There are many kinds of dunks. Let's assume Kobe Bryant a simple dunk - one made by standing directly under the basket and jumping vertically for the stuff. Since Kobe's hand touches the basket after he jumps, we have to compute for the distance between the ring and his vertically stretched arm.
10 feet (height of NBA basket) + 6 inches (extra height necessary to stuff the ball) - 6 feet (kobe's shoulder height) - 2 feet 6 inches (kobe's vertical arm length) =2 feet.
Kobe Bryant jumps approximately 24 inches to make a dunk. Add a few inches for the more spectacular dunks where he has to jump a little higher.
you can dunk anything as long as you jump and hold it like a basketball
it's when you jump straight up and dunk a basketball
you jump up and throw the ball in
Yes Yao Ming has to jump to dunk. Only four inches though, his height is listed as 7'5" or 7'6" and his standing reach is listed as 9'8". Therefore he needs only four inches to reach the regulation height 10' basketball rim.
Just jump and dunk; there is no other way to explain it. If you want to know how to increase your ability to dunk, buy a pair of stretch bands. They will increase your vertical jump in a few weeks of use.
this how you do run up to the net jump shune
