Intensive Training Effects on Shoulder Muscle Injury in Table Tennis Players

Abstract

Introduction: The glenohumeral joint has the greatest range of motion. Its stability is relatively poor. It depends on muscle strengthening and increased proprioception in the articular and adjacent joint tissues. Muscle-strengthening training for this joint is still an empirical subject related to table tennis players. Objective: Explore muscle strengthening training's effect on shoulder muscle injury in table tennis players. Methods: Eight table tennis players from a university were selected as a research subject, separated, and classified between injured and control group. Three weeks of strengthening training were adopted to rehabilitate the rotator cuff injury of the table tennis team athletes. The joint angle test and kinematics were collected with isokinetic force measurement employing Cybex-6000. The EMG and other relevant data were collected before and after the experiment. Results: The infraspinatus strength test results of 8 athletes before the experiment were 1.88 ± 2.10 versus 1.61 ± 1.80 after the experiment; there was no change in pain among 5 of the eight athletes, the shoulder pain of 1 athlete increased, and the shoulder pain of the other 2 table tennis players decreased. Conclusion: Strengthening exercise by intensive shoulder training proved effective in conjunction with traditional rehabilitation, positively influencing hypertrophy and proprioception of the joint complex.
