Objective

Isokinetic evaluation allows accurate and reproducible measurement of dynamic muscle strength. It has several application areas, especially in sports, it allows the evaluation, rehabilitation and re-entrainment. It is rarely used for the hip joint.

The objective of this study was to report the isokinetic profile of the abductor and adductor muscles of the hip in Moroccan professional players, while comparing players with a history of groin for those without medical history at the hip.

Patients and methods

This is a prospective study in physical medicine and rehabilitation, including 36 professional footballers who have been performed concentric isokinetic evaluation mode abductor and adductor muscles of the hip at 60°/s and 120°/s. The distribution of variables was verified by the normality test of Shapiro, Wilk. The Wilcoxon test and U Mann-Whitney test were used to compare different isokinetic variables of the two groups evaluated.

Results

There was no statistically significant difference between dominant and non-dominant side in terms of the maximum peak torque, work, power, and adductor/abductor ratios. There was a significant difference between the players with a history of groin and those who showed no pathological history at the hip.

Discussion/Conclusion

A weak adductors compared to hip abductors may be involved in the development of the groin, especially an eccentric force deficit. The isokinetic allows the establishment of specific profiles and can be applied preventively early in the season to objectify and correct anomalies, particularly agonists/antagonists imbalances sometimes responsible for further damage. It allows a customized physical preparation, predicting the return to competition.
