أثر الاعاقة القسرية بوساطة الاحزمة المطاطية و ردود الافعال الحركية لتحسين الأستجابة الحركية و النشاط الكهربائي لمهارة الدفاع عن الملعب من الطيران و الغطس بالكرة الطائرة

الملخص EN

The aim of the study was to identify the effect of forced disability by means of rubber belts and motor reflexes to improve the motor response and electrical activity of the skill of defending the stadium from flying and diving in volleyball.

The problem, its nature and the objectives set for the research determine the type of study design used, so the researcher used experimental design in the style of two equivalents groups.

As for the sample, they are the players of the Degara Club for the youth volleyball team for the 2018-2019 sports season and the number (18) players.

(4) players were excluded for the Center Center because of their little participation in the performance of the skill of defending the stadium in the matches, as they constituted 2.98% of the research community, and therefore the number of individuals in the sample was (14) players, representing 6.71% of the research community.

They were divided into two experimental and control groups.

With 7 players for each group, the research tools used an electromicuric device, which stands for "EMG" to study the electrical muscle, and this device has the ability to detect, record and store the signal (EMG), which is a biological signal that represents the electrical currents generated within the muscle during its contraction.

, As well as test the skill of defending the stadium N Aviation, the results were testing the defense of the stadium to fly and diving gave a clear picture of the actual during the games performance, the response motor is affected positively to exercise coercive disability commensurate with the performance of the skill to defend the stadium to fly and dive, the more efficient femoral and brachial muscles using exercises forced disability rubber belts - electrical activity.
