| Background and aims: Muscle strength is one of the key factors in sports performance, and muscle strength imbalance is considered one of the risk factors in sports injuries. Athletic groin pain (AGP) is a frequent injury among the soccer player and could change the adductor/abductor muscles balance ratio due to the pain. This study aimed to investigate the comparison of hip adduction to abduction strength ratios in professional soccer players with athletic groin pain and healthy ones. Methods Thirty-two soccer players (control group (n=16) and AGP group in dominant limb (n=16)) who take part in the first and second division league participated in this study. The isokinetic dynamometer (BIODEX V4) at a 90 degrees per second speed was used to evaluate the peak of muscles torque in both dominant and none dominant limbs. The range of motion was considered between 20 degrees adduction up to 45 degrees abduction in concentric and eccentric contraction. In addition, the muscle ratios differences were compared with an independent sample t-test at a 0.05 significance level by SPSS software. Results The result showed that the adductor/abductor ratio in the dominant limb and concentric contraction was significantly higher in the control group than in the AGP group (p=0.01). There were no significant difference in other limb and contractions. Conclusion It seems that pain could change the adductor/abductor ratio in the concentric contraction of the participants' dominant limb. This finding could be used to compare athletes during screening and implemented rehabilitation process to normalize the player’s strength ratios to reduce injury rate. |
