دراسة مقارنة للنشاط الكهربائي (Emg)‎ لعضلات الذراع العاملة و المضادة بدلالة القوة العضلية و توقع الاصابات الرياضية لدى لاعبي الساحات المكشوفة و الصالات بكرة القدم

Abstract EN

The importance of this study in using (EMG) to find the places of weakness in the counter muscles, by comparison between the agonist and antagonist muscle and guide the specialist in sport to the best way to protect them from sport injuries.

The aims of the research: 1.

Using EMG apparatus to compare the main muscles and the antagonist muscles in the sport performance.2 To know the difference among the agonist muscles and the antagonist muscles in some changes of EMG apparatus in tests, which they are studied.

Third chapter: This chapter contains the procedure of the research.

The researcher used the descriptive curriculum with style of scanning and correlation venations.

The sample of this study had been selected which included (84) players in the football game.

Besides, tools which is used in the research, with doing experiment.

It also designs and limits the most important elements of research using questionnaire forms, which concerns enough statement for the special exercises of performance in power of muscular and how EMG device works.

Chapter four: This chapter included the presentation of analyzing and presentation of results and treating statistically then organizing in group of tables in order to discuss it.

In chapter 5, the researcher put the most important conclusions and recommendations and the most important conclusions.

There is a relationship between the correlation between the electrical signal variables and the strength characteristic of the speed of the muscles of the arm of the players of open squares2-There are significant differences for the players of the open squares in the strength test characteristic of speed.3- Results obtained on the differences between the muscles of football players (open fields and halls) against and antagonist muscles will help to emphasize the importance of the nature and quality of activity in reaching an appropriate degree of muscle balance.

Recommendations: 1.

Stress on the understanding of muscular balance or the proportion of the muscular power among the agonist muscles and the antagonist muscles among the movement of stretching and bending of joint and the limbs of the human body, to all the interested persons in the sport medical filed health of players, coaches, specialists in physical therapy and doctors.

In condition that this proportion is not less than 60% especially with the football players.
