Abstract :The aim of this study was to compare bilateral and ipsilateral lower extremity strength asymmetry in male and female soccer players. This study was conducted with cross-sectional research model. A total of 74 soccer players, 36 women and 38 men, who play active soccer in Mersin, participated in the study voluntarily. The body composition of the participants was measured by bioelectrical impedance analysis and isokinetic strength was measured by Cybex II Norm isokinetic dynamometer. Isokinetic strength test was performed for both knees at 60 o/s for 3 sets 5 repetitions. Bilateral and ipsilateral force asymmetry were calculated with formulas based on peak torque force. Since bilateral force asymmetry values were not normally distributed, Mann Whitney U test was performed, and since ipsilateral force asymmetry values were normally distributed, independent sample t test was performed. When the bilateral strength asymmetry of male and female soccer players were compared, it was observed that there was a significant difference in both quadriceps (p 0.05). When the ipsilateral force asymmetry values were examined, it was observed that male soccer players (56.04%-55.21%) had more ideal values than females (54.49%-53.88%). As a result, in our study findings, it was observed that the strength asymmetry values of the athletes were at an ideal level and there was a difference between the genders in bilateral asymmetry, but there was no difference in ipsilateral asymmetry.
