Jonathan mentioned plyometrics and I found this thread....

Jonathan-I agree. plyometrics are great for power cause they increase speed, which is a huge component. Many people seem to think its for strength gain but I disagree. Its for speed. The more sport specific the better.

Remember you are dealing with elastic strain energy and stretch reflex so no counter jumps etc..swinging arms back then forward while on ground is just to slow to do what you are trying to do. To much hight or too much of a drop means too much energy is transfered into the ground, wheather from time (shorter the better) or from heal slap etc..

Same with weight. A little resistance and doing a move fast teaches the body to go faster...
