Abstract EN

This study aims to identify the effect of equilibrium exercises (Static - Dynamic) on the angular change of the pivot foot and its relationship with biomechanical indicators and the effectiveness of the performance of the instep kick of the soccer junior.

The researchers used the experimental approach with only one experimental group considering the pre and post measurements in addition to the biomechanical analysis.

The study sample was intentially selected, including 10 soccer juniors under 15 years old.

The results of the study indicated that the (Static - Dynamic) balance exercises have positively affected the angular change of the pivot foot for the soccer juniors, that resulted in better directing of the biomechanical indicators of the kicking foot while kicking the ball, and so the improvement in the effectiveness of the instep kick, represented by the time and accuracy of kicking the ball.

the results also indicated that there is a correlation between the angular change of the pivot foot and the biomechanical indicators of the kicking foot and the effectiveness of the instep kick of the soccer junior.

Accordingly, the researchers recommend that coaches should pay attention to developing (Static - Dynamic) balancing through training programs as much as attention to other physical variables.

Also the change that occurs in the joints of the pivot foot during the instep kick should be linked to the biomechanical indicators of the kicking foot and the effectiveness of kicking the ball represented in the accuracy and time of kicking , as this change may affect, positively or negatively, the accuracy and time of kicking the ball.
