Hang Time - Can It Be Improved?

As he is coming down the court and jumps, scientific laws begin to apply. These laws state that every action has an equal and opposite reaction. What this means in layman's terms is that the player pushes against the floor and the floor exerts a force back. This action/reaction makes the player to leave the floor. When a player pushes harder on the floor, the floor pushes back harder causing the player to be propelled higher.

If a player is running during the jumping process, his/her center of mass follows a parabolic route, which essentially looks akin to a rounded off mountain top. A persons "center of mass" is situated close to their midsection. This means that, if the person were to continue in exactly the same position for the duration of the entire jumping action, his/her midsection (and consequently, full body) would follow this route. However as a player jumps while running, the center of mass is lifted - and manipulated.

By raising his knees, he's raising his center of mass relative to his head. He does that on his way up. As he comes back down then, he puts his legs back down. This makes his center of gravity lower. This in effect raises his head in relation to the center of mass. The head does not follow the parabolic path. The head stays at one height.

So what you get is for a fraction of the time in the air, the head stays at the identical height, but ,during the whole time the center of mass goes up and down.

In essence, the player's head is the key to why we believe in hang time.

While we look at each other, we don't frequently look at the person's "center of mass". We frequently concentrate on a person's head (or at least the upper part of the whole body) . What happens at that second is a bit of an "illusion", but it actually is happening. The person's center of mass is changing and this causes his head to stay in the same position for a longer time.

Well, if "hang time" is not genuine, how is it that one person can remain in the air longer than another person? The REAL answer is because that person JUMPS HIGHER. If you can't increase your hang time then, you have to learn to jump higher!
