Can A Player Really “Hang” In The Air?

Friday, November 20th, 2009

We have all heard of “Hang Time”, but is it factual? To get directly to the point, scientific laws manage this, there is no such entity as “hang time”. Some people will maintain that this can’t be – exclaiming how they have seen one player or another hang in the air longer than another. But, in reality, any basketball player (including “Air Jordan” himself) just makes it appear as if they are floating in the air.

Read below for details on what really happens when any player jumps.

As he is coming down the court and jumps, scientific laws start to pertain. These laws say that each action has an equivalent and opposed 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. If the player exerts a greater amount of force on the floor, the floor exerts a larger amount of force back. This causes the player to go higher in the air.

If a player is running in the course of the jumping process, his/her center of mass follows a parabolic path, which in essence looks akin to a rounded off mountain peak. A persons “center of mass” is located close to their midsection. This means that, if the person were to stay in precisely the same position for the duration of the entire jumping act, his/her midsection (and consequently, full body) would go along this path. Typically though, a player does not stay in the same position. He will bend and twist.

One thing that players regularly do is raise one (or both knees) while he is jumping.. He does that on his way up. On the way down, of course, he lowers his legs back down and that, in turn causes the center of mass to come back down. 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.

If you can envisage it then, the head follows a smooth course up and down though the person’s center of mass does not.

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

When one person looks at another, they tend to not look at the middle of their body. Instead, we typically look at the other person’s head. What happens at that instant is a bit of an “illusion”, but it actually is happening. The head stays in the same place for an unusually long time because the person changes his center of mass.

Well, if “hang time” is not real, how is it that one person can stay in the air longer than another person? The only choice left is that he can JUMP HIGHER! If you can’t increase your hang time then, you have to learn how to jump higher! How can you do this?

Is There Such a Thing as Hang Time?

Sunday, June 14th, 2009

Is there such a thing as “Hang Time“? To get straight to the point – it is a matter of science – “hang time” is not “real”. Most people will not believe this, using their favorite player as an example and exclaiming how he can hang in the air longer than anyone else. But, in reality, any basketball player (including “Air Jordan” himself) just makes it seem as if they are floating in the air.

Here’s the details of what is happening when a basketball player goes up for a slam dunk (but any other sport where jumping is involved applies as well).

As he comes down the court, a player jumps and Newton’s third law of physics takes over. This law states that every action has an equal and opposite reaction. What this means then is that the player’s foot pushes against the floor and the floor pushes back against the foot. This action/reaction causes the player to leave the floor. The greater the force the player exerts when pushing against the floor, the more force the floor exerts back – resulting in the player going higher into the air.

If a player is in motion (running) during the jump, his/her center of mass follows a parabolic path, which basically looks like a rounded off mountain top. A persons “center of mass” is located around the middle of their body. This means that, if the person were to stay in exactly the same position during the jump, his/her midsection (and therefore, entire body) would follow this path. But as a player that is running jumps, the center of mass is lifted — and manipulated.

By bringing his knees up, he raises his center of mass relative to his head. He does that on his way up. On the way down, of course, he lowers his legs and that brings the center of mass back down. This effectively raises his head in comparison to the center of mass. The head does not follows the parabolic path. The head stays at one height.

So what happens is during part of the time in the air, the head stays at the same height, but ,during the entire time the center of mass follows this parabola.

In essence, the player’s head is the key to why our eyes believe in hang time.

When we look at another person, we don’t usually concentrate on the person’s “center of mass”. We usually look at the head (or at least the upper part of the whole body) . What happens then is somewhat of an “illusion”, but it really is happening; the head is staying constant for an longer than normal time because he/she changes his center of mass.

Well, if there is no such thing as “hang time”, how is it that one person can stay 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! How can you do this? Check out these Vertical Jump Program Reviews for more information.
