but also by the listeners.…”

“…Ribeiro et al 8 systematically reviewed the literature to study the effects of vocal warm-up and cool-down, and to describe the different methodological parameters involved. The review commented upon the lack of agreement about time for exercises for vocal warm-up and their duration.…”

Aquecimento e desaquecimento vocal em professores: estudo quase-experimental controlado

“…VWU consists in a short series (15 to 30 minutes) of progressive exercises (12) that aims to protect the larynx from phonotraumatic lesions. VWU prepares the vocal apparatus for intense voice use by means of respiratory airflow control, head and neck movements and flexibility of the extrinsic and intrinsic muscles of the larynx.…”

“…VCD consists in a sequence of short hierarchically organized exercises (5 to 15 minutes) (12) that aim to gradually place the voice back in its habitual muscular adjustment. By stretching the muscles involved, the practice helps to reduce the tension caused by intense voice use, in addition to reducing the fundamental frequency (f0) and intensity, which are key to vocal overload.…”
