Abstract(s)
Objetivo: O objetivo do presente estudo é comparar a atividade eletromiográfica dos músculos deltóide posterior, deltóide anterior, infraespinhoso e de ambas as porções do peitoral em diferentes variações dos exercícios press-up box e prancha com diferentes níveis de estabilidade. Metodologia: Foram avaliados 15 indivíduos com mediana de idades (22.00 ± 2.00 anos) e mediana do IMC (23.41 ± 3.83). Avaliou-se a atividade eletromiográfica em 6 box position, 3 posições de prancha e 3 posições com o auxílio do TRX. Resultados: Foram encontradas diferenças significativas na atividade eletromiográfica dos diferentes músculos em cada variação e na atividade de cada músculo nas diferentes variações. Na posição de box o valor mais alto foi realizado pelo infraespinhoso (22,10%). Em relação às superfícies instáveis o valor mais alto foi encontrado pelo peitoral porção esternal (32,74%), enquanto nos exercícios em suspensão foi o infraespinhoso (47,09%). Todos os músculos tiveram a maior atividade muscular numa posição de prancha. Conclusão: Conclui-se que a adição da instabilidade nas posições de prancha apenas tem um efeito positivo no recrutamento muscular do peitoral, enquanto a passagem para um apoio unilateral apenas resulta no deltóide posterior e no infraespinhoso. Logo nem todos os músculos beneficiam destas variações estudadas.
Objective: The aim of the present study is to compare the electromyographic activity of the anterior deltoid, posterior deltoid, infra-spinous, pectoralis sternal and clavicular portion during different variations of the box and plank position with different stability levels. Methodology: There were evaluated 15 individuals with median age (22.00 ± 2.00 years) and median body mass índex (23.41 ± 3.83).The electromyographic activity was evaluated in 6 box position, 3 plank positions and 3 positions witk the help of TRX Results: Statistically significant differences were found for sEMG between different muscles in each variation, and for each muscle across different variations. In the box position the highest value was found in the infra-spinous (22,10%). In relation to unstable surfaces the highest value was found in the pectoral sternal portion (32,74%), meanwhile in the suspended exercicies it was the infra-spinous (47,09%). All the muscles had the highest muscular activity in a plank position. Conclusion: We concluded that the adition of instability in the plank positions only has a positive effect in the muscular recruitment on the pectorallis, while moving to a unilateral support only works in the posterior deltoid and the infra-spinous. Therefore not all muscles benefit from this variations.
