I remember seeing something on TV in the last year could have been catalyst? on research that had been done on the theory that women are more prone to injure themselves due to the effect that the menstruation cycle has on the structural intergrity of tendons, ligaments and muscles. I think the stuff they found out disproved the theory that the ligaments got weaker or looser but they actually got less flexible and the muscles themselves became more easily fatigued and hence more prone to injuries - the study was on the knee injuries in netball players. Does anyone else have a better recollection of this ?
Regards

Adam Bryant (a biomechanist now at Melbourne Uni) was behind that research (on ACL injuries) -- its all to do with 'stiffness' of the lower limb at different stages of the menstrual cycle (its different for oral contraceptive users and non-users).
I am involved in a project with Adam and others on changes to foot and lower limb funtion (including stiffness) during the menstrual cycle and it implications for running shoe designs...Last edited by a moderator: Oct 20, 2005 -
Thanks Craig is there an article? Also did the US study mention the significance of the cycle in injuries?
Also any early findings from the research on foot stiffness ? Is there much research in the way of pregnancy and post delivery issues with the feet ? -
Mark - no data on foot stiffness yet - that project is not quite ready to start yet. As luck has it, I am just down from Adam's office today and got this off him:

This is timely:

Mark - i missed this in an earlier post:
The effect of pregnancy on footprint parameters. A prospective investigation
I know there have been a few since then, just no have them handy. -
I have a vague memory of Simon Bartold in Oz speaking on the early stages of some research into this.
All I have. -
Simon is also involved in the project I mentioned above on foot and lower limb function at different stages of the menstrual cycle. He presented a paper on it at the recent confernce in Christchurch. He has spoken at a number of conferences on some of the issues surrounding the female runner.

Press Release:
FEMALE SPORTS STARS ENCOURAGED TO TAKE THE PILL
WEDNESDAY, FEBRUARY 15, 2012 AT 2:40PM

For the elite athlete who has not had a period in years, or in the case of athletes who didn't even go through puberty as a result of their excessive training (Olga Korbut being a prime example) how does this help? :rolleyes:
And what about the post-menopausal athlete?
What about the testosterone taking female athlete? -
Amenorrhea itself is indicative of major issues—nevermind the ACL injury risk due to relatively minor modulation in the stiffness of ligaments, tendons, or muscles. If you've got a female athlete who is not menstruating due to her training, in the running world at least, that's problem #1. Most reputable coaches at the NCAA level will not allow female runners to train/compete if they've been without a menstrual cycle for several months, as there's a well-established link between that and bone density issues. A torn ACL is in some ways a preferable injury when compared to a femoral neck stress fracture.
Some wisdom from the coaching world:

As for testosterone—how often do you see a female athlete openly taking testosterone? We have a word for that in the running world... -
Amenorrhea is common among female athletes http://www.ncbi.nlm.nih.gov/pubmed/19642982 and self reporting is inaccurate and underestimates the problem: http://www.ncbi.nlm.nih.gov/pubmed/19945961 etc. While the elites may be watched over carefully, the keen amateurs are usually not. I see far more keen amateurs within my practice than I do elites.
How often do you see any athlete openly admitting to taking anything performance enhancing, John? They usually only admit it when they've been caught. Does this mean that it doesn't happen?
Here's a thought: I wonder if Caster Semenya has a regular menstrual cycle? -

"Female high school athletes have higher injury rates and risks of injury than their male counterparts"
"Our research has shown that when women train at an elite level, they become more prone to injury. We believe this is because they over-train and under-eat. This causes their oestrogen levels to fluctuate more than usual,’ Mr Bartold said."
Is there research that compares the injury rate/risk of elite male and elite female athletes?
Is there research that compares the sport specific injury rate/risk of female college and elite athletes?
