The Effect of Parachute Resistance Training According to the Law of Obstructive Force on Developing Leg Muscle Endurance, Some Biokinematic Variables, and Accuracy of the Smash in Youth Volleyball

Abstract

The importance of the research lies in the researcher's attempt to use parachute training according to the law of obstructive force to develop muscle endurance and some biokinematic variables that constitute an important core of the technical performance of the volleyball smash skill. This is in addition to achieving accuracy in performance by developing leg muscle endurance to reach the highest possible height to hit the ball, thus achieving optimal performance in volleyball. The research problem was based on monitoring developments in volleyball in general, and the development of the smash skill in particular at the global, Arab, and local levels, given its impact on deciding the outcome of a match. Through the researcher's observations, he noted that the technical level of this skill does not align with the developments taking place. There is a significant weakness and fluctuation in the level of performance accuracy among young players. The research objectives are to prepare parachute resistance training according to the law of hindering force to develop muscle endurance, some biokinematic variables, and the accuracy of the smash serve in youth volleyball. The researcher used the experimental method by designing two equivalent groups: control and experimental. The researcher deliberately defined the research community, which is the players of the specialized volleyball center in Al-Shatra district in Dhi Qar Governorate (youth category), aged (16-18) years, totaling (18) players. One of the most important conclusions is the development of the accuracy level of the smash serve skill among the research sample members, based on the differences that appeared in the results of the post-test in favor of the experimental group.
