Abstract:
تطرق الباحث في الباب الاول الى اهمية التمرينات البصرية والتدريب البصري في تطوير قدرات اللاعب على تحقيق افضل مستوى من خلال تطوير قابليته على ادراك المتغيرات المتعددة المحيطة به اثناء المباراة والقدرة على التصرف بسرعة ودقة لاداء الواجب الحركي، فضلا عن فتح | In chapter one , the researcherdealt withthe importance of visual exercises and visual training in the development of player's capacity to achieve the best level through developing his/her ability to realize the multiple variables surrounding him /her during the game.Also the ability to act quickly and accurately in the performance of duty motor, as well as opening up new areas for novice applied research to identify the benefits of regular physical activity and practicing visual exercises orderly to develop the capabilities of the player's visual and cognitive work in turn on the development of accurate performance.The study problem lies in the lack of coaches' interestsdue to insertvisual exercises in the planning of the training modules, similar to physical and skills exercises to develop players' ability to be awareof their surroundings from different visual variables during the game, which will reflect negatively on the accuracy of their performance and the ability to choose the exact response required for duty motor performance on the one hand, while on the other hand, the researcher noted weakness in the accuracy of skills performance in current research.The current study aims at : 1. Preparing visual display exercisein volleyball for youth. 2. Identifying the effectof optical vision exercises in the development of surrounding areas perception in basic volleyball skills for youth.3. Identifying the effectof optical vision exercises in the development of some motor skills in basic volleyball skills for youth.4. Identifying the effectof optical vision exercises in performance accuracy of the basic volleyball skills for youth.The research hypotheses are; 1. There are statistically significant differences between pre and posttests in the surroundingareas perceptionin favor of posttest.2. There are statistically significant differences between pre and posttests in some motor abilities and in favor of posttests. 3. There are statistically significant differences between pre and posttests in performance accuracy of basic skills and in favor of posttests. In chapter two, the researcher tackled withvision and its relationship to motor performance and optical vision and its importance in the field of sports as well as the factors that must be met for the vision process and visual training, and then the realization of the surrounding areas and its main variables which included the visual field and the focusing power of vision , then the spilt - attention, emotional maturity, time reaction, motor capacitieslike fitness, compatibility and volleyball basic skills representing by;serving, setting, and blocking as well as studies related to the currentstudy. In the third chapter, the researcher used the experimental design in accordance with the suitability of the study problem and aims. The study sample consisted of youth volleyball players at Diyala province , the number of players are (16) of the season 2013 - 2014 who were intentionally selected, (3) players were excluded to conduct the three pilot studies, the final total of the sample was (13) players, the researcher conducted their homogeneity and equivalence , then the researcher deliberately determined the most important motor and basic skills to conduct the study and prepare optical vision exercises and exposing then to the experts in volleyball game and then testifying the pre - tests and after application optical vision exercises in the current study sample within training approach for (8) weeks, in the amount three units per week , in order to be (24) unit training, then the researcher conducted the tests under the same conditions of the pre - tests, as well as the use of appropriate statistical methods for data processing that have been obtained. In chapter five, the researcher deliberately researcher showed ,analyzed and discussed the results after statistically treatment, and then display the data in tables and graphs, the results indicate that there are statistically significant differences between pretest and posttest for the study sample in variables of surrounding areas perception, some motor skills and accuracy performance of basic skills and this is what achieved thestudy hypotheses and aims. The most important conclusions are : 1. The optical vision exercises havea positive effect on the development of awareness of the surrounding areas for young players in volleyball. 2. The optical vision exercises have a positive effect on the development of some motor skills (fitness and compatibility) for young players in volleyball. 3. The optical vision exercises havea positive effect on the development of some basic skills (serving, setting, and blocking) for young players in volleyball. The most important recommendationsare ;1. The need to apply the optical vision exercises on young players in volleyball2. The need to focus on activating the role of optical vision exercises to improve the basic skills in volleyball.3. The useof modern tools of modern sports equipment that depend on the improvement and development of visual abilities for players.
