Good luck Emilie - sound like an interesting and well considered study - we
won't know until we try! and that's what research (clinical or otherwise) is
all about.
Cheers,
Anna.

Dear Mel
I agree - other causes of muscle failure will all have to considered and
ruled in/out before differences in core muscle recruitment patterns can be
blamed for peripheral injury. That's not really the focus of my research.
I'm really hoping to be able to establish whether specifically training
T ab will result in a change in hamstring strength/power profile at all. If
an enhanced hams performance is discovered then I'm going to have to go
about explaining it based on our current knowldge of muscle performance
during functional activity patterns.There are a large number of correlation
studies looking at criterion related validity that establish correlation
between muscle performance on isokinetic testing and athletic performance in
the non injured athlete. The difficulty that I see, speaking as a clinician
who sees these guys all the time, is trying to link athletic performance
with strength profile in the chronic hamstring strainer. Maybe as you say
strength (in either T Ab or hams) may have nothing to do with it, but maybe
we're just looking at the wrong parameters when looking at torque curves.
I'm looking forward to finding out!
Thanks for the references!
Anyone out there know of text or articles, research or theory, about anybody
using TAb technqiques to treat hams strains?
