لعبة كرة السلة واحدة من الألعاب الجماعية التي تتميز بقوة وسرعة الأداء في المباريات، وهذا لم يأتي مصادفة وإنما جاء نتيجة لتطور العملية التدريبية من جانب ومن جانب آخر امتلاك اللاعبين لقدرات بدنية لها فاعليتها من الأداء ومنها القوة المميزة بالسرعة، إما أهمية البحث فتكمن في السعي إلى تطوير هذه القدرة ومعرفة تأثيرها في الأداء المهاري لتكون عوناً للمدربين في العملية التدريبية. أما مشكلة البحث فيمكن أن توضع في تساؤل هو هل يتم استخدام تمرينات نوعية متنوعة لتطوير القوة المميزة بالسرعة على وفق العتبة اللاهوائية في الأعداد الخاص لمعرفة تأثيرها في تطوير الأداء المهاري. يهدف البحث إلى إعداد تمرينات على وفق العتبة اللاهوائية لتطوير القوة المميزة بالسرعة، ومن ثم معرفة تأثيرها في تطوير الأداء المهاري الدفاعي ( حركة اللاعب المدافع، والسحب الدفاعي). أما فرض البحث فيشير إلى أنّ هناك فروقاً ذات دلالة إحصائية بين الاختبارات القبلية والبعدية في متغيرات البحث. أجري البحث على لاعبي الشباب لنادي الأعظمية الرياضي بعدد (12) لاعب وبنسبة (16.66%)، إذ تم إجراء الاختبارات التالية (القوة المميزة بالسرعة للذراعين والرجلين، حركة اللاعب المدافع، السحب الدفاعي) وأستمر البحث للفترة من (24/8/2013 ولغاية 26/10/2013)، فضلاً عن الوسائل الإحصائية المناسبة. استنتج الباحثون إن التمرينات المستخدمة في البحث على وفق العتبة اللاهوائية أدت إلى تطوير القوة المميزة بالسرعة للذراعين والرجلين ومن ثم أحدثت تطوراً في متغيرات البحث المهارية. يوصي الباحثون بضرورة استخدام التمرينات البدنية اللاهوائية في التدريب كونها فعّالة في تطوير القوة المميزة بالسرعة والتي بدورها لها تأثيرها في تطوير مهارتي (حركة اللاعب المدافع، والسحب الدفاعي)، وذلك من خلال تخصيص الوقت الكافي لها في الوحدات التدريبية.
In this investigation a high density polyethylene (HDPE) was used as a substitute to polyvinylchloride in the production of lead acid battery separators. This has been achieved by preparing mixtures of different percentages of the feed materials which include a high density polyethylene (HDPE) locally produced, filler materials such as silica and oils such as dioctylphthalate (DOP) or paraffin which were added to the mixture to improve the final properties of the separator.
