Abstract(s)
Avaliar os níveis de actividade e grau de simetria dos músculos esternocleidomastoideo e masséter em estudantes de canto. Foi utilizada uma amostra constituída por 8 e 13 estudantes e não estudantes de canto, respectivamente. Foi registado o sinal electromiográfico durante provas de canto a diferentes intensidades. Não ocorreram diferenças entre o masseter direito e esquerdo e esternocleidomastoideo direito e esquerdo nos dois grupos. Ocorreram diferenças na activação dos músculos esternocleidomastoideos quando comparadas as provas média-forte e fraca-forte. Os estudantes de canto não apresentaram assimetrias musculares, sendo o grau de actividade do músculo esternocleidomastoideo influenciado pela intensidade.
To assess the levels of activity and degree of symmetry of the sternocleidomastoideus and masseter muscles in singing students. The sample consisted of 13 non-sininging students and 8 singing students. Electromyographic signal was recorded during the singing tests at different intensities. Results: There were no differences between the right and left masseter and right and left sternocleidomastoideus in both groups. There were differences in the activation of the sternocleidomastoideus muscles during medium-strong and weak-strong singing tests. Singing students showed no muscular assymmetry, and the degree of activity of the sternocleidomastoideus muscle was influenced by the intensity.
