Abstract

The aim of this study is to compare the repeatability of speeds and the fatigue index among football players according to their positions, in order to identify any statistically significant differences among them based on the requirements of modern football under the contemporary tactical approach (playing as a block). The authors of this study adopted a comparative descriptive methodology. The sample of the study consisted of U-21 players from the Union of Biskra team, which competes in the first national division, comprising 18 players, with 6 players representing each position (defense, midfield, attack). Data were collected through the Bangsbo test, and after the statistical processing of the study variables, the result showed no statistically significant differences in the repeatability of speeds and the fatigue index among football players according to their playing positions. In light of this, the researchers conducted a physical-tactical comparison based on the team's playing style (playing with a medium block) and built on the speed of transition for all players simultaneously. The authors concluded that there is a need to reconsider the physical indicators related to playing positions according to the tactical requirements and current updates in this field for proper planning of the training process. الملخص: الهدف من هذه الدراسة هو مقارنة قابلية تكرار السرعات ومؤشر التعب لدى لاعبي كرة القدم وفق مراكز اللاعبين للتعرف على إمكانية وجود فروق ذات دلالة احصائية فيما بينها حسب متطلبات كرة القدم الحديثة في ظل التوجه التكتيكي الحديث (اللعب بكتلة) حيث استخدم اصحاب الدراسة المنهج الوصفي باستعمال المقارنة. وتمثلت عينة الدراسة بلاعبي الفئة العمرية لأقل من 21 سنة لفريق اتحاد بسكرة ، وضمت 18 لاعباً، تم جمع البيانات من خلال الاختبار البدني (Test Bangspo)، وبعد المعالجة الإحصائية لمتغيرات الدراسة تبين أنه لاتوجد فروق ذات دلالة احصائية لتكرار السرعات ومؤشر التعب للاعبي كرة القدم باختلاف مراكز لعبهم. ، وخلص أصحاب الدراسة الى ضرورة اعادة النظر في المؤشرات البدنية المتعلقة بمناصب اللعب وفق ما تمليه الحاجة التكتيكية الى ذلك ووفقا للتحديثات القائمة في هذا المجال من اجل التخطيط السليم لبناء العملية التدريبية
