Resumo

Introdução: Ao praticar o Adho Mukha Vrksasana, os deltóides desempenham um papel fundamental. No entanto, não foram realizados estudos para determinar qual dos três músculos deltóides contribui mais ou menos para a prática de Adho Mukha Vrksasana.

Objectivo: Este estudo comparou o padrão de activação muscular dos deltóides durante a prática de Adho Mukha Vrksasana.

Metodologia: Foram selecionados 30 (N=30) praticantes de yoga do sexo masculino com uma média de idades de 21,4 ± 1,85, uma altura de 165,2 ± 2,3 cm e um peso de 61,2 ± 4,6 kg. A videografia, pós-processada com o software de análise de movimento Kinovea 2D, foi utilizada para calcular o ângulo do pescoço (em graus) e a altura do centro de gravidade (CG) (em cm). A eletromiografia (EMG) sem fios foi utilizada para comparar as respostas da atividade muscular de todos os músculos deltoides selecionados. Foi utilizada uma ANOVA com um nível de significância de 0,05.

Resultados: Foi observada uma diferença significativa entre os músculos deltóides selecionados aquando da realização de Adho Mukha Vrksasana (F = 84,887; p ≤ 0,05). O deltóide medial apresentou uma melhoria significativa, seguido do deltóide posterior e, por último, do deltóide anterior. A altura média do centro de gravidade foi de 95,86 cm e o ângulo médio do pescoço foi de 103,66°.

Discussão: O estudo anterior demonstra a contribuição significativa do deltóide lateral (medial) ao realizar o Adho Mukha Vrksasana.

Conclusões: O ângulo médio do pescoço foi de 103,66°. A altura média do CG foi reportada como sendo de 95,864 cm e a ativação muscular média de cada um dos três músculos deltoides não foi igual à média de 41% do deltóide medial, 32% do deltóide posterior e 27% do deltóide anterior.
