Impact of a proposed program to develop streamlined performance and Accuracy sweeping serve skill

Abstract

The use of standardized exercises according to a proposed program is a modern method that can develop the streamlined performance in terms of (speed - time) and develop some biochemical variables according to the performance of the sweeping serve skill, Research objective, Identify the proposed program using different exercises, identify the impact of the proposed program to develop some biomechanical variables and the streamlined performance in terms of (speed - time), and its impact on developing the accuracy of the skill of sweeping serve volleyball for advanced players, There are statistically significant differences in some biomechenical variables, and the accuracy of the sweeping serve skill, The researcher used the experimental method on a sample of (24) players representing the total research community the research was applied to a sample of (12) players from the Army and Police Sports Club, pre and post tests were conducted.

The researcher concluded that it is necessary to pay attention to the skillful and physical performance of all skills, and to pay attention to the bio-mechanical variables and the fluidity of movement to reach the highest levels, Separate and continuous momentary strength exercises and their impact on kinetic energy and force moments of some muscles of the two legs and the accuracy of the skills of the sweeping serve, diagonal and straight hitting in volleyball.
