Functional characteristics of playing roles of the tactical model "4: 3:3" in youth professional football

Relevance. In modern professional youth football, the functional status of a player is determined not only by his role, but also by the chosen tactical model. Diverse tactical constructions of the team's game form game variability, creating new role distributions and functions of players of different roles on the field. Due to the peculiarities of the motor activity of football players in the implementation of tactical and technical readiness within the framework of the implemented model of the organization of team play, there is a need for a detailed study of the functional characteristics describing a specific playing position. The purpose of the study. To determine the distinctive features of the functional characteristics of football players of various playing roles when the team implements the tactical scheme 433 during the game. Research methods. 56 football players were examined in 15 official football matches using modern sports technologies the Catapult GPS system (Australia), Polar chest monitors H10 (Finland) and the Omega-Sport hardware and software complex of Dynamics (Russia). The results of the study. Based on the data, significant indicators were established training impulse (TRIMP, standard units), speed zone 4,-5.5 ms, number of meters (speed zone 4.5-5.5 ms, m), speed zone 7 ms, number of meters (speed zone 7 ms, m), inertial high-intensity braking deceleration, number of times (IMA deceleration, number). Based on the criterion, Tukey found significant (p0.05) paired differences between playing roles (forwards, extreme forwards, central midfielders, extreme and central defenders) in the established significant indicators. Conclusions. The greatest energy consumption, determined by cardiac activity, is observed in central midfielders, as well as the greatest distance in the speed zone of 4.5-5.5 m s. The playing roles of the attack zones (central and extreme) and defense zones (central and extreme) differ in motor activity of a predominantly eccentric nature and motor function of maximum power.
