Doesnt state height under the forefoot, so we really dont know the all important "Heel Pitch", 9cm heel could have a 8cm forefoot platform for all we know reading the text ;)
If it read 9cm Heel pitch it would allow us to know, as heel pitch refers to the difference between fore foot and heel height's
I won't be buying into any of the results from a doctoral candidate at the University of Vienna's Centre of Sport Sciences and University Sports, in Austria quite yet, thank you very much:D.
Slow news week at CNN:confused:
Of the other two cited studies - 11 subjects - 14 subjects?
Hmmmmm.
In Walking on High Heels Changes Muscle Activity and the Dynamics of Human Walking Significantly I like this quote "The results indicate a large increase in bone-on-bone forces in the knee joint directly caused by the increased knee joint extensor moment during highheeled walking, which may explain the observed higher incidence of osteoarthritis in the knee joint in women as compared to men."
Which is very believeable. However I would have thought that normal increased ligamentous laxity during the last trimester of pregnancy, the extra weight associated with full-term pregnancy, and the increased Q-angle associated with the wider female pelvis may also have a bearing on the higher incidence of knee O/A in females.
Perhaps the authors mention this in the full text - but probably not.
I'm having trouble with the term "bone on bone forces" at the knee..... I could see saying "increased joint reaction forces" that could potentially lead to degenerative change in the menisci and hyaline cartilage...perhaps i'm bieng picky..but it is a doctoral candidate...
