Abstract
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 by scientific way according to studied riles and by that we can get the safety and full ability in physical practices during the sport activity. The objectives 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 exercises which they are studied. 3- To know the percentage of the antagonist muscles action in the changes of the EMG apparatus through some suggested exercises. The Methodology: the researcher used the descriptive curriculum with style of scanning and Correlations . the sample of this study had been selected which included (30) players in the foot ball 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 , besides included the most important things of statistical means . THE CONCLUSIONS : 1- Existence of different and a accepted percentages for the antagonist muscles in comparison with the agonist muscles in sport performance . 2-. The result of differences among the agonist muscles of football players and the antagonist muscles will help to assure the importance of nature and quality of the activity in reaching to the suitable muscular balance. THE MOST IMPORTANT RECOMMENDATION WERE : 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. 2- Interest in measurement of proportions of muscular balance amp among the agonist muscles and the antagonist muscles with the athletes in general, in regulated periods in condition that this proportion is not less than 60% especially with the football players .
