The effect of special exercises in developing the values of some bio kinematics variables and physical abilities of the accuracy of the crushing transmission skill in volleyball (Misan players 20-25 years old)

Abstract

The importance of research is reflected in the preparation of strength exercises according to scientific and objective foundations that contribute to improving the level of technical performance of the skill of overwhelming transmission in volleyball by upgrading the values bio kinematics and physical variables, which ultimately constitute the general form of the skill and thus reach the best performance in the game of volleyball. Reaching the higher levels is one of the important matters that requires knowledge of the most important mechanical foundations for the angles of muscular work, which contribute to mastering the skill by relying on kinetic analysis as a logical means by which the phenomenon is evaluated objectively to determine the most important areas of strength and weakness for the level of performance of applicants, Missan Governorate. As for the research problem, it lies in not using modern scientific training methods to develop the skill of overwhelming transmission through the process of linking the physical and mechanical side to improve the motor path of the skill, which led to a decline in the level of technical performance of the skill of overwhelming transmission in volleyball, so the use of special strength exercises according to a correct scientific approach It has a great benefit because it is moving towards the correct motor path, thus developing the physical, mechanical, skill and cognitive aspects alike. It is to identify the effect of the explosive The explosive power of the arms and the speed characteristic of the legs on the values of some bio kinematic and physical variables and the accuracy of the performance of the skill of overwhelming transmission in volleyball for the applicants of Missan. As for the researcher’s hypothesis: There are significant differences in the values of some bio kinematics and physical variables and the accuracy of the performance of the crushing transmission skill between the control and experimental groups and in favor of the experimental group. A training unit at a rate of (3) training units per week, as the researcher chose his research community in a deliberate way, and they are the applicants of Maysan Governorate in volleyball for the 2022/2023 season, numbering (15) players, which constitutes (80%) of the original community divided into an experimental group (6)) And a control group (6) players, and (3) players a reconnaissance experiment, and (6) attempts were given to all members of the sample, and the attempts were photographed by a US-made mobile device iPhone 11 pro max (240) images per second, number (3), And RAM 4 GB. The researcher also used the Kenova program to analyze the attempts and extract the values of the bio kinematics variables. The researcher concluded: that special strength exercises have developed from the values of bio kinematics and physical variables in the post-test of the experimental group as a result of using exercises similar to the motor path of the skill of crushing serve. Field tests procedures for the special physical abilities of explosive, great and maximum ability, in addition to conducting experiments on other offensive skills for the same specialized effectiveness.
