Armlock in the closed guard: kinematic consequences to the kinetics of the technical gesture
Ronald Condé · 2018
The present work had for objective to analyze the Brazilian jiu jitsu technical gesture known as Armlock, which has been executed from the Closed guard aiming at the identification of the bodily interactions resulted from its execution under a kinesiological view. Research methods. Filming, photography, pictures and softwares, from which it has been possible the rationalization of the proceedings adopted in this analysis. Results. The opponent does not figure only as target, taking into account that he is understood as a necessary implement to accomplishment of the blow that reaches him, so that it has been reputed essential taking also him as an axis of movement through which it’s possible one articulates and attains an ideal angle from which it is viable to complete the lever and, consequently, the attack can be consummated. Conclusion. Considering the multiple relations of interdependency between the attacker and the opponent, articulating both on himself and on his opponent, it was tried to reach not only a kinesiological description of the Armlock, but also the rationalization of the entire kinematics of the technical gesture studied. Through the analysis of the recorded images, at first it has been verified the need for angular displacement so that there is full employment of all kinetic sources involved in the lever of the blow, and from the quantification of the trajectory of the three Run Modes, it has been possible to identify the mode in which the Armlock is liable to be optimized, since it presents the shortest distance until the lever zone, that which can result not only in advantages in terms of energy saving, but also in terms of safety for the attacker, enabling him to perform the transition without expose himself too much, when he opens his own guard in order to reach the lever zone. Far from exhausting the subject, one expects to have contributed to further studies, accordingly, adapting to the lack of theoretical references and taking advantage of the best possible form of empirical knowledge of the Masters and Sport Coaches, without, however, imply the abstraction of the opponent, which, constituting a component of the gesture, is fundamental to its perfect intelligibility.
