Résumé:
The delimiters are the most important tools, widely used in training
and tests soccer, because they embodies the dimensions of the surface and
the role of defender in major of the exercises for Soccer. That literature
review 90% of soccer books use the smallest delimiters (plate) and 100% of
our young soccer Algerians coaches (under 15 year) composed their
sessions. from that the objective of our study focuses on the different forms
and volumes of these last lend, based on these differences our hypothesis
confirms that they affected the information (indicators from the external
environment) and qualities coordinators during the change of direction
(obstruction of the upper body player). Our experience is based on a practical
protocol of Vankersschaver Jacques1982 from his study entitled "Role of
Visual Index and Cognitive Process in the Acquisition of a Gesture Football
Technique”. Were we have introducing the different kinds of delimiters
(fig1) and the inactive player to determine the most type of delimiter
appropriate to evaluate and train duels with ball in young soccer. Were our
finding confirmed: (1) The mannequin is the most delimiter appropriate for
testing and progress in duels soccer. (2) The progress in training duels
requires the smallest (familiar with the gest) arrive at the mannequin to
perform with the gest (1vs1). (3) The objective of duels requires the
involvement of the commitment of peripheral vision for information and
central vision to master the ball. From that, the best dribbler is the player
who lifts his head when he moves with the ball.
