› Problem Statement: The aim of the study was to compare the angle-specific torque value and the peak torque values of isokinetic knee strength in both lower extremities in extension and flexion phases at different angular velocities between male and female soccer players and to determine whether there is a difference between the genders. › Methods: 26 female and male professional football players were included. The knee strengths of both lower extremities of the participants were evaluated using isokinetic dynamometry at 60°/sec and 180°/sec. The peak torque (PT) (Newton meters, Nm), body mass-normalized PT (Nm/kg), and H/Q ratios (%), angle-specific ratio (ASR) at 30° and bilateral strength deficit of the quadriceps and hamstring muscles were recorded for the dominant and non-dominant legs. › Results: There was no significant difference in H/Q ratio and ASR between the sexes. There was a moderate correlation between H/Q ratio and ASR. Female players presented significantly higher bilateral deficits for flexor muscles in both angular velocities (p<0.05). › Discussion: The results of the study can be summarized as follows: H/Q ratio depends on angular velocity in isokinetic strength testing; compared to men athletes, female athletes have a higher tendency towards asymmetry; and there is a positive correlation between the H/Q ratio and ASR values. › Conclusion: The H/Q ratio is different at various knee flexion angles and future studies should investigate if these approaches are better to identify risc factors.
