I'm still seeking true root cause of the quad dom. issue. To me, these are the areas most likely to be the cause:
1. Genetic
Has a very strong genetic link in my house, me and the oldest share a lot of characteristics and happen to both be quad dom., my youngest is much like her mom, and both are glutes dom. This would also help support why so often kids of athletes are generally very athletic as well. If it is genetic, I am sure that there is an underlying reason (like #3 below).
2. Limited range of motion
I lead away from this for a couple reasons. The first being that my DD is about the bendiest kid I seen... The second reason is that DD has been specifically checked out by three physical therapists and the only thing one of them observed was low ROM in her ankles (almost a grand later, no improvement, but her ankles are really mobile now, ). I want to note, that among the PT experts I've discussed this issue with, almost all of them are resigned to this camp as the root cause. I've just collected too much empirical evidence to the contrary to even entertain it further. We've invested too many years doing exactly what the experts prescribed to give it another shot. It would take a heck of a sales pitch to try it again.
3. Too high dexterity
This might very well be the culprit and could also have linkage to genetics. Again DD is bendy and has a high Beighton score for hyper-mobility. Of the kids I've observed with this problem, most tend to be somewhat "bendy" in nature, but I could probably study this more precisely. If this is a significant characteristic, the next goal would be to try and figure out what specifically is the cause.
Back to MB's post, I do think that some knee injuries are related to kids with a similar issue. My daughter has a lot of knee valgus, and I do feel that there could be some level of correlation between knee valgus and quad dominance. Not sure I'm resigned to study the topic in this depth though. Maybe after the kids are done with softball.
FWIW Chong has done an excellent job of correlating low/common ankle sprains to quad dominant athletes. Low ankle sprains are very common in armature athletics, but we don't see them all that much in college/pro athletics. He has a couple great videos further supporting this claim.
