Rp-Trainings Impact of Proprioceptor Neuromuscular and Ballism Facilitation on Power Balance Influence of Airless Training with Unbalanced Devices in A

Abstract
The current research aims at preparing airless trainings with unbalanced devices in volleyball for players under 17 years and knowing the Influence of airless training with unbalanced devices in airless abilities and some bio kinetic capabilities and indicator of accuracy of the two beats, the forward and backward in volleyball for players under 17 years.
The researcher hypothesized that there are positive individual differences between the anterior and posterior tests for the experimental and controlled groups for the benefit of the posterior test in the airless abilities and some bio kinetic capabilities and indicator of accuracy of the two beats, the forward and backward in volleyball for players under 17 years and there are positive differences in the posterior tests for the experimental and controlled groups for the benefit of the experimental group in airless abilities and some bio kinetic capabilities and indicator of accuracy of the two beats, the forward and backward in volleyball for players under 17 years. The researcher adopted the experimental approach by designing the two equivalent groups ( the experimental and the controlled) with the anterior and posterior tests for its suitability with the nature of the problem when the research community was limited with players of Durat Kerbala academy in volleyball ages under 17 years. The researcher chose sample of his study in the simple random observation. The researcher chose the research sample of the investigated variables with 20 players around 77% out of the total origin community. Then, they were divided equally randomly into two groups, each group has 10 players. Later, the work started with the main group of the research sample on Saturday 13/ 11/ 2021 and ended on Wednesday 5/1/ 2022 on the research sample. The researcher’s work was limited in a portion of the main part of the training unit about( 39-40) minutes out of the scientific preparation period. After ending the main experiment, the posterior test on the research sample was don and it was occurred under the same situations and conditions in which anterior tests were occurred on Saturday and Sunday 8-9/ 1/ 2022 when the researcher used the electronic computer in taking out the test results by statistical package for the social sciences ( spss) to carry out the following statistical devices (Arithmetic mean, Standard deviation, Pearson Correlation coefficient, ( T) for the interrelated and dependent samples, chi square, Liven law ). Later, a detailed display for all results of anterior and posterior tests used in the study for the research sample. These results were analyzed in the light of the statistical laws used in the research which were suitable for these data in accord with fixed scientific references of this use to be able to achieve aims and prove the research hypotheses in the light of the applied experimental procedures that the researcher did to reach these results. Then, they were discussed in the light of its referential framework. The researcher concluded some of the following results as airless training with unbalanced devices have clear influence in developing the airless abilities ( the high airless ability and the airless power) and some bio kinetic capabilities ( response speed, balance, and harmony), indicator of accuracy of the two beats, the forward and backward in volleyball. The use of unbalanced devices highly contribute in adding interest and anxiety factor and increasing players’ interest for training. The most important recommendation that the researcher suggests is using of airless trainings with unbalanced devices in the different academies as a helper training course and implying it within the special trainings, attempting airless trainings with unbalanced devices on other age categories, and making airless trainings with unbalanced devices in order to use it in studying variables in other sports.
