Abstract EN

The research includes five chapters , first chapter Include with the front and touched researchers where Alydor senses to influence the learning process in general and especially volleyball The importance of research are: try to find exercises visual skill capable of developing performance variables Biomechanics for my skills handling of top and bottom and working on the economy the time and effort required to develop them, and that is one of the mission, things that occupy the attention of a lot of those in charge of education and training of teams and sports teams, research problem, which is limited to the following question: Is the exercises visual skills prepared by play a role in the development of some Biomechanics variables in the performance of my skills handling of top and bottom Volleyball new, objective research are: preparation exercises visual skill to develop some variables Biomechanical performance of my skills handling of top and bottom volleyball and identify the impact of visual exercises skills in the development of some of the variables Biomechanics performance of my skills handling of the top and the bottom plane of the ball impose Search: visual exercises a positive impact in the development of some of the variables Biomechanics performance of my skills handling of top and bottom Volleyball research areas of the human sphere: neo-educated sincere Sports Club in sight province, field temporal: time of 10/1 period / 2016 until 04/01/2016 and spatial field: volleyball court in a sincere Sports Club, the term visual exercises footwork is a set of exercises that were developed and built in a way to speed the development of education and skill performance guarantees Chapter II theoretical studies, Chapter third, it adopted and which is the experimental method experimental sample per guarantees, research sample (16) learner of new learners, designed researchers visual exercises and the gentlemen specialized experts in volleyball and Biomechanics were then placed in a prepared training program by including coach 20 educational unit, was conducted imaging tribal and posttest of the sample in the stadium set, Chapter IV contained a presentation and discussion of results, Chapter V included conclusions: that the visual exercises an important role in all the variables Biomechanics in the performance handling of supreme skill, developed the visual exercises all Biomechanics variables in performance handling of lower skill the most important recommendations: the need to adopt visual exercises footwork prepared by the trainer in the evolution of Biomechanics variables and thus performance skills of from the top and the bottom volleyball, research into building exercises visual skill to the skills of the other and see how they affect performance variables
