“Loading” is when the pitcher holds his weight back over his back leg, while his front side continues building momentum towards the target. This is why strong legs and core, produce powerful pitching. Look at Eric Gagne in this picture. He is squatting on his back leg, waiting for the perfect time to fire his hips and then his shoulders.

A component of velocity is produced when torque is generated in the two rotational pivots. The rotation of the hips, to the rotation of the shoulders. Tim Lincecum calls this the “Rubber Band.” Think of your core as the “Rubber Band.” Rotating the shoulder and hip pivot separate from each other would tighten the “Rubber Band.” This sounds a lot easier than it actually is to perform. This is why a small amount of athletes can throw a baseball over 90 mph.

The importance of the “Load” is that it holds the weight back until the first pivot, the hips, are ready to build maximum torque. Triple extension in the back leg drives the momentum into front foot strike, forcing the hips to pivot. Then “Separation,” or “Scap Loading” must occur to build torque in the core. There is that word again “Loading”. Notice the pitcher here in this position. His hip rotation is now complete. It has built maximum torque. You can see this in the tightening of his “Rubber Band.” Notice his shirt is stretching like a rubber band would. Now, all that is left to do, is to fire the last pivot, the shoulders forward and then stabilize. Stabilization allows the momentum generated from the body to transfer to the ball.

If the pitcher didn’t “Load” his weight back, as his front side continued to build momentum and set the first pivot of the hips, then top velocity could never be achieved. It would also put more stress on the rotator cuff, because the torque would build more in the shoulders than the core.

The “Load” is also just as important for hitters to develop power. Notice this picture of A-Rod in the “Load” position. The difference is hitters are more compact because they have to defend the strike zone. Therefore, a hitter cannot have a long stride like a pitcher. This brings up another good point. A good stride is considered to be the length of your body height. The “Load” position also increases your stride. So when you here a Coach yell out that you need to stride out more, then you will understand that this means you are not “Loading.” The importance of the “Stride” is that it moves you closer to the plate, shortening the distance the ball must travel, which increases velocity and a good “Stride” gives you more time to build momentum.

In conclusion, a good “Load” position is more valuable for a pitcher than a high lift leg. It generates as much or more momentum but is critical in generating optimal hip to shoulder separation. Here is a gallery of more pitchers in the “Load” position. View gallery here.
