Abstract

Acupunture has been used for more than five thousand years in China, and aims to cure diseases by pricking needles into specific body points, and has been used by high-level athletes and amateurs in order to improve performance in sports. However few studies relate acupunture and biomechanics parameters, like force and muscular activation. Electromyography allows the recording of electrical signals from muscle contraction and enables to analyze the effects of this activation on the movement. In this context, the purpose of this study, with preliminary character, is to make a comparative biomechanical analysis of isometric motion in ride before and after application of acupunture in point ST32 for 10 minutes in one volunteer. It was evaluated the activity of vastus lateralis, vastus medialis and rectus femoris, using suface electromyography and the force applied in pedal by a force transducer before and after acupunture application, and all results was correlated. It was found a significant increase (p < .05) in force and vastus medialis activity, and decrease of rectus femoralis activity after acupunture. There wasn't difference in vastus lateralis activity. Acupunture influenced in force generation and in modulation in muscular contraction, probably in all kinetic chain, influencing in movement coordination. It wasn't able to draw a definitive conclusion about the results given the research in only one volunteer. It's suggested more studies about this issue. [PUBLICATION ABSTRACT]
