Abstract:
ضم هذا الباب المقدمة واهمية البحث التي تطرقت فيها الى رياضة الجمناستك الفني، ودور العلوم الطبيعية الاخرى في تطورها ومن ضمنها علم التدريب وعلم البايوميكانيك من خلال توظيف هذه العلوم في تطوير مستوى الاداء الفني فيها، فللاداء الحصة الاكبر من الدرجة الاجمال | The study included the following five chapters : Chapter one : which included the study definition This chapter involved the introduction and the importance of the research in which we have dealt with artistic gymnastics , and the role of other natural sciences such as training science , biomechanics throughout using such sciences in developing the level of technical performance. Performance has the majority of the total scores which form the bodily movements in gymnastics , thus performance is given (10 marks) of the total final mark. The jumping springboard is one of the important devices for men's artistic gymnastics , at which skills pass through many stages including ( the approach run stage , striking of rising board stage , first flight stage , lean on hand stage , second flight stage , and landing stage). These stages are connected to each other , and success of each one depends upon the success of preceding stage , and all stages depend on the success of the first stage which is the approach run. The importance of approach run resides in the obtaining of the player the necessary and regular acceleration to get the horizontal velocity (kinetic energy) , whose speed fits to the performed difficult jump and converting it to (potential energy) at the moment of striking the rising board , and then converting it to vertical velocity after gaining kinetic energy with suitable acceleration , so as to convert it from one type to another without any decrease , in order to achieve the best artistic performance of the performed jump , because speed fluctuation will negatively and continuously affect the quality of jump performance. Therefore , the importance of this study resides in knowing some biokinmatic variables of the approach run and revealing weak points and defect in this run , and then setting up exercises to improve it , avoiding mistakes and identifying the scope of the effect of these exercises on the run. Since these exercises are considered as corrective and developmental program which can help to treat the weak points of performance and conquer them to improve the artistic performance. However , the research's problem can be summarized in weak artistic performance of some gymnastic skills on springboard device , which will result in low mark scoring by the players , and that is due to the fluctuation of the approach run , which created a problem affecting the kinetic pathway of the skill , and this in turn will lead to artistic performance score deduction , and therefore it will affect the final mark of the player. The aims of the study were as follows : Prepare exercises to improve the approach run in accordance with some biokinmatic variables.Identifying the values of some biokinmatic variables of the approach run and the values of performing some skills on the springboard.Identifying the effects of exercises used within a proposed training program to improve some biokinmatic variables of the approach run and the values of performing some skills on the springboard.The hypothesis of the study were as follows : There were statistically significant variation in some biokinmatic variables of the approach run between the pre and post tests.There were statistically significant variation in the results of performing some skills on the springboard between the pre and post tests.The domains of the study included the following : Human domain : included the players of the national juvenile selection team in artistic gymnastic who were 6 players , with age range (11 - 13) years.Temporal domain : The experimental program started from 22/5/2014 to 28/8/2014.Spatial domain : at the training center of the national selective team in artistic gymnastic in Zayoona qurter.Chapter two : Theoretical and similar studies : In this chapter , the researcher studied the theoretical studies related to her study , including the gymnastic and it's importance , and the concept of biomechanics and different types of biokinmatic analysis. The researcher also mentioned the modern springboard , it's properties , measurements , the natures of performance , description of exercise on the spring board , the artistic , biokinmatic , and legal basis of the approach run and skills. Finally , the researcher involved similar studies which are related to the present one with their discussion.Chapter three : Methodology and field procedures of the research : This chapter included the methods used by the researcher , which is the experimental methods of single experimental group , the exercises of the approach run with it's scientific basis , the biokinmatic variables used in the research and methods of their derivation , as well as the explorative experiments related to the proposed experiment and method. The exercise program started on 22/5/2014 till 28/8/2014 and it's application lasted for (12) weeks in as much as 3 exercise units per week on (Sunday , Tuesday , and Thursday) i.e the total exercise units were (36) during the research period. The researcher assigned (35) minutes for each exercise unit. The results were treated by suitable statistical methods through the statistical program (SPSS) in order to recognize the development of artistic performance level of the selected research skills.Chapter four : Review , analysis and discussion of the resultsThis chapter involved review and analysis of the results throughout tables and appropriate graphical figures with their scientific discussion depending upon scientific references that supported the findings of the researcher , thereby , the researcher achieved the aims and hypothesis of the study.Chapter four : Conclusions and RecommendationsThe researcher has got the following conclusions : 1 - The results showed efficacy of using exercise to improve the approach run within the proposed exercise method , which is set in accordance with some biokinmatic variables to develop the artistic performance of some skills on the springboard.2 - The results revealed efficacy of using the approach run exercises to improve biokinmatic variables of some skills in the study.The researcher recommended the following points : 1 - Generalization of the exercise methods proposed by the researcher to improve the approach run in accordance with some biokinmatic variables to perform some skills on the springboard at the training centers of gymnastic in Iraq. 2 - Reliance on modern technology to analyse skills in gymnastic to detect weakness and strength points during the kinetic pathway of the skill so as to avoid the weakness point and confirm strength points by using video recorders.3 - Performing similar studies and researches of other skills in gymnastic using different devices , including different biokinmatic aspects for boys and girls.
