The end result of varations in power training is explosive power when the training program is designed to create explosive power. There are few applications that require only explosive power (the ability to generate high force over a very short time period). That is, while a moment of explosive power may be the goal of say the shot put, there is an acceleration phase, the moment that the shot is released, and a deceleration phase. Now I am seriously simplifying this here as the shot put is a very technical movement. Correct execution of the shot put is no less technical or less difficult than performing a double back flip in gymnastics. But each part of the performance requires preparation and training. Power training would be very useful in the development of explosive power, but there are many other aspects of using explosive power that are required to reduce the potential for injury.
To adequately discuss the topic here is not something that I would be comfortable doing. There is just too much potential for mis-interpretation.
