Abstract
Background. Since 2006, at the Faculty of Sport Sciences of Montpellier, to train students in the use of sportive video analysis with general and specific software, students must build 4 specific applications. These ICT skills are part of those defined by the Ministry of Higher Education, and the feature of these applications is the use of "delayed videos" analysis. Their learning journey is supported by on line tutorials. To consider the ever-increasing efficiency of new technologies and go further in video analysis, we have added a step (a fifth application): the use of "live videos" analysis excluding the backtracking of video. The benefits of this type of work can help decision-making in everyday life and therefore concern the world of sport.Problem. The purpose of this work was to observe students analyzing a recorded video sequence excluding video backtracking, as if they were live, as a coach. The feasibility conditions of such an experiment led us to study a judo combat by appreciating or estimating the interactions between different criteria as a coach.Method. After training, Masters students (n=12), who specialized in the video analysis and in judo performance, analyzed (they studied three times the same combat) the balance of power (subjective criterion) between two judokas. The process required the student observers to identify whether a judoka was "dominant, i.e.: in a favorable organization to win" or "dominated" whilst managing his/her actions in "programmed/conscious" or "automatic, i.e.: reflex organization" modes. Nonparametric Kolmogorov Smirnov and Wilcoxon tests were used to analyze the data collected by the students.Conclusions. These tests indicated that the analyses were identical and stable at the intra-observer (p=[0.095: 0.999], p=[0.219: 1.0]) and group levels (p=0.224; p=0.406). We propose to include this methodology of analyze in Masters' students training programs and develop these live analyses for coachs, teachers or referees.
