This statement is actually a false explanation. Research indicates that the quadriceps:hamstrings strength ratio is actually more imbalanced in females, with stronger quadriceps and weaker hamstrings, which can contribute to greater ACL injury risk. The other options all have some validity as potential explanations for the higher rate of non-contact ACL injuries in physically active women compared to men.
