Muscle strength imbalances around the knee are often observed in athletes after anterior cruciate ligament (ACL) surgery and hamstring muscle injury. This study examined three hamstrings-to-quadriceps (H:Q) strength ratio types (conventional, functional, and mixed) in thirteen female athletes with a history of hamstring injury, fourteen basketball players following ACL reconstruction and 34 controls. The conventional (concentric H:Q) peak torque ratio was evaluated at 120°·s -1 and 240°·s -1 . The functional (eccentric hamstring to concentric quadriceps) torque ratio was evaluated at 120°·s -1 . Finally, the mixed (eccentric hamstrings at 30°·s -1 to concentric quadriceps at 240°·s -1 ) torque ratio was calculated. Both ACL and the hamstring-injured groups showed a lower quadriceps and hamstrings strength compared with controls ( p &lt; 0.05). However, non-significant group differences in the H:Q ratio were found ( p &gt; 0.05). Isokinetic assessment of muscle strength may be useful for setting appropriate targets of training programs for athletes with a history of ACL surgery or hamstring strain. However, isokinetic evaluation of the H:Q ratio is not injury-specific and it does not vary between different methods of calculating the H:Q ratio.
