Study On The Effect Of Muscle Strengthening Exercise On Table Tennis Players' Shoulder Damage Muscles Group

In table tennis,all racked swing complete should need shoulder joint auxiliary other joints,The characteristics of this project determine that the shoulder joint is the most frequently used,it is easy to damage in table tennis,especially rotator cuff injury.The burden of the local motion of shoulder repetitive swing pull action caused by the heavy,the damage caused by small muscle group is one of the important causes of rotator cuff injury.To strengthen the prevention and treatment of shoulder joint injury,to reduce the influence of shoulder joint on the technical action of athletes,it is an urgent problem to be solved in daily training.Eight table tennis athletes of Jilin University are research objects in this study,and the athletes with shoulder muscle injury were selected by shoulder muscle injury screening method.Then,combined with the anatomical structure of the rotator cuff and the characteristics of this sport,reinforcement training(the dumbbell side pulling in lateral position movement;the lateral dumbbell stretching movement;etc.)lasts for three weeks was carried out to the table tennis athletes for their rotator cuff injury rehabilitation.Through the comparison of training before and after the manual examination,assessment of shoulder injury and data of shoulder's active internal and external rotation characteristics,impact on recovery of table tennis athletes with shoulder muscle injury with the strengthening of shoulder muscle are learned,and an effective rehabilitation therapy of table tennis athletes with shoulder injuries are provided.Through the research,we get the following conclusions:1.From the training before and after the subaxillary muscle strength test,empty cans test,lift off test and other test results of the test results can be seen,targeted reinforcement exercises for table tennis athletes subscapularis muscle injury,supraspinatus muscle tendinitis Of the rehabilitation have a certain effect,but little effect on the degree of shoulder pain is not.2.The results of PRI showed that there was no significant difference in the scores of PRI among the athletes after the treatment and reinforcement training.The total score and the emotion had obvious improvement compared with before the training,After the reinforcement training,the athletes on the whole,especially the emotional changes have been obvious,the training of athletes will be a great help.3.From the characteristics of internal rotation and external rotation of the shoulder joint,the range of motion of the shoulder joint is reduced,the strength of the internal and external rotation is decreased,and external rotation were also significantly increased,indicating that targeted manipulation and reinforcement exercises can improve internal rotation of the shoulder joint,Rotation of the range,to enhance the internal rotation,external rotation of the muscle strength,which help to improve the speed and effect of hitting,improve the technical action effect.In summary,targeted therapy and shoulder reinforcement exercises can improve the athlete's mood,enhance shoulder stability and mobility,enhance shoulder internal and external rotation of the muscle strength,and produce adaptive technology changes.
