Abstract:
تم التطرق الى مستوى التطور الحاصل في رياضة العاب القوى في فعالية (110 متر حواجز ) نتيجة جهود المختصين باستخدام اساليب تدريبية متقدمة واجراء دراسات علمية مستمرة لهذه الرياضة , وتم التطرق الى اهمية القوة والسرعة والمرونة للاعبي الحواجز وتنوع اساليب التدريب | This included the door on the front and the importance of research : it was addressed to the level of development taking place in the sport of athletics in the effectiveness of (110 meter hurdles) as a result efforts specialists using methods advanced training and scientific studies ongoing for the sport, was addressed to the importance of strength and speed of the players barriers and diversity methods training, as well as the importance aware Albayumikanek in the evolution of sporting achievements, which was the basis of the arrival of global achievements, and the emphasis on the special requirements effective as this is of extreme importance.That the emergence of heroes became the focus of attention of researchers to provide invisible for many in this area.Have resorted aware Albayumikanek to research and investigate the reasons for the success of the athletes and access to the upper levels without the other. Knowing specifications physical attributes of the player ran 110 meters hurdles will be a great help for coaches, especially at the stage of maximum speed in the selection of the important elements that could be the fruit of their efforts and thereby achieved the economy in the time and effort.The research problem : through informed researcher and his field in the sport of athletics and exercise of effective (110 meter hurdles) noted that the lack of information Albayukinmetekih barriers (4 - 5 - 6) at the stage of maximum speed because of their importance in the race and overall achievement and not available in sources and references.These terms enable us to differentiate between good skill and is good through disclosure of real indicators Alatherh in performing step barrier junior.The goals included : - Identify the values of some variables Elkinmetekih in maximum speed phase of the effectiveness of (110 meter hurdles) junior. - Identify Elkinmetekih indicators to step barrier to effective (110 meter hurdles) junior.The imposition of the research : Researcher assumes that some Elkinmetekih variables step barrier is an indication of the stage of maximum speed through knowledge of the differences between the variables Elkinmetekih three barriers (4 - 5 - 6) for juniors.The areas of research : define the following research areas - The human sphere : the players unions Euphrates junior class for ages (16 - 17) years. - Spatial domain : track and field stadium in University Kadsh / College of Physical Education. - The temporal domain : for the duration of the (10/3/2012) _ and very (20/3/2012).Part II : Included theoretical studies and similar, as theoretical studies included three main themes : 1 - aware Albayumikanek divisions and duties.2 - The second axis has do to speed concept and characteristics in addition to the maximum speed.3 - Finally, the third axis which he addressed to previous studies researcher and discussed.Part III : Included research methodology and procedures field where the researcher used the descriptive manner (relations relational) and included research on a sample number was (4) players, and the equipment and tools used in the search, and experience reconnaissance, and experience, key steps conduct a search from filming and testing, and statistical methods.Part IV : Results included and analyzed and discussed on four axes. - 1results values some Elkinmetekih variables step barrier at maximum speed stage and analyzed.2 - Discuss the results of the values of some variables Elkinmetekih step barrier at maximum speed stage junior.3 - to discuss the results is morale among the variables.4 - Results moral debate between variables at three checkpoints (IV - V - VI).Through reached to achieve the objectives of the research and verification of hypothesisPart V : Conclusions and recommendations.This included the door on the conclusions and recommendations reached by the researcher through his studies and came out of the conclusions from them.1 - The distance before inhibitor affect the body's center of gravity height hostility inhibitor.2 - The dramatic rise of the body's center of gravity hostility over inhibitor leads to : - A. Prolonging the flight. B. Low - speed horizontal vessels.3 - The immediate increase the speed values vertical lead to a reduction in the values of speed horizontal vessels.4 - Hostility can acquire horizontal direction relative by prolonging the time to seek before or after the inhibitor.5 - Whenever the distance by a large inhibitor led to be the path of the center of gravity of the body horizontal as much as possible and smooth and be leading man after landing barrier to serve the next run.6. There has been a significant change for three variables before the barrier and the two variables over the barricade.7. Player who has the power, speed and flexibility will lead passing a streamlined manner.Recommendations : The light of the findings obtained from this study and field test procedures circumstances, the researcher developed several recommendations, intended to avoid some of the obstacles, both technical and involving motion analysis and field, which is for research procedures, namely : - 1 - Paying attention to the runners to cut the body's center of gravity above the inhibitor as much as possible since this method of an impact on reducing flight time, and can be done by adjusting certain variables and the most important of which is the distance before inhibitor and fast approaching.2 - The runners to keep as much as possible a slight decrease in their immediate horizontal above the speed inhibitor or beyond, by reducing the values of immediate vertical speed.3 - The distance after inhibitor should not be too large nor too small as it will increase the height of the body's center of gravity over the barricade, and if they are small will be the landing in a right angle or larger and does not serve the running after barrier4 - The achievement ran 110 meters hurdles determined by passing (10 hurdles), so the researcher recommends conducting studies on the largest possible number of barriers - in the case of availability of possibilities - to detect other facts that would add new studies in this direction.5 - Has become very necessary for the coach to analyze the technical aspects of the runners when they pass the barriers, and compare their performance to two or more attempts by cinematography to see and correct the negatives and find out the pros and promotion (this is called feedback).6 - Direct and rapid interest in this segment of the sample, representing the base for the sport of barriers in the future under the supervision of qualified instructors
