Abstract

Purpose:
Changing strength ratio of internal to external rotator muscles is a common condition in overhead athletes with shoulder impingement syndrome. The purpose of this study was to investigate the effect of traditional and TRX (total-body resistance exercise) suspension training on the strength ratios of internal and external shoulder muscles.
Methods:
Thirty-three athletes with shoulder impingement syndrome in Kerman city were selected and grouped into two groups of training (traditional and TRX Suspension training) and control group. To assess the strength, the subject sitted at the edge of the table with arm position located near the body and elbows at 90 degrees of flexion. The subject was applied the maximum pressure to hand-held dynamometer for 5 seconds, each person performed three attempts and an average performance of the person was based on statistical work.
Results:
The results showed that after the training period, improvement in the strength ratio in shoulder rotator muscles were observed (p=0.004). The results showed that there was a significant difference between the traditional and TRX group with the control group (p<0.001, p=0.009 respectively), but there was no significant difference between the traditional and TRX training groups (p=0.58). Furthermore, the average score changes in the TRX group was higher.
Conclusion:
Since traditional exercises require several training tools, however, TRX exercises only one tool is needed, as well as the TRX exercises execute in the closed-kinetic chain, it can be concluded that TRX exercises can be used as a substitute for traditional exercises in places with restricted exercise space.
