What is it, When does it occur, and Why is it important?
In a previous blog, we discussed Transformational Zones (TZs) where the loading motions are decelerated, and the energy absorbed is TRANSFORMED into energy for the exploding motions (desired movement). The blog discussed the reversal of movement direction, and the importance of a proper sequence. The sequence of bone and joint motion into the TZ is not the same as the sequence out of the TZ. The different sequence produces something that, at the Gray Institute, is called Proximal Acceleration Load (PAL).
PAL is an oxymoron. Loading occurs during deceleration. Exploding is a result of acceleration. PAL is the final, ultimate load on the muscle, tendons, and fascia. This occurs when the distal/peripheral joints are still moving into the load, while the proximal/central joints have already started to accelerate. The proximal acceleration creates the maximum tension in the soft tissues, making the explode more powerful. The reversal of bone motions must be in the proper sequence.
This PAL sequencing allows 110 pound female golfers to hit the ball 275 yards. PAL sequencing is the source of the axiom that great baseball pitchers throw with their legs. It allows tennis players to crush a forehand, even when their feet are not on the ground. It is a critical component of all efficient and powerful movements.
Practitioners of Applied Functional Science analyze and train in the TZs looking for the loss of proper sequencing, and to restore it to the movement. The distal segments might need to slow down. The proximal segments may need to speed up. The assessment must include all 3 planes of motion. The assessment movements must include authentic drivers of motion into and out of the TZ. The TZs selected should be both global, like those featured in the 3D Movement Analysis (3DMAPS), and task specific. The training utilizes tweaks of all the Observational Essentials in CAFS and the Performance System of 3DMAPS.
This momentary movement of proximal bones in a direction opposite the distal bones, is not only the “source of success”. Unfortunately, it also has the potential to cause injury somewhere. It may be overly simplistic, but too little PAL makes the movement ineffective and inefficient, but too much PAL can make the movement ineffective and creates additional strain that can be harmful to the tissues. This is the cause of many overuse injuries.
