In today's softball and baseball world "bat speed" is the most common phrase you will hear at the ball field. "It's bat speed that hits home runs." I am a firm believer of that. That bat speed does have a lot to do with how far the ball is launched. But, I think that your bat speed has to follow a fluid swing with good mechanics. Anyone that has a good swing and has good bat speed already, is only going to hit the ball farther if they can increase that bat speed.
Important Note: You want to increase your bat speed using the same weighted bat that you usually use. If you go to a lighter bat to increase your bat speed and it works that is great, but 9 times out of 10 you want to increase your speed with your bat weight that you have been using. I am a firm believer in moving a bigger and heavier bat at the incoming softball will only increase the distance.
Simultaneous Summation Of Levers
Simultaneous Summation Of Levers is the same principle as the Domino effect. When you are swinging a softball bat, your swing actually starts at your feet, then your ankle, your knees, your hips and so forth. Your swing starts from the bottom and goes upwards as the body turns into the pitch. You will actually be exploding into the ball with all your force, that you built up into your mighty swing..
It should lead into one explosion at the end.
