Sports such as football, basketball, handball, futsal or roller hockey are characterized by taking place in an environment in which two teams compete for the possession of a ball in a limited playing area, for a certain period of time. Each team has simultaneous objectives of scoring through the introduction of the ball into the opponent’s goal or basket and the defense of their own goal from the attacks of the opponents. The team that has scored the highest number of goals (or points) at the end of the assigned time is the winner. The teams that want to improve their sport performance, necessarily should analyse what happens in the games and training from a systemic perspective (Franks and Goodman, 1986). Here, the use of data is becoming essential, but these data, in turn, must be contextualized and qualitatively valued based on the development of the characteristics that emerge from the game itself. For this purpose, the use of video is of great help. Video analysis has become an usual tool for the coaching staffs of the sports teams. There is a high number of programs and solutions that facilitate these work, but, in essence, the audiovisual format allows assessing the team’s performance and how they try to fulfill their objectives. A priori, video analysis provides very rich tactical information, as it allows observing how all the players- a team’s own players and those of the rival- interact in the game, based on the ball, in a physical space during a period of time. But video analysis not only has a practical component (although this is essential), it also provides significant value when it comes to analysing the conditional capacity of athletes and teams, just as it allows medical teams to know how athletes get injured and how they develop in competition and training, which can be very useful when preventing injuries. In the past, these video analysis works had been assigned to audiovisual technicians with little sports vocation. Coaches delegated this function to camera operators or specialized technicians, in the case of the most professional clubs, or subject enthusiasts in the case of more amateur teams. Progressively, this practice has been strongly established in the résumé of all sports coaches, so it has become an key subject of knowledge for any coach, physical trainer, physical therapist, etcetera. But not only that, it evolved until becoming a specialty of the sports coach. The presence of the video analyst is common in professional teams, like the coach, the physical trainer, or the physician. Generally, this activity is assumed by the coaches, who train and specialize in this subject that contributes so greatly to their high-performance teams. In the future, these professionals will have to integrate data analysis to be sport technicians with great specific knowledge of their sport. Audiovisual training and knowledge of sports video analysis software, together with certain competence in mathematics and statistics, will create a professional profile much better prepared for the current period, in which the volume of data is widely available for high performance teams.
