Dynamic Analysis of the Instep Kicking
The study shows the dynamics and phases of the elements that act in an instep kicking.
Introduction
Although there are different ways of hitting a ball, the analysis was carried out on the instep, since it allows a more regular contact surface; as well as the conditions of the influencing elements in kicking dynamics. By means of mathematical methods and high-speed cameras, it was possible to quantify and represent the speed and accelerations of the foot and the ball and its center of gravity CGB, as well as the restitution force of the ball.
Methods
Subjects
Expert soccer players.
Testing and analysis
Balloon, cameras and software and software analytical methods.
The linear transformation DLT
Calibration of the 3 dimensions
Least squares method
Obtaining the curves of behavior curves
Results
Velocity, acceleration, displacement and reaction force curves.
Multiaxial foot interaction lasts impact.
95% ball speed occurs in phase III, the foot and the ball stop interacting when phase IV begins.
The impact interaction phases last 10 ms and at 4 ms the maximum deformation occurs.
Conclusions
The movement of the CGB and the deformation of the ball during the impact can be
IV phases are presented during the deformation ball.
The foot experiences axial movement during impact.
The maximum reaction force is 2930N.
