Objectivo: estudar a actividade muscular no complexo articular do ombro e tronco durante o serviço e a sua relação com o Conflito Sub-Acromial.
Metodologia: estudo observacional, analítico, transversal. Amostra de 15 atletas de voleibol distribuídas em 3 grupos e avaliadas através de electromiografia de superfície em músculos do ombro e do tronco. Foi avaliada a percentagem de activação muscular nas diferentes fases do serviço.
Resultados: aumento de actividade do Trapézio Superior e Infraespinhoso e diminuição do Recto Abdominal e Oblíquo Externo no grupo com Conflito Sub-Acromial.
Conclusão: existem diferenças significativas nas atletas com e sem Conflito Sub-Acromial.
Objective: analyze the muscle activity of the shoulder complex during the volleyball serve and the possible correlation with the mechanism of injure of impingement syndrome. Methods: observational, analytic, transversal study. 15 athletes were divided in three groups and evaluated with surface electromyography. It was study the mean of muscle activation during the different fases of the serve. Results: increased activity in Upper Trapezius and Infraspinatus and a decreased activity in Rectus Abdominis and Obliquus Externus in athletes with impingement syndrome. Conclusion: athletes with and without impingement syndrome have significant different muscular activity levels in stabilizers.
