تعد المبارزة أحد الألعاب الرياضية التي يتأثر فيها الأداء بتطور القدرات الخاصة بالأداء ومنها تحمل (سرعة وقوة الأداء ),وأن أكثر الأساليب السابقة في تدريب تطوير تحمل(سرعة وقوة الأداء) بالمبارزة تكون على ارض صلبة مثل الخشب والألمنيوم آو الإسفلت وفي بعض القاعات يكون التارتان, وظل هذا الأسلوب لفترات طويلة في العراق ،حيث تستخدم تدريبات الإثقال التي تعمل على تنمية تحمل القوة . أما في الوقت الحاضر فقد ظهر اتجاه حديث في التدريب ,إذ نرى لاعبي كرة القدم لريال مدريد يؤدون تدريباتهم على الرمال الشاطئية بعد ثمان دقائق من تدريبات الإحماء والركض, ومن خواص التدريب على الرمل جعل مقاومة وزن الجسم أثقل لانغماس الرجل في الرمل مما يعطي مقاومة اكبر للجسم . و تكمن أهمية البحث من خلال الاطلاع على كثير من الدراسات والبحوث قد ثبت أن تطور القدرات الخاصة على اليابسة تؤدي إلى نتائج جيدة ،وكذلك نفس المجال بالنسبة لتدريباتها على الرمل . لذا هدفت الدراسة إلى التعرف على أي الأسلوبين أكثر فاعلية في تطوير تحمل( سرعة وقوة الأداء) بالمبارزة. واستخدم المنهج التجريبي على لاعبي منتخب شباب البصرة بالمبارزة والبالغ عددهم ( 12) لاعباً , وقسمت عينة البحث بالطريقة العشوائية إلى مجموعتين, حيث كانت المجموعة الأولى التجريبية(6 لاعبين) يتدربون باستخدام أسلوب التدريب بالمقاومات على الرمل , بينما كانت المجموعة الثانية الضابطة (6لاعبين) يتدربون باستخدام أسلوب التدريب بالمقاومات على الأرض (داخل القاعة الرياضية وكانت أرضيتها من الإسفلت (صب). وبعد الانتهاء من تطبيق المنهاج التدريبي باستخدام تدريبات المقاومة بوزن الجسم والإثقال الخفيفة على الأرض في القاعة الرياضية والتدريبات على الرمل تم تحويل البيانات إلى جداول. و لغرض اختبار الفرضية المتعلقة بدلالة الفروق بين الاختبارات القبلية والبعدية تم استخدام اختبار ( ت ) للعينات المترابطة. فاستنتجت الباحثة :وجود فروق معنوية بين المجموعة التي تدربت على أرضية القاعة ( الإسفلت) وبين المجموعة التي تدربت على الرمل ولصالح المجموعة التي تدربت على الرمل . وتوصي باستخدام التدريبات على الرمل لما لها من اثر ايجابي في تطوير تحمل (سرعة وقوة الأداء بالمبارزة ).
Abstract
This study was to demonstrate the role-use planning scientific methods is disabled and little used in the planning and follow-up construction of vital projects in the province of Baghdad, including network planning methods, in order to find the optimal time to finish the project in light of the resources available and the budget set for it, in the current research has been used the most prominent network planning methods and two stylistic (CPM / PERT), was the application of the critical path method on standard-design school project (traditional) to draw Action Network according to confirmed times for the activities of the project and account his Crashing time , It was Pert technique applied to the project hemato

The aim of the study is to study the relationship between strategic orientation and organizational performance. The strategic direction is the main purpose for which the organization is found. Therefore, it is the main engine for all the activities and tasks that the institution can carry out to achieve its objectives within the environment in which it operates. ,. The research problem was formed by several questions to determine the level of the strategic direction and the nature of its relationship with organizational performance in the Iraqi Ministry of Defense / Inspector General's Office as the field of application to answer. The sample was selected by a sample of 60 individuals, department managers, And the que
The present work includes a design and characteristics study of a controlling the wavelength of high power diode laser by thermoelectric cooler [TEC] . The work includes the operation of the [TEC] to control the temperature of the diode laser between ( 0- +30) °C by changing the resistance of thermistor. We can control a limited temperature of a diode laser by changing the phase cooling between hot and cold faces of the diode, this process can be attempted by comparator type [LM –311] .The theoretical results give a model for controlling the temperature with, the suitable wavelength.
The organizational culture is an effective control mechanism that dictates the behavior of employees and according to their intellectual and social orientations, so it is considered a more powerful way to control employee orientations and determine their management according to organizational rules and regulations, as it was one of the most important factors determining the performance of organizations, while organizational performance is a measure of what the organization has achieved from the objectives of the scheme To ensure that it faces various changes and remains within the global competition, and to reach that it was necessary to identify the most prominent and most important research problems in knowing the extent of com

To investigate the impact of different concentrations of glycol on the performance of a diesel engine, an experimental water-cooled four-stroke motor was utilized, with oil containing 0, 100, and 200 parts per million (ppm). Specific fuel consumption, thermal efficiency, friction power, and exhaust gas temperature were examined as performance indicators. To compare the significance of the treatments, the study employed a full randomization design (CRD), with three replicates for each treatment at th

The primary objective of current study was to evaluate the effects of different anastrozole dosages on the physiological performance, hematological profile, and serum biochemical parameters of broiler roosters. A total of Twenty-six Lohmann Brown roosters were randomly assigned to four treatment groups. The first group (T1) served as the control and received no anastrozole, while the other groups (T2, T3, and T4) were administered 0.2 mg, 0.4 mg, and 0.6 mg of anastrozole per day, respectively. The first and second groups consisted of six birds each, while the third and fourth groups had seven. The results demonstrated a significant improvement (P ≤ 0.05) in several physiological and biochemical parameters in the group receiving 0.6 mg of
