THE SECRET OF THE SWEET SPOT
Have you heard of the sweet spot?
The term is widely used among athletes, and it comes from sports like baseball, tennis, and golf.
Baseball players know that hitting the ball exactly on the sweet spot feels the best and leads to a more powerful hit.
Now you may be wondering how to find the sweet spot.
Follow the steps below, which show you how to test it for yourself.
What do you need?
You only need a bat, a hammer, and a friend.
You can do the test by yourself, although it’s easier and more fun to do it with a friend.
How do you find it?
First, you hold the bat loosely between your thumb and pointer finger so that it is hanging down toward the ground.
Then, have a friend tap the bat gently with a hammer, starting at the fat end and moving toward the handle.
You should feel vibrations in your fingers whenever the bat is struck.
However, when the sweet spot is hit, you’ll feel nothing.
You may also notice a slightly different sound when this spot is struck.
What’s going on?
When you hit a ball and feel no vibrations, it means you’ve hit it on the sweet spot of the bat.
1.
Whenever a bat is struck, it vibrates in response.
These vibrations travel in waves along the bat.
2.
At one spot, the waves cancel out, and little of the bat’s energy is lost to vibrations.
3.
The less energy the bat loses, the more energy the ball gets.
As a result, the ball flies farther.
SUJIN: If I hit the ball exactly on that spot, I don't feel any shaking in my hands.
When I hit the middle of the bat with a hammer, I didn’t feel any vibrations.
However, I did feel vibrations when I hit other spots of the bat.
It was pretty interesting.
ANDREW: When my hammer hit the sweet spot, I did not feel any vibrations.
I felt like I was going to hit a home run.
TINA: In the last baseball game, I hit an over-the-fence home run!
I think I’ve finally found the SWEET spot!
Do you have a baseball and a bat around you?
Why don’t you try to find the sweet spot when you swing the bat?
Keep trying until you are able to strike the spot whenever you want to.
Sooner or later you will enjoy hitting balls farther and maybe even seeing them fly far enough for home runs.
What’s your next step?
You can find sweet spots not only on a bat but also on a tennis racket and a golf club.
Wouldn’t it be fun to find all of them and become an all-around great player?
