The feedback method is increasingly used in learning new skills and improving performance. "Recent research, however, showed that the most objective and quantitative feedback is, the greater its effect on performance". The video analysis, which is the analysis of sports performance by watching the video, is used primarily for use in the quantitative performance of athletes through the notational analysis. It may be useful to combine the quantitative and qualitative analysis of the single gesture for use in technical training in real time. Currently there are no specific studies on volleyball on the use of performance analysis during training. The scope of work is to carry out a preliminary study on the use of video analysis in volleyball recruiting quantitative and qualitative data to build a model to describe executive motor and propose a total athlete and analytically for each athletic ability. This training method is part of the planning of educational training to improve the performance of athletes. Using video analysis of technical movements of the attack, carried by four athletes in training, the category under 13 years old, which will be compared to a video-execution model of reference. The benchmarks are: Optimum preparation for the strike on the ball and angle of the body with the floor; Horizontal Speed and Step Length (left foot); 2 Next Steps (right-left), and their length, angle of the arms; Phase Out , hit the ball and reached the heights from knee and hand; fallout on the ground with both feet. The four athletes will be divided into two groups of two people: Both group A, the control group, than the B group, the experimental group, will be filmed at the beginning and end of the project, and every day in training, both groups following the same training program, for 30 meetings. Group A will not be provided feedback during the course of their performance, while group B will be offered every day, the video of the execution of the fundamental attack took place during the previous exercise. At the end of the research, comparison will be made between the beginning and end of video and educational activities between the control group and the experimental group for each training done, to verify the improvements, to note the differences between the groups. The differences in the comparison of results will contribute to the choice of this method in training and possibly deepen the issue in other ways.
