Yes, over speed training is assisting the speed of the movement. This approach is more common with sprinters where they use a long band and a partner to tow the athlete and assist his sprint. There is pros and cons to this training style. The pros is it gives the central nervous system a feeling of moving at or above the bodies top speed. The cons is it could cause injury or it could degrade mechanics. I recommend using this approach in a training program but use it sparingly.

In use this approach in the level 2 program with the pitching mechanics. I use it to help the pitcher get a feel of what it is like to move at his top speed through the mechanics. The drills are called the 3X Assistance drills.
