BRENNECKE, Allan; AMADIO, Alberto C.  and  SERRAO, Júlio C.. Dynamic parameters of selected movements of "Capoeira". Rev. Port. Cien. Desp. [online]. 2005, vol.5, n.2, pp.153-159. ISSN 1645-0523.

Considering the limited scientific information concerning a biological focus on "Capoeira", the aim of this study was to conduct a dynamic analysis of selected movements of "Capoeira" in the scope of Ground Reaction Force (GRF). The sample consisted of 10 "capoeiristas". All of them performed the following movements: "Negativa Fechada", "Martelo", "Armada Pulada" and "Parafuso" in a Force Plate. The analysis of the GRF curves was centered in the Maximum Vertical Force (Fy max), in the Time to achieve Fy max Peak (TFy max), in the Vertical Force Growth Rate (GR Fy) and in the Impulse generated for Fy in first 50ms of movement execution (I50). Reflecting the behaviour of  Fy(max) and TFy(max), the smaller values for GR Fy and I50 were obtained by "Negativa Fechada" (4,91±4,69 PC·s^-1 ; 1,53±0,76·10^-2 kg^.ms) and by "Martelo" (2,61±1,70 PC·s^-1; 0,84±0,41·10^-2 kg^.ms), while the "Armada Pulada" (115,93±79,84 PC·s^-1; 7,54±3,04·10^-2 kg·ms) and "Parafuso" (69,17±65,68 PC·s^-1; 6,38±2,88·10^-2 kg·ms) showed the major values for these variables. The present study brings evidences that, at least in the scope of external forces, the "Negativa Fechada" and "Martelo" could be inserted in the initial phases of training program, whereas the "Parafuso" and "Armada Pulada", movements whose mechanical and motor demands are greater, could be approached later in the same program. However, a cautionary note should be present in these results since the received overload depends not only of the osteomioarticular structures conditions of the practiser, but also of their level of physical conditioning.
