Markers of the movement of football players in the assessment technical and tactical potential

Relevance. Significant changes there have been in the organization of the training process of youth professional sports in recent decades. The problem of current control and monitoring in the preparation of sports reserves, in particular in football, has become clear and obvious. An important aspect of a rational learning and training strategy is the technological effectiveness and digitalization of the process. Global positioning systems (GPS) with excellent data portability provide reliable and valid tracking of the player and are used widely in practice by coaches, analysts and scientists in the field of sports. The large amount of digital information collected by GPS technologies enables to see in a general array of information the process of training sessions and competitive games in team sports. The analysis of the position, speed and nature of the method movement of players on the football field creates new opportunities for assessing the technical and tactical qualification of players. The search for informative mechanical characteristics that predict the success of the game arouse scientific interest. Goal. The goal is to establish the spatial and temporal characteristics of the movement of football players, using the global positioning system (GPS) as markers of the effectiveness of playing activities, focusing on the expert assessment of the implementation of technical and tactical readiness in competitive activities. Methods. GPS system for global positioning Catapult (Optimeye S5, Catapult Innovations of Australia, Melbourne) was used in 20 official football matches. The company developer provides access to the cloud-based analytics platform OpenField for data processing and storage. Results. In youth football it is proposed to use GPS parameters (which have the most impact on the success of the technical and tactical potential of athletes specializing in football): total duration, min (total duration, min); meter in the speed zone 4.5-5.5 m/s (speed zone 4.5-5.5 m/s, m); meter in the speed zone > 7 m/s (speed zone > 7 m/s, m); inertial braking/deceleration, number (IMA decal, amount). Multiple regression analysis confirmed reliability and informativeness of them. Conclusion. The practical necessity of current diagnostics and scientific and methodological interpretation of the mechanical characteristics of motor activity contributes to the development of a rational strategy for training and competitive activities, the formation of optimal physical conditions and the prediction of overtraining of football players.
