The Effect of Special Exercises on Developing Maximum Lower Limb Strength and Accuracy of Some Crushing Techniques in Volleyball Players (Advanced) in the Kurdistan Region

Abstract

The research aims at developing a set of specific exercises to develop maximum lower limb strength and accuracy of some crushing attack techniques in volleyball, and to identify the differences between the results of pre- and post-tests in developing maximum lower limb strength and accuracy of some crushing attack techniques in volleyball. The researcher assumes the existence of differences between the results of pre- and post-tests in developing maximum lower limb strength and accuracy of some crushing attack techniques in volleyball. The researcher used the experimental method with a single-group design with pre- and post-tests to suit the nature of the problem. The researcher deliberately selected the research community (stratified), which comprised (120) advanced volleyball club players, at a rate of (12) players per club for the 2024 sports season. The research sample included the Taq Club. The sports method and the number of sample members was (12) players and the coefficients of reliability, validity and objectivity of the tests were found. Pre-tests (for physical abilities) were conducted, and the researcher prepared special exercises within the framework of the training curriculum for the special preparation stage and the post-tests were conducted after completing the application of the special exercises. The researcher used the statistical program (SPSS) to process the data statistically and after presenting, analyzing, and discussing the results, the researcher reached the following conclusions: The training curriculum used contributed to the development of the maximum strength of the lower extremities. The maximum strength is related to the accuracy of performing the smash skill in volleyball. Also, the special exercises used within the framework of the training curriculum have a positive impact on developing the maximum strength of the lower extremities and the accuracy of some smash attack methods in volleyball.
