The Effect of Specific Exercises on the Speed of Motor Response and Accuracy of Receiving Service for Secondary School Students of Volleyball

Abstract

As for the research goals, they focused on developing specific exercises to develop the speed of the kinematic
response and the accuracy of receiving service of volleyball, and to know the effect of these exercises in
developing the speed of motor response and the accuracy of the receiving service for students of volleyball,
this research was conducted on a sample of (12) medium-fat students, who were divided into two equal
groups, one experimental and the other control, each group consisting of (6) students, after conducting
the processes of homogeneity and parity, The appropriate tests for this skill were also chosen, with an
exploratory experiment conducted on a group of medium-fat volleyball students from outside the basic
research sample with the use of tools and aids in the research, pre-tests were conducted on the two groups,
and then the vocabulary of specific exercises was applied within the educational units of (16) educational
units. The time of each unit is (90) minutes by two units per week, the share of exercises within the main
section of the educational unit was (30) minutes, the end of the educational units for this skill, the post
tests were taken, and then treating the results of the research using appropriate statistical means. The two
researchers came up with several conclusions, the most important of which was that the vocabulary of the
specific exercises that were used had a positive effect on developing the speed of motor response and the
accuracy of receiving service e volleyball.
