Complex exercises according to the data of smart monitoring devices and their impact on some physical abilities, biomechanical variables and scoring accuracy for young football players

Abstract
The idea of using smart monitoring devices to prepare special training for most sporting events has become a modern scientific matter that must be pursued by most teams that seek to advance at sporting levels and obtain great achievements in most sports, especially the popular games, including football. Modern technical devices are among the most important means that help develop the technical skills of the players, especially if they are worked on by specialized trainers who have advanced field and scientific experience, such as the technical sports monitoring devices developed by many sports companies specialized in sports equipment.
The importance of the current study lies in the possibility of determining the strengths and weaknesses of young football players in the special physical abilities and some mechanical variables, and developing exercises that help improve the level of these physical abilities and the path of mechanical variables in terms of strength and speed of some parts of the player’s body in order to serve the main goal, which is to develop the level of scoring skill For football as well as the importance of theoretical frameworks for the variables concerned with study and research of special physical abilities and mechanical variables affecting the accuracy of scoring.
The researcher has used modern techniques in youth football training and the importance of analyzing their data to legalize football training and obtain the required development in physical abilities and biomechanical variables to contribute to raising the level of our youth teams with the skill of football scoring and developing it and comparing the smart methodology with the traditional methodology, the method of training players in it, and enhancing the values of During the game, design the parts of the training unit and the characteristics of each part, and the objectives of the exercises.
The researcher used the experimental research method by designing the two equal groups (control and experimental) with pre and post measurement, which he deems consistent with the specifications of his research and the achievement of the objectives of his study.
The research community included the young football players in Al-Kut Club in Wasit Governorate, who numbered (24) players within the first division league for the sports season 2020-2021.
The researcher prepared a set of exercises to develop the skill of soccer scoring and applied it to his research sample within (24) training units and at a rate of three units each week in which he chose Saturdays, Mondays and Wednesdays, which were conducted in the assistant stadium at the Kut Olympic Stadium.
The researcher reached several conclusions, which are as follows:
1. The researcher’s use of scientific tools, including the smart ball, helped in providing accurate information on the players’ levels that contributed to organizing appropriate training vocabulary, which achieved positive results.
2. Training using smart devices has an effect on improving the sense of ball speed when performing the direct free kick skill.
3. The development of the ball’s rotational speed, which indicates the players’ control of the force and the point of its impact on the ball through the use of smart ball exercises.
4. An evolution occurred in the linear velocities of the knee, ankle and foot joints as a result of the development of force for the thigh and leg muscles using resistances
