The time of force application is basically a matter of nerve-impulse facilitation. In other words, movement speed is largely determined by how efficiently the motor- nerve impulses are transmitted from the central nervous system to the muscle fibers. The most effective way to decrease the time of force application in an event such as the shotput is to practice the event at full speed with a slightly lighter shot. Power can be increased by increasing the muscle force. St training has great influence on this factor.
Some coaches believe that fast weight training is more effective for developing power.
One can lift light weightloads quickly or heavy weightloads slowly, but one cannot lift heavy loads quickly. Muscle force can be best increased by using relatively heavy weightloads and slow training technique. Because more muscle force means more muscle power, slow weight training should be the preferred method for improving muscle power. As previously discussed under the power section, speed is essential in any power event. The faster one accelerates an object, the greater the initial stress on the involved tendons, ligaments, and muscle fascia.
