***We have all encountered or applied much of the advice given for
controlling TA during the early stages of a movement or during static
clinical situations, but how does one consciously activate TA during a
heavily loaded task like lifting, especially when the action is rapid or
explosive, as it is during Olympic weightlifting? In fact, is it important
or advisable to attemopt to do during complex and rapid motor tasks like
this?
Will the body not respond in the most individually suitable manner if the
person is taught to execute a lifting movement correctly without any emphasis
on trying to isolate certain muscles. After all, we are very familiar with
the general adage that "the body knows about movement, not muscles". Acquire
the optimal movement or motor skills for any human action and, in the
non-pathological, body, the rest should follow quite naturally in most people.
As someone who has been involved with Olympic weightlifting at all levels
for several decades, I have never come across a single lifter or coach who
has applied any of the clinically promoted muscle isolation methods of trunk
and "core" stabilisation, nor have studies ever shown that the incidence of
back injury is even vaguely elevated in this group of athletes relative to
the average population. Are these lifters just "lucky" or are all of these
theories about stabilisation more hypothetical than practical in really
demanding sporting situations?
