تتطلب كرة القدم الحديثة تطوير الصفات البدنية والمهارية للوصول باللاعب إلى لمستويات العليا، ولما كانت هذه الصفات مرتبطة مع بعضها البعض، فانها تتطلب ان يتم تطويرها معا في نفس الوقت دون تنمية كل صفة على حده، وإن توافر الحد الأدنى من الصفات البدنية كمتطلبات أساسية للأداء المهاري يعتبر الهدف الأساسي للتخطيط لأي برنامج تدريبي، وإن الصفات البدنية لها مفهوم شاسع وواسع الاستعمال في مجال البحوث الرياضية، وقد أعطيت عدة تعاريف لها ( القدرة البدنية – اللياقة البدنية – الكفاءة البدنية )، وأن التدريب البليومتري Plyometric Training يعد من أهم الأساليب التدريبية لتطوير القدرة العضلية وتحسين السرعة في العديد من الأنشطة الرياضية والتي تتطلب دمج أقصى قوة مع أقصى سرعة للعضلة حيث يساهم هذا الأسلوب في التغلب على العديد من المشكلات التي تقابل القدرة فيما يرتبط بالعلاقة بين القوة والسرعة، واصبح واضحا انه لابد من توفر المعلومات لدى المدرب عن الخصائص اللازمة لأداء المهارات المختلفة حيث اسهم التطور التكنولوجي في مجال التحليل الميكانيكي في الكشف عن العلاقات المتداخلة بين حركة اجزاء الجسم اثناء تأدية تلك المهارات والتي لايمكن الحصول عليها الا بمتابعة وتحليل حركة اللاعب اثناء مراحل اداء هذه المهارات، وان تطور المجال الرياضي مثله مثل كثير من مجالات النشاط الانساني قائم على تطور العلم ودقة المعلومات، فبدون المعلومات الدقيقة لن يستطيع الرياضي ان يتفاعل مع مدربه اثناء التدريب للوصول بالأداء الى المستوى المطلوب، وعلى الرغم من أن بحوث كرة القدم واسعة النطاق، إلا أن البحوث المتعلقة بمهارة الركلة بباطن القدم من علامة الجزاء وبيوميكانيكية حركاتها تعتبر قليلة اذا ماقورنت مع بقية البحوث المتعلقة بالجوانب الاخرى لكرة القدم، وهكذا فإنه يبدو مناسبا للبحث في مهارة الركلة من علامة الجزاء بمزيد من التفصيل، حيث تعتبر هذه المهارة من المهارات الأساسية التي تحتم على لاعبي كرة القدم في مختلف المستويات إتقانها لما لها من تأثير مباشر على تغيير نتائج المباريات وخاصة في حالة التعادل واللجوء الى تطبيق نظام الركلات الترجيحية ، وبالرغم من اهمية اتقان مهارة التصويب ( الركلة من علامة الجزاء) إلّا إنه مازال كثير من لاعبي كرة القدم يخفقون في التصويب، وقد يرجع ذالك الى وجود قصور في عملية تحسين أداء هذه المهارة الهامة، في حين إن طبيعة المباراة تستدعي من اللاعب القيام بالأداء المهاري بقوة وسرعة ودقة ، ولقد اتفق العديد من الباحثين على ضرورة تدريب جميع اللاعبين بما فيهم حارس المرمى على اداء ركلات الجزاء وإن اللاعب الذي يتقن اداء الركلة من علامة الجزاء هو من اهم اللاعبين بسبب اعتماد الفريق عليه في الاوقات الحرجة والمواقف الصعبة التي تتطلب منه اداء تلك المهارة بشكل اقرب مايكون للمثالية, حيث يتطلب ذلك استخدام تدريبات حديثة وخاصة ذات مستوى عالي ، ومن هنا تبلورت مشكلة البحث في وضع تدريبات بليومترية وفقا لبعض المتغيرات البيوميكانيكية والعـضلية لتحسين اداء الركلة من علامة الجزاء في كرة القدم، لتوجيه وتطوير العملية التدريبية وألإرتقاء باللاعب وإيصاله الى مستوى عال من الاداء.
It is a common Knowledge that adverbs in Turkish languages can modify verbs, adjectives, nouns or other adverbs. Moreover, adverbs can determine the meanings of nouns and verbs in a sentence as far as time, place, manner, quantity and interrogative are concerned. The present study debates adverbs’ functions in Namiq Kamal’s play Vatan yahut Silistre.

Therefore, this study was conducted to investigate the association of leukocyte telomere length (LTL) with the presence of higher body weight in middle-aged females and males. The study subjects comprised 160 (80 control and 80 higher body mass index BMI groups) with ranging ages of 30-50 years included and stratified for BMI. The physio-biochemical analysis was measured using enzymatic determination. Mean telomere length was determined by using the southern blotting technique. The association analysis revealed a significant variance (P < 0.01) in biochemical parameters between higher BMI grou

Show MoreThe objective of this study is to determine the sources of growth of the cement industry in Iraq for the period 1990-2014 and to indicate the nature of the technological progress used in it. To achieve this objective we have built an econometric model, by adapting the production function constant elasticity for substitution, using multiple regression, and enforcement, SPSS program, and using the ordinary least squares method (OLS). The results showed that quantitative factors (labour and capital) are the main sources of growth the cement industry in Iraq, and the qualitative factors (technological progress) did not contribute effectively to achieve this growth. And that the production techniques adopted in the cement industry in
