I think there is a physiology element to it - I know from personal experience that I have a lot of problems with my left knee, with a key underlying reason is being a woman and the alignment between hips & knees in comparison with men; wider hips coming into the knee, versus men that are more straight through that area. I never actually looked at it from a hormonal/menstrual point of view, but if(when) I have further issues in the future, that's something I may start recording or taking note of
The harder grounds may be an element or a contributing factor but I don't think it's as simple as saying it's one or the other - if it was just a case of harder grounds being the reason, why don't we see more ACL's by soccer players? Soccer seasons in both Australia & America are played for the duration of their respective summers and I just don't recall hearing about the spate of ACL's from those leagues. And even from a "football" perspective, the Northern Territory Football League finals start this weekend - be interesting to see what their spate of ACL injuries are because surely the grounds in the NT aren't somehow softer than the grounds that AFLW is played on
I think there's validity to seeing what contribution hormones may play - I thought it was very easy to dismiss until looking more into it and seeing the various big name clubs & organisations around the world for whom it is a genuine consideration. I think we are constantly learning more about the ways our bodies work, so why not explore if this is a contributing factor
It sound's like we're in the same boat.
No doubt there is hormonal factor.
There have also been a number of studies including one commissioned by the AFL back in 2001 that concluded that the climate/surface factor increases the likelihood of ACLS. There are also studies of soccer teams that play in the same league- the teams in the hotter climates have more acls.
The problem with some of these studies is that there are some confounding factors like type of grass etc. But there is definitely a trend that the hotter the climate/the drier the grass, the more acls.
That the AFL is choosing to publicise the hormone research instead of the surface/climate factor tells you all you need to know about the AFL.
