Skill performance and some abilities, bio kinetic function for choosing a football playmaker under 19 years old

Abstract

The method of differentiation analysis is the most important multivariate statistical methods that are used in the processing of metadata and depends on building a function called the differentiation function, which is a linear combination of a set of independent variables that increase the differences between the average groups and thus reduce the error of classification, so the need arose that the process of selecting young players for their football positions in the clubs of Karbala province does not depend on modern methods by taking the opinions of coaches as well as depends on personal experience and not On the objective scientific bases codified in the test and measurement, as well as depending on the player's opinion to play in the position that he likes and tends towards, even if it does not suit his specifications and capabilities, and this leads to the players not being properly employed in the match.

            Through the follow-up of the researcher to the youth category league of Karbala football clubs, and this is in addition to the fact that the researcher has practiced sports as a player, as well as through the researcher's access to a lot of references, studies and personal interviews with specialists, he noticed that there is a disparity in the selection of football players for their positions by coaches, and this in turn leads to the loss of a lot of time and effort with players without reaching the required level. One of the objectives of the research is to identify the discriminatory connotations of skill performance, abilities, biokinetic and visual as a function of choosing a football playmaker under 19 years old. Identify the selection of players as a playmaker in terms of the impact sizes of skill performance and some capabilities, biokinetic and visual, and the research dealt within the theoretical framework everything related to the concept of skill performance and some bio kinetic and visual capabilities. The researcher used the descriptive approach in the survey method (the current situation) as the research community included players clubs of Karbala province for the youth category by (190) players and the exploratory sample was (25) players and the main application sample (70) players, and the fourth chapter included everything related to data processing and reaching scientific results.
