McGill advocates for quadratus lumborum training
via the isometric side bridge exercise. He has presented evidence that the
isometric side bridge trains MF, TVA and QL in one exercise. He also
maintains that the medial fibers of the QL function as stabilizers and the
lateral fibers function as prime movers. His painstaking research is
compelling (he's done many studies involving intradiscal pressure with
different lumbar exercises as well as EMG studies with different
exercises).
Mel,
Please let us know how the visit goes.
I'd be very interested in learning about his views, thoughts, research,
etc...any insight you would pass along would be much
appreciated.

Subject: Pilates Core Training
Myths?
< I was referring to past discussions (which ended up with
people getting
into heated debates) about TVA in which you were, in effect,
refuting the
role of the TVA, its dysfunction and isolated training.
I was ribbing you in
a good natured way because of your use of the TVA in
order to kick Pilates
around some more. In other words, you were
arguing both sides of the coin
and I was kidding you about it.

*** I know! Anyway, I don't bother to pay any special
attention to my TvA,
since my neural computer seems to have served me well
for many decades of
participation in life and very strenuous Olympic
weightlifting and martial
arts. Whether or not my TvA or any other
individual muscle has been playing
some sort of superordinate role I do not
really know, but whatever my
computer has done it seems to have recruited
some quite appropriate muscles
to make my daily and sporting life a real
pleasure, despite the apparent
risks of training most days with very heavy
loading.
I often argue several sides to any given debate - that helps
to clear out
many of the cobwebs of bias and belief. Moreover, it
iterates the admonition
expressed by the ending of a book that I always
suggested that my students
read, namely"Illusions" (Adventures of a
Reluctant Messiah) by Richard Bach -
the ending said "Everything in this
book may be wrong".
Anyway, this weekend our home in Denver will be
filled with some interesting
times discussing TvA and core stability,
because one of the world's great
researchers in this field, Dr Stuart
McGill and some of his PhD students from
Canada are spending a few working
days with us. His detailed new book, "Low
Back Disorders" (Human
Kinetics) specially aimed at therapists will be of
great interest to
members of this list. What I have read of it so far
has
convinced me that it is a very useful and informative addition to my
library.
