Abstract
Purpose: to determine the most significant kinematic indicators in the sports selection of beginner shot putters.
 Material and Methods: This study was carried out on a sample of 9 students at the fourth stage of the competition in Division 1, which took place in the 2017/2018 academic year at the Faculty of Physical Education of Maysan University. The following kinematic (biomechanical) parameters were analyzed: the angle of release of the nucleus, the velocity of release, the height of the point of ejection of the nucleus and the speed of swing. The correlation coefficients were determined between the kinematic indicators and the result in the shot put, as well as the regression equation for the dependence of the result in the shot put on the knematic indicators. The data obtained in the study were presented in the form of the arithmetic mean, standard deviation, median, skewness coefficient, Pearson's correlation coefficient, analysis of variance and linear regression, which included the contribution coefficients of each analyzed indicator, standard error, reliability of the regression equation as a whole, and reliability of the coefficients contribution to the shot put result of each kinematic exponent.
 Results. It has been shown that the swing speed has the greatest influence on the result in the shot put among beginner athletes. The swing speed, shot angle, shot speed and shot height have significant relationships with the shot put result. The multiple regression equation for the dependence of the shot put result on the swing speed, shot angle, shot height and shot point turned out to be reliable in general. However, only the swing speed has a reliable coefficient of the regression equation. The shot angle tends to be the determining factor in the shot put result. The release rate and the height of the release point have significant correlations with the shot put result, although in the regression equation they have unreliable indicators of influence on the shot put result.
 Conclusions. When teaching beginner shot putters, the greatest attention should be paid to the pushing swing technique, namely the swing speed. The second most important indicator is the angle of the shot put, it is recommended to use the basic prediction equation, which determines the expected results in the selection of young athletes in shot put, with high reliability of the results obtained. These characteristics are recommended to be used for evaluating young athletes, as well as in the process of training and preparing athletes for competitions.
Highlights
The shot put is a field event in athletics and each of the events has a specific set of features including the characteristics of the implement used, space limitations, and technique requirements which influence the sequence of events and make them unique [1, 2]
In their research [22] defined some of the most important kinematic parameters of the rotational shot put technique. They used a 15segment model of the thrower with 23 defined reference points The results showed that the top result of the throw depends on release velocity, the optimal angle of release, the relation between the rotational motion and acceleration of the final shot, and the angular velocity of the elbow and shoulder joints of the throwing arm
The results of this study suggest that, among elite shot putters, bigger rear knee flexion at rear foot touch-down and release, increased release speed, a more neutral shoulder-hip angle at release and a larger horizontal release distance were the best predictors of the measured distance
Summary
The shot put is a field event in athletics and each of the events has a specific set of features including the characteristics of the implement used (size weight and aerodynamic qualities), space limitations, and technique requirements which influence the sequence of events and make them unique [1, 2]. Research [26] was conducted on the finalists of World Championship to determine the influence of anthropometric and kinematic parameters of the throw (release velocity, release height, release angle) on result successfulness in the shot put. Due to the importance of this weak codification of the training programs applied, competition internationally and its place among other especially those that depend on building their games, especially track and field competitions, the exercises on the mechanical conditions researchers decided to conduct this study, to avoid accompanying the kinetic technical performance of some of the weaknesses of novice athletes in the the thrower, including the peripheral velocity of the future and to enhance and develop the positive joint point of the driving arm of the group and the points, and contribute to the development and basic kinematic variables related to the moment The improvement of the Shot put result. It is worth noting that some basic mechanical aspects must be studied in motion analysis and, optimal release conditions producing a maximum range for a particular athlete can be determined [10]
