Movement is quite simple and from that wonderful simplicity
comes the complexity of sports skill and performance. Twenty-five years ago in
an attempt to better explain movement and how we should effectively train
movement I came up with this simple diag
ram I call the Performance Paradigm. It
was somewhat like what Albert Szent-Gyorgi, once said, “Discovery consists
in seeing what everyone else has seen and thinking what no one else has
thought.” Essentially it is the stretch shortening cycle of muscle with a
more global interpretation and proprioception brought into consideration. It is
the basis for what some people call the Gambetta Method; to me it is common
sense. I use this to evaluate movement efficiency or deficiency and then to
guide training and if necessary rehab.
Essentially all movement is interplay between force
reduction and force production. The quality of the movement is dictated by our
proprioceptive system. We begin movement by loading the muscles – this is the
force reduction phase. Basically this is the eccentric loading phase as a well
as instantaneous isometric action that lends stiffness to the muscle. This is
the most important component of the performance paradigm, but probably the most
overlooked as well as the most misunderstood. There are several reasons for
this; the most notable being that it is less measurable. Because it is more
difficult to quantify we have tended to emphasize the more measurable
component, force production. It is during the force reduction phase that most
injuries occur. Think landing on one leg and tearing an ACL or planting to cut
and spraining an ankle. It is
during this phase that gravity has its greatest impact; it is literally trying
to slam the body into the ground.
Once force has been reduced the subsequent result is force
production. Force production is easy to see and easy to measure. Consequently
it gets an inordinate amount of attention in the training process. We see it
because it is the outcome. It is how high or far we jump. It is how much we
lift. But just because it is easy to see and measure does not mean it should receive
the inordinate emphasis, in training that it does. It must be stressed that it
is the component of the performance paradigm that is highly dependent on the
other phases.
The third component of the Performance Paradigm is
proprioception. Ultimately it is the glue that binds a whole functional program
together is proprioception. Proprioception is the awareness of joint position
and force derived from the sense receptors in the joints, ligaments, muscles,
and tendons. It is that component that gives quality to the movement. “The quality of movement, in part, is dependent
upon neurologic information fed back from proprioceptors within muscles and
joints to the higher brain centers. The information returning to the central
nervous system from the periphery includes “data” concerning tension of muscle
fibers, joint angles, and position of the body being moved.” Logan and
McKinney (Page 62) It is the feedback mechanism that positions the limbs to be
able to achieve optimum efficiency. It is a component of movement that has been
all but ignored in most traditional training programs until recently. It is
highly trainable, especially if it is incorporated as part of a whole program.
It is almost too simple. Perhaps to appreciate
proprioception we should look at the extreme case of a stroke victim that is
able to return to normal movement patterns. Why can’t an athlete who has all
their capacities enhance the quality of their movement by focusing on the same
things that the stroke victim has to focus on to get back to function? The key
to that is proprioception. We must strive to constantly change proprioceptive
demand throughout the training program in order to enhance the quality of
movement.
The performance paradigm will serve as a guide to determine
how we train all components. It can also serve as a very useful guide to help
us to evaluate movement from a slightly different context. It should serve as a
guide to be more functional in our approach by emphasizing the timing and
sequence of all three components of the paradigm. The synergistic interplay
between them will produce the highest quality of movement.
It is very easy to get caught in the trap of measurable
strength. How much you can lift or how many foot-pounds of force you can
express on a dynamometer are meaningless numbers. Functional training does not
depend on measurable strength. Quality of movement, coordination and rhythm are
more important. The goal is always to apply the strength that is developed in
the actual sport performance. How is the force expressed? Can you produce and
reduce the force? Force production is all about acceleration, but often the key
to movement efficiency and staying injury free is the ability to decelerate and
stabilize in order to position the body to perform efficiently. A good
functional training program will work on the interplay between force production,
force reduction and stabilization. The end result is functional strength
