I will state this again - there are no irrefutable, quantitative studies that prove that static stretching prevents injury. All the ones that I have found used limited, controlled groups that are usually surveyed as to how they "feel". If someone can show me a real study where there is hard proof stretching helps, I'll listen.
On the other hand, here is some food for thought:
A researcher at the University of Minnesota conducted a review of all available scientific literature on the association between stretching and running injuries. This researcher found that “Overall, the evidence suggests that increasing range of motion beyond function through stretching is not beneficial and can actually cause injury and decrease performance. These findings should be used to challenge common warm up practices in athletics.” (BTW, this is what I have been doing, reviewing everything I can find).

Another recent study seems to back up these claims that stretching beyond functional range of motion can cause injuries. DY Park and L Chou looked at recent studies on Achilles tendon injuries, a very common problem for distance runners. Park and Chou said “Recent prospective studies have contended that reductions in plantar flexor strength and increases in ankle dorsiflexion range of motion from stretching the Achilles tendon may increase the risk of injury.”

BTW stormholloday, I am not questioning the credentials of anyone here who has trained as a physiologist or rehab specialist. I am questioning some of what you were taught. I have found that too many medical professionals like to wield their credentials as a stick to beat down anyone that questions their statements or pronunciations. I have a brother who is an orthopedic surgeon and I constantly have to take him to task on this behavior.
JM, who better to understand the relationship between injuries and their rehab and prevention? Someone who has had to recover from them and who has put in the time reading the research or someone offering speculative, unproven advice such as yourself? Instead of shooting the messenger, maybe its time to broaden your knowledge base.
Rickson and Systemic, thanks for your insight.
