The contribution rate of jump mat variables to the straight spike accuracy index in volleyball among the players of Peshmerga Club.

Abstract

The research aims to identify the values of the variables (jump mat and spike accuracy index) among the research sample, and the relationship between the values of the jump mat variables and the spike accuracy index among the research sample.  Jump Smart with the spike accuracy index among the research sample, and the contribution rate of Jump Smart variable values to the spike accuracy index for the research sample. The researchers used the descriptive method with correlational relationships due to its suitability for the nature of this study. The research community was determined from the players of the Peshmerga Sports Club in volleyball, totaling (17) players. 17 players, and 8 players were selected from the spiking players from the high center numberThe researchers relied on a jump mat to identify (power, force exertion, contact time, jump height, flight time), two video cameras to measure the performance time accuracy of each attempt, and a camera to measure accuracy levels without interfering with the original test. To find the statistical treatments, the researchers used the Statistical Package for the Social Sciences (SPSS) for data processing. The researchers reached the following main conclusions: First, the jump mat indicators studied during the performance of the straight spike in volleyball by the research sample had a high correlation with the accuracy index.Secondly, the variables of the jumping mat significantly contributed to the accuracy index during the performance of the straight smash among the research sample. The researchers recommend emphasizing the development of explosive leg strength to help players reach the highest height, which will assist them in directing the ball during the performance of the straight smash. Additionally, they recommend developing the kinetic speed of the hitting arm among players when performing the straight smash in volleyball within the research sample.
