Dunking isn’t much different. You’ll likely find yourself getting slightly higher with each attempt at first, but before long, fatigue will set in and your vertical leap will decrease. At this point, it’s a good idea to end the session, rather than try to push through and force yourself to jump higher. It’s an indication that your nervous system has mustered all the energy it has to help you jump, and you need to let it rest. Give your legs a couple days’ off, then come back again and try.
This calculator tells you how much you need to jump to dunk a basketball. It will also give you an estimated force required to jump that high. The more you bent your knees the less force you'll need but you will need a lot of energy to take you from that position to the top. You can increase your vertical by training your legs to be able to deliver that much force.
```I think it’s the sort of thing that a lot of kids probably fantasize about, me included. Just like you might want to become an astronaut or something like that. I was always one of the tallest kids in my class, but I never really tried to dunk. And so as an adult, you start wondering a little bit about what sorts of things you left on the table, that you never really tried your hand at. And I got it into my head that I’d pick up this childhood fantasy of mine and see if I could dunk.

Results: You need a 0 Inch vertical leap to touch the rim and 6 Inch leap to dunk considering that you have to jump about 6 inches over the rim to dunk. To accomplish that you have to leave the ground at a speed of 1.73 m/s vertically no matter how much you weigh. You need a force of 0 Newtons against the ground based on your weight to reach that speed assuming you bent your knees at an angle of 60 degrees. The force depends on how much you bent your knees.

After four months of failing to pull off anything even resembling a real dunk, the planets aligned on Aug. 9: After at least 19 failed attempts that afternoon, I dunked a soccer ball on a middle school court whose rim measured 9' 11". (The original basketball, incidentally, was a soccer ball, property of Dr. Naismith’s employer, Springfield College.) Video from that afternoon shows me standing there, looking confused, in the moment afterward. Did that just happen? Failing had become so routine that even this small success felt foreign.
Like Todd and me, Nicholson was a two-foot jumper, and he echoed what Todd had told me was another flaw in my technique: “Your next-to-last step has to be a lot bigger. That big leap forward with your right foot—your penultimate step—that’s what allows you to explode off the ground.” To demonstrate, Nicholson sent me a video of Carter’s performance at the 2000 NBA Dunk Contest, which was a bit like showing a Monet to a finger painting kindergartner and saying, “No, like this.”
Whichever equipment you use, the first thing you’ll need to do is measure your reach standing flat-footed on the floor with one arm fully extended straight overhead. (You can measure your reach up against a wall for the chalk option.) Then, when you mark the highest point you touched, you’ll subtract your reach from that number. For example, if your reach is 90 inches and you touched 115 inches up on the wall with your chalk, your vertical leap is 25 inches.
Because of the possible combinations of starting and finishing hands, and raised-legs, there are many variations on the basic under-the-legs dunk—more so than any other.[17] For example, in a 1997 French Dunk contest, Dali Taamallah leapt with his right leg while controlling the ball with his left hand, and once airborne he transferred the ball from his left hand, underneath his right leg to his right hand before completing the dunk.[18] NBA star Jason Richardson has also pioneered several notable variations of the between-the-legs including a lob-pass to himself[19] and a pass off of the backboard to himself.[20] Independent athlete Shane 'Slam' Wise introduced a cuffed-cradle of the ball prior to initiating the under the leg transfer and finishing with two-hands.[21] While a number of players have finished the dunk using one- or two-hands with their backs to the rim, perhaps the most renowned variant of the dunk is the combination with a 360°, or simply stated: a 360-between-the-legs. Due to the athleticism and hang-time required, the dunk is a crowd favorite and is heralded by players as the preeminent of all dunks.[citation needed]
Start with a ping-pong ball, then a tennis ball, then a softball, then a volleyball, then a youth-sized basketball, and on up until you can dunk with a regulation size ball. If you can't palm the ball, then you will need to learn how to control the ball with two hands until the last minute extension for the dunk with one hand, or you will have to jump high enough to dunk two-handed.
##### Before you take on these vertical jump exercises, spend a few minutes looking over the plyometric section of our website. When you increase your vertical jump, you’re actually altering the nature of your muscle fibers, and our plyometric articles can explain how this works. Meanwhile, keep working on strength-building exercises for your quads, glutes and hips, and remember to keep an eye on any hesitation between your jumps.

After warming up, I proceeded to slam Jeff’s best lobs off the back rim at least 10 times, watching these missed dunks rebound high over the lane and land somewhere near the three-point line. It’s tough to express how difficult it was to pack up and walk away from the court on such days, to listen to my body when it told me it had reached the point of diminishing returns. To come up with yet another way to tell the wife: No, not today, Sugar. But I came reeeally close.
The record for the most WNBA dunks belongs to Brittney Griner. As a high school senior, she dunked 52 times in 32 games and set a single-game record of seven dunks.[47] As a standout at Baylor University, Griner became the seventh player to dunk during a women's college basketball game[48] and the second woman to dunk twice in a single college game.[49] In her WNBA debut on May 27, 2013, Griner dunked twice, and as of 2014, has five WNBA dunks, including the first in a playoff game (August 25, 2014).

Darryl Dawkins of the Philadelphia 76ers was notorious for two glass-shattering dunks in 1979 resulting in the league threatening to fine him and eventually installing breakaway rims.[42] Twice in his rookie season (1992–93) during games, center Shaquille O'Neal dunked so hard that he broke the hydraulic support of one goal standard (against the Phoenix Suns) and broke the welds holding up another goal standard, causing the basket to break off and fall to the floor (against the New Jersey Nets), although in neither case did the glass break. This resulted in reinforced backboard supports as well. During that same season, New Jersey's Chris Morris shattered a backboard in a game against the Chicago Bulls (the most recent shattered-backboard incident in the NBA to date). The NBA has made shattering the backboard a technical foul, although it will not count towards a player's count of seven that can draw a suspension, or two towards ejection from a game, and it counts towards a player's count of six personal fouls. This has assisted in deterring this action, as it can cost the team points.
I'm 5"11 and 12 years old, and i'm able to touch the rim, but it's very inconsistent. like 50% of the time I can wrap my 3 biggest fingers around it, or i dont touch it the other 50% of the time. I've been training for about 4 months, doing calf raises every day until they cramp, and everyday i try to touch the rim at my gym or school or at any court. I found out i could touch the rim 2 days ago, but is there any way to add 7 inches to my vertical instead of doing thousands of calf raises again, because i really want to be able to dunk by 8th gradr

```Circulatory shock is a life-threatening condition that is associated with high mortality.1,2 The administration of fluids, which is the first-line therapeutic strategy, is often insufficient to stabilize the patient's condition, and adrenergic agents are frequently required to correct hypotension. Among these agents, dopamine and norepinephrine are used most frequently.3 Both of these agents influence alpha-adrenergic and beta-adrenergic receptors, but to different degrees. Alpha-adrenergic effects increase vascular tone but may decrease cardiac output and regional blood flow, especially in cutaneous, splanchnic, and renal beds. Beta-adrenergic effects help to maintain blood flow through inotropic and chronotropic effects and to increase splanchnic perfusion. This beta-adrenergic stimulation can have unwanted consequences as well, including increased cellular metabolism and immunosuppressive effects. Dopamine also stimulates dopaminergic receptors, resulting in a proportionately greater increase in splanchnic and renal perfusion, and it may facilitate resolution of lung edema.4 However, dopaminergic stimulation can have harmful immunologic effects by altering hypothalamo–pituitary function, resulting in a marked decrease in prolactin and growth hormone levels. 5

The force-velocity profile can be described by three elements: (1) maximum strength, (2) maximum velocity, and (3) the slope of the force-velocity gradient, because this is what determines whether the balance between force and velocity is optimal at the desired speed for force production. Each of these factors is an independent predictor of vertical jump height.

Technique Tip: Determining how far out in front of you to place your front foot may require some trial and error. At the bottom of the motion, your front knee should be somewhere above your heel to mid foot. If your knee is behind your heel, your foot is too far forward; if it’s out over your toes, step out further. One trick to find the right distance is to start in the bottom position and adjust your stance from there. Then stand up and have someone hand you the dumbbells.
Robert Cole, de The Times dijo: "Klein se burla del "complejo de desastres del capitalismo" y las ganancias y las privatizaciones que van con él, pero no proporciona una crítica convincente -que argumente sobre los principios del mercado libre-, y sin ésta, La doctrina del shock desciende en una maraña de historias que a menudo son preocupantes, a veces interesantes y, en ocasiones, extrañas".17​

An alley-oop dunk, as it is colloquially known, is performed when a pass is caught in the air and then dunked. The application of an alley-oop to a slam dunk occurs in both games and contests. In games, when only fractions of a second remain on the game or shot clock, an alley-oop may be attempted on in-bound pass because neither clock resumes counting down until an in-bounds player touches the ball. The images to the right depict an interval spanning 1/5 of a second.
A strut is a major structural part of a suspension. It takes the place of the upper control arm and upper ball joint used in conventional suspensions. Because of its design, a strut is lighter and takes up less space than the shock absorbers in conventional suspension systems. Struts perform two main jobs. First, struts perform a damping function like shock absorbers. Internally, a strut is similar to a shock absorber. A piston is attached to the end of the piston rod and works against hydraulic fluid to control spring and suspension movement. Just like shock absorbers, the valving generates resistance to forces created by the up and down motion of the suspension. Also like shock absorbers, a strut is velocity sensitive, meaning that it is valved so that the amount of resistance can increase or decrease depending on how fast the suspension moves.
Don't do jumping exercises 7 days a week. Four or five days per week is enough. If you do it every day, you may give up after a week or two. The idea is to keep exercising for months, or years, consistently. Note that we have not organized an actual jumping program. Inside Hoops is providing exercises that should help your fitness and leaping ability.

Three weeks after I received that counsel, on a rare afternoon when I felt fully rested, I dunked a volleyball on a 9' 11" rim. Again, I knew I could never swing my arms while palming a basketball the way I’d swung them while palming that volleyball, but I’d be lying if I said it didn’t feel badass. Thirteen failed attempts later, I did it again. Then two more times, each one an unexpected thunderclap. All of the explosive Olympic lifting I’d been doing was paying off, but my problem wasn’t going anywhere: How could I get my hand and a basketball over the cylinder? A lob to myself off the backboard? A big bounce off the blacktop?
Where it (relatively) falters is in the oft gratuitous sexual content, occasionally drawn out beyond all reason. This holds particularly true of Million's trawl through the mind's red light district full of tempting whores like Orientals Kia and Tricia Yen and Caressa Savage, abusing herself at length with a scary looking dildo. At best, the sex is still positively riveting though with sweet Shayla subjugated to a pair of fearsome gargoyles (T.T. Boy and Vince Voyeur in amazing body make-up) and a group of pony girls - remember them ? - at film's climax.
For women's basketball, to dunk or not to dunk has long been the question. It’s the ‘wow factor’ that WNBA haters often point to as proof that the women's game doesn't deserve the fandom, fame and fortune that the guys get. Cristen and Caroline talk to two dunking superstars of past and present to sort through the courtside gender politics and controversy of stuffing the net and find out whether more women bringing the slams could settle the score.
Shock absorbers are basically oil pumps. A piston is attached to the end of the piston rod and works against hydraulic fluid in the pressure tube. As the suspension travels up and down, the hydraulic fluid is forced through tiny holes, called orifices, inside the piston. However, these orifices let only a small amount of fluid through the piston. This slows down the piston, which in turn slows down spring and suspension movement.
A forceful, dramatic move, as in That indictment was a slam dunk if ever there was one. This expression is also often put as a verb, slam-dunk, meaning "make a forceful move against someone," as in This is a great chance for us to slam-dunk the opposition. The idiom comes from basketball, where it refers to a dramatic shot in which the ball is thrust into the basket from above the rim. It was transferred to other activities from about 1980 on.
Then, in terms of exercises, you really need to get your whole body stronger. You need to improve your core, and obviously you need to improve your legs. So someone who is interested in jumping higher will find themselves doing a lot of squats. And I would suggest that if someone just started this, they could do a lot of squat exercises without even going to the gym or even bearing weight. You know, get up in their office cubicle and do ten squats. Three sets of ten reps of squats is a good workout.
