Question
Successful anterior cruciate ligament injury prevention programs improve dynamic control of the knee by emphasizing proprioceptive training and strengthening of what muscle group?
1- Knee extensors
2- Knee flexors
3- Hip internal rotators
4- Hip flexors
5- Hip adductors

Answer (click for answer)
The correct answer is 2- knee flexors
ACL injury prophylaxis exercise programs are aimed at developing coordinated flexion – extension contractions in the knee. Therefore answers 3-5 are eliminated. A study looking at immature athletes of both genders found that female athletes fall behind in their hamstring strengthening. Put another way, their quadriceps become disproportionately stronger, and this imbalance puts them at risk for ligamentous injury. To balance the deficit, knee flexion strengthening (hamstrings) can improve the coordinated motion of the knee and potentially reduce the incidence of ACL injuries.
