Indicators of Physical Fitness in Football Players of Different Playing Positions

Abstract

The study presents a comprehensive theoretical and empirical substantiation of the parameters of physical fitness in youth football players, taking into account their playing positions. It reveals the differentiated dynamics of development in key motor qualities that determine the effectiveness of competitive performance in modern football. It is argued that inter-positional differences in physical characteristics are conditioned by the functional demands specific to each playing role, necessitating the individualization of the training process. The aim of the study was to identify the specific manifestations of physical qualities among football players of different playing positions based on the results of comprehensive testing. The object of the study was the physical fitness of youth football players. To achieve the stated aim and solve the research tasks, the following methods were used: analysis and synthesis of scientific and methodological literature; pedagogical observation; physical fitness testing; and methods of mathematical statistics. At the ascertaining stage of the experiment, a comprehensive testing protocol was conducted, including indicators of starting speed, speed-strength and coordination abilities, as well as endurance. The results showed that forwards demonstrated superiority in short sprint performance and jump exercises; midfielders showed higher values in functional endurance (Yo-Yo test); and defenders excelled in strength-endurance tasks and direction-changing exercises. The effectiveness of using an integrative testing system for stratifying players by physical profile and constructing individualized development trajectories was substantiated. A conceptual approach was proposed to optimize the training process based on the targeted selection of test indicators relevant to the functional demands of each playing role. The research findings can be integrated into the training of youth footballers, educational programs in sports universities, and into practical planning of training loads, taking into account the morphofunctional heterogeneity of the athlete population.
