Hi, In this video we’re gonna look at how to
properly inflate a basketball. In order to develop proper dribbling,
passing, and shooting skills, it’s important that you work with a
basketball that’s properly inflated. Some basketballs come with stamp near the
inflation hole that looks like this. They may look official
but the instructions are misleading There’s no official inflation pressure
for a basketball. If there were, then basketball’s would behave
differently when you play on a hard
surface like concrete than they do when you play on a soft
surface like a wood court. Even wood courts have different amounts
of hardness depending on their construction. The right thing to do is refer
to the rules book on this topic. Here’s the wording you’ll find
in the NFHS rules book. Rule 1, Section 12, Article 2. The ball shall be
inflated to an air pressure such that when it is drop to the playing
surface from a height of 6 feet, measured to the bottom of the ball, it shall rebound to a height, measured to the top of the ball, of not less than 49 inches, when it strikes on its
least resilient spot, nor more than 54 inches, when it strikes on its most resilient spot. Ignoring all the talk about resilient spots, this means you hold the ball
so that its bottom sits at 6 feet, or 72 inches, and let it drop. It should bounce so that it’s top comes to a point somewhere between 49
inches and 54 inches. If there’s a place
where you often practice you can make it easier to keep your ball
inflated properly by putting some marks or tape in a convenient place
where the flooring is similar to where you will be playing. Use a tape measure to place a mark
or some tape at 72 inches. Then put two more marks or tape
at 49 inches and 54 inches. Now hold the ball so that
its bottom is even with the 72 inch mark. If your arm is long enough put your head in a position
between 49 and 54 inch marks. If your arm isn’t long enough
you’ll need to drop your head to that position as the ball falls. Now simply drop the ball as
straight down as you can. Watch the top of the ball, If it bounces up somewhere
between the two lower marks the ball is ready. If it bounces to a spot
higher than 54 inches it has too much ai and you’ll need to let some air out. If it bounces lower than 49 inches then you’ll need to add some air. Once you’ve done this several times see if you can repeat the process
without using the marks. Just imagine them in your mind. Check yourself every so often against actual
marks to be sure that your imagination hasn’t shifted up or down. You should always have a
small portable air pump with you in your gym bag. This one cost me about
twelve dollars. Be sure to lubricate the needle before
inserting it into the ball. Water’s a good choice but most of us
just put some spit on it. Every ball loses air over time. Depending on the quality and age of your ball you may have to put additional air
in it every time you use it or several weeks may pass
before you need to add air. If you accidentally put too much air the easiest way to let some air out is to unscrew the needle from the pump and insert it in the ball. After some air has escaped from the ball measure the bounce height again. And that’s it. You’re set to go. Just remember the numbers
72, 49, and 54.
