Linda,
Very interesting, and very much against everything we have known about
stretching before exercise. Is the paper published on the internet, and if
not, where can I get hold of this paper. However, I have a few questions:
Is there any further research that will backup this claim the pre-exercises
stretching is not beneficial for injury prevention?? Was the study specific
in saying which muscles they stretched, how they stretched them, whether
they stretched for a certain time frame, and whether they stretched after
their exercises?? it seems to me that 1538 people is a large sample, and
would be difficult to control these factors, which are as important in
injury prevention as simply doing stretches.
