دراسة تحليلية مقارنة لسرعة الاستجابة الحركية بين جدار الصد و التغطية في مراكز اللعب(2-3-4)‎ للاعبي الكرة الطائرة الناشئين

الملخص EN

The aim of the research is to identify the speed of the kinetic response of the players, the research sample between the two skills of the blocking wall and the covering of the blocking wall of the players.

The research sample and comparison between them in the front line centers, and the research problem was derived from the weakness in the kinematic speed of some junior players in the skills in question.

Research on a sample consisting of 12 players from the specialized school players in Abi Al-Khasib within Basra Governorate, aged 14-16 years, using the descriptive method.

And covering the blocking wall, and then collecting the results and treating them statistically to identify the results, the most important of which is the presence of significant differences between the players of the research sample in the speed of the kinetic response between the blocking wall in the two centers 2-3-4 and between the speed of the kinetic response of the players of the research sample in the coverage of the blocking wall of the centers 2-3 -4.

The researchers recommended the need to pay attention to the variable speed of the kinematic response because of its distinctive performance role and mastering the skill of the blocking wall, as well as covering the blocking wall, in addition to paying attention to that category in the skill of the blocking wall and covering the wall because of its role in the team's victory, as well as recommending the use of a measuring device The speed of the innovative kinematic response to measure the variables of the rest of the skills in volleyball, and science to develop it to measure the rest of the skills in other activities away from volleyball
