Training for improved vertical jump.
Explosive strength is a characteristic of performance that is common in many sporting endeavors.
Research has shown that it does increase explosive power in individuals who begin training with average strength. In some cases it might even reduce the ability of the muscles to develop force rapidly. Heavy strength training is of little benefit to already strong individuals who wish to perform explosive movements. It is the type of training that is important. A change in muscle structure, such as that which can be developed through heavy weight training, should be accomplished prior to the commencement of specific explosive power training.
