Biomechanical Aspects of the Lower Limb Positions to the Direct Free Kick at Football

This paper present the aspects regarding the kinematics analysis of the human lower limb, respectively the angular positions and the angular velocities of the body segment, thigh, leg and foot, during of the direct free kick at football. For the analysis were videotaped the direct free kicks of 10 human subjects, children between 10 and 13 years, after which the images were processed using a specialized software. The method of the direct experimental kinematics analysis it allowed the determination of the amplitudes and the angular speeds segmentation advisable for to obtain accurate kicks in the direct free kicks with the ball. Regarding the performance, the objective pursued was that the ball must to have a trajectory on the space of the gate and also exceed the human wall which it is in front of the gate.
