Abstract:
احتوى على المقدمة واهمية البحث ؛ اذ تم التطرق فيها الى اهمية الدقة اثناء التهديف، فضلا عن دور العضلات في الاداء المهاري خصوصا عند تنفيذ الركلة الحرة المباشرة، واحتوى ايضا على اهمية استخدام جهاز التخطيط الكهربائي للعضلات (EMG) بلوتوث ومدى فائدته في تح | This chapter contains the introduction and the importance of the research considering the importance of precision during shooting with regard to the role of muscles in skillful performance particularly in doing the direct free kickings. It also consists of the importance of using (EMG) Bluetooth and the range of its benefit in limiting the electric signal for muscles during the practice in addition to the possibility of finding the relationship between physiological pointing during muscles working with the biokinematics variables during direct kicking performance in soccer. * The Problem : The researcher summarizes the problem of research in the study and analysis of all factors which participate in the success of motor performance which is very important for the trainer and player and to those who are so interested in this talent. Recently , it is noticeable that many trainers did not interest to the study of muscles and their relation with the precision of shooting from a biokinematic point of view for its analysis and recognision and finding solutions for them. * The Aims The Study aims at : 1 - Knowing the ruslts of electric activity shapes and some biokinematics variables for kicking leg. 2 - Knowing the nature of relationship between electric activity and biokinematics variables in accordance with the precision of shooting from different places and distance (18, 22m) for direct free kick. * The Hypotheses : It is hypothesized that : 1. There is relationship between electric activity of rectus femoris and adductor longus and the precision of shooting for direct free kicking in soccer from different places. 2. There is relationship between biokinematics variables and precision of shooting for direct free kicking in soccer. Chapter Two : Theoretical Study : This chapter contains the theoretical study which has relationship with the subject. Chapter Three : Study Scheme and its field Procedures : Study scheme includes researcher using descriptive scheme in accordance with study aims. Study data contains three proficinal players in practicing direct free kicking from the players of Altalaba sport club where an experiment was made to know the work of EMG equipment in which many difficulties and obstacles are avoided during the main experiment in which the electric activity is measured for two muscles biokinematics variables. Moreover , precision of shooting is also determed from precision exam.Chapter Four : Displaying , Analyzing and Discussing Results : Electric activity results are displayed for two muscles rectus femoris and adductor long us and from two distances (18m , 22m) and biokinematics variables results are also displayed , in addition to finding to finding the relationship between electric activity variables (time , distance , hight) and the precision shooting , as well as , finding the relationship between biokinematics variables and precision of shooting. Chapter Five : Conclusions And Recommendations : The researcher comes to find many conclusions which consists the following : 1 - There is a difference in work between rectus femoris muscle and adductor long us muscle in kicking the ball from different places. 2 - It is noticeable that making power decrease for kicking leg in producing electric activity when the player becoming older in age and precisely form the left. 3 - Body accumulation variable has an active role in its relation with the precision of shooting from (18.m.). The researcher arrives to some recommendations which are the following : 1 - Making researches with an experimental nature to another sample that consists the same features. 2 - The necessity of recognisition precise time during training course for talent performance to the direct free kick and from different places. 3 - The necessity of using (EMG) equipment for determining the electric signal for more than two muscles in the same time during the use of kicking leg of ball.
