Cameras of that era were too crude to capture the split second when the rules of both Newton and Naismith were bent, so it was fortuitous that New York Times writer Arthur J. Daley was at the Y that day covering the tournament that would decide which Americans sailed to Berlin for the Olympic debut of the 45-year-old sport. This new “version of a lay-up shot,” Daley wrote, “left observers simply flabbergasted. Joe Fortenberry, 6-foot-8-inch center . . . left the floor, reached up and pitched the ball downward into the hoop, much like a cafeteria customer dunking a roll in coffee.”
Randomization was performed in computer-generated, permuted blocks of 6 to 10, stratified according to the participating ICU. Treatment assignments and a five-digit reference number were placed in sealed, opaque envelopes, which were opened by the person responsible for the preparation of the trial-drug solutions. The solutions of norepinephrine or dopamine were prepared in vials or syringes according to the preference of the local ICU. Each vial or syringe was then labeled with its randomly allocated number. The doctors and nurses administering the drugs, as well as the local investigators and research personnel who collected data, were unaware of the treatment assignments. The trial was approved by the ethics committee at each participating center. Written informed consent was obtained from all patients or next of kin.
During the 2009 NBA dunk contest, Howard had a separate goal brought onto the court, and the rim was noticeably significantly higher than a standard goal. Howard, after going into a 1950s-era telephone booth and again fashioning the Superman attire, caught a pass from Nelson and easily completed a two-handed dunk on the higher goal. While this was not performed for record-setting purposes, the dunk received a perfect score and a warm response from the crowd, in part because of its theatrics. Also in this contest, 5'9" guard Nate Robinson wore a green New York Knicks jersey and green sneakers to represent Kryptonite, playing on Howard's Superman theme. He used a green "Kryptonite" ball, and jumped over the 6'11" Howard prior to dunking. This dunk and the theatrics could have won the competition for Robinson, who was voted the winner by the NBA fans. Robinson then thanked Howard for graciously allowing him to dunk over him, asking the crowd to also give Howard a round of applause.

Seventy-nine years later, the feat that Daley unwittingly named “the dunk” still flabbergasts. But how it felt to Fortenberry, a pioneering barnstormer whose name we’ve forgotten despite the gold medal he and his teammates won in 1936, remains a mystery. “He never talked about being the first person to dunk and all that,” says 65-year-old Oliver Fortenberry, the only son of Big Joe, who died in ’93. Indeed, the famous dunkers throughout history have been either reticent on the subject or unable to adequately express how it felt to show Dr. Naismith that he’d nailed his peach baskets too low. After more than a year of rigorous research on the subject, I’ve concluded that the inadequacies of modern language—not the ineloquence of the dunk’s practitioners—are at fault. In the eight decades since Fortenberry rocked the rim, words have repeatedly fallen short in describing the only method of scoring, in any sport, that both ignores one of its game’s earliest tenets and, in its very execution, carries a defiant anger.

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.
The rate of death at 28 days in this study was close to 50%, which is to be expected in a study with very few exclusion criteria and is similar to the rate in previous observational studies.3,9,21-24 Our trial was a pragmatic study that included all patients who were treated for shock states, and therefore, it has high external validity. The study design allowed for maximal exposure to the study drug, since we included patients who had received open-label vasopressors for a maximum of 4 hours before randomization and since during the 28-day study period, the study drug was withdrawn last when patients were weaned from vasopressor therapies and was resumed first if resumption of vasopressor therapy was necessary.
The player approaches the basket and obstruction, and then leaps. During flight, some portion of the player's body is elevated above the obstruction. This may entail raising the legs or some portion thereof in-air to soar over the obstruction. In other instances, the trunk-moves over an obstruction as the legs pass around it. Common obstructions include: motor vehicles; crouched, seated or standing person(s); ball rack; or other available objects.
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).

For smaller guys much of the problem, and one I struggled with, is managing the ball. Like most guys my size I can palm a basketball if a grab it carefully, but realistically it isn’t going to happen without a little concentrated effort. Some of those big guys can make a basketball look like a volleyball, and they have no trouble getting hold of it and shoving it over the rim.
In the past, it has been possible for players to dunk a basketball and pull the rim down so hard that the glass backboard shatters, either around the rim itself or, at times, shattering the entire backboard, or the entire goal standard fails. Reinforced backboards and breakaway rims have minimized this at the college and professional levels, but it still happens at lower levels.
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.
In the 2000 NBA Slam Dunk Contest Carter used an elbow hang along with his reverse 360 windmill dunk and between-the-legs dunk. When performed, much of the audience was speechless, including the judges, because none had seen these types of dunks before (Carter's first round 360 windmill dunk is reminiscent of Kenny Walker's 360 windmill dunk in 1989 except that Carter spins clockwise, whereas Walker spins counter-clockwise).
Use a smaller ball. It's much easier, when you're first starting out, to try dunking with a smaller ball. You'll be able to palm it more easily and control your approach, making the maneuver more satisfying and your practice closer to the real thing. Continue dribbling and shooting exercises with the appropriate-sized ball so you're not getting too used to the "wrong" size, but keep a small ball around for your sick dunks.[1]
This is a dunk where the player takes off from a distance which is significantly further away from the basket than is considered typical. The free-throw line is most commonly constituted as the take-off point, an effect likely attributed to the easily observable span between the line and the basket in the view of the TV audience. In order to achieve the hang-time and altitude necessary, players will generally leap from one-foot to maximize the momentum generated from the half-court running start often required to complete the dunk. A cornerstone of dunk contests, dunks from a distance are also performed in games, most often on the fast break.

Many models have been constructed to identify the most important muscles in the vertical jump, with some conflicting results. Some have suggested that movement is governed by the gluteus maximus and quadriceps, while others have proposed that the hamstrings, quadriceps, and calf muscles are key. Importantly, no model has yet explored the role of the adductor magnus, which is the primary hip extensor in the barbell squat. This is relevant, as many studies have found that the squat is an ideal exercise for improving jump height, and maximum back squat strength is closely associated with vertical jump performance among athletes.
Increase your vertical leap. You will need the lifting power of your legs to get you in the air and up to the basket. Building a regimen of leg workouts that will increase the fast-twitch strength and the flexibility of your leg muscles can help you add inches to your vertical leap, getting you that much closer to the rim.[2] A good regimen to get started with might include:

Want to increase your vertical jump for volleyball fast? The easy way is to use our vertical jump bands and wear them while you practice your spikes! Just put on the vertical jump bands during volleyball practice and you'll be training your vertical jump while you are also practicing your volleyball skills. This means you don't have to do extra vertical jump workouts to gain inches on your jumping ability.

A study was carried out in 2015 to show the effectiveness of different shot types, including slam dunks. The study was carried out across five different levels of basketball (NBA, EuroBasket, the Slovenian 1st Division, and two minor leagues). Overall the study showed that slam dunks were a very effective way of scoring in the game of basketball, particularly in the NBA, which had the highest dunk percentage in the study.[37]
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.

I gave myself ten weeks to dunk again. It wasn’t going to be easy: I figured I’d need to add five or six inches to my vertical in order to dunk a regulation basketball. I was in half-decent shape, and at six-foot-three, I had height on my side. But I had a few things other than age working against me—namely feet that had flattened over the years to canoe paddles, and an ankle injury I’d never properly rehabbed.
After a one-week recovery period in January following Phase 1 of Jump Attack, Phase 2 brought an increase in intensity and time investment. This was the last stop before Phase 3, the wilderness where those attack depth jumps lived. (Attack depth jumps: Rest on your knees in front of a box; explode to your feet without using your hands; immediately jump onto the box; immediately jump as high as you can off the box, landing on the balls of your feet. Repeat. Many times. No blacking out allowed.) Phase 3 brought dramatic increases in both explosiveness and hip flexibility, two critical ingredients that I started to feel working in tandem. I emerged both confident and in dire need of another one-week recovery period, which I spent playing with our kids, watching dunk videos and mouthing the syllable Ow. Once healed, in early March, I returned to the rims with a friend whom I’d asked to toss lobs to me. There would be no more lifting. (After Jump Attack, what else could there possibly be?) From here on, I just jumped and recovered, jumped and recovered, attacking this tiny window of three or four weeks before my time away from the gym began to sap my strength. It would be over at that point, all over, whether I wanted it to be or not.
Which is why, on April 1, 2014, I dedicated myself to dunking a basketball for the first time. So that I could live it, breathe it, perhaps take a crack at it with my pen. I had tossed this idea around for years, realizing with each passing birthday that my chances of success were dimming. However, on that April Fool’s Day (a coincidence) I spent three hours on the court and at the gym, with a promise to myself to return several times each week until I threw one down like Gerald Green. Or at least like Litterial Green, who played in 148 NBA games between 1992 and ’99, and who, like me, was born in the early ’70s, stands 6'1", 185 pounds and is at no risk of having dunker carved into his epitaph.

We purchased this because of its safety evaluation and the high ratings. I did evaluate the negative reviews and was prepared for the issues reported, however; I found none of the comments in the negative reviews to be valid with our experience. First, for the people who complained about the assembly instructions- there are pictures....yes, the English is horrible, but there are pictures! Total assembly time, with one human, was 2 hours and 10 minutes. Assembly of the safety cage was the the most difficult part. Specifically, the foam comes in two sections, which makes it difficult to slide into the pocket. BUT, with a little patience it can be done. Second, to those who would rather purchase a unit from Walmart- this is a very fine product, with consumer quality pieces, they include gloves, spring tool, and a ladder- you don't get ... full review
By emphasizing certain muscles in your legs, you can train your body for the force needed to leap high. Increasing your vertical jump will improve your rebounding, blocking, dunking, and make you an all-around better basketball player. Here are a few of CoachUp’s favorite exercises for improving your leg strength and vertical jump. If you ever need extra motivation to get through these exercises on a daily basis, just re-watch these gifs and focus up!
Keep your upper body straight and your arms relaxed at your side. Extend your left leg straight out behind you with a slight knee bend. Place your right leg in front of you with your knee bent at a 90-degree angle and your thigh parallel to the floor. This is your basic lunge position. From this position, slightly lower your entire body, and jump to the opposite lunge position with your right leg extended behind you and your left leg in front of you. Repeat 25 jumping lunges in a row for three sets with a 1-minute break between sets.

Even so, the back squat does differ in important ways from the vertical jump. Primarily, it involves a much greater trunk extension turning force, because of the barbell weight on the upper back, and this likely contributes to the more hip-dominant nature of the squat over the vertical jump. Secondly, it is often performed to a deeper depth, which can alter the relative contribution of each of the hip extensors to the movement, because of their different leverages at each joint angle. And thirdly, it only involves accelerating up to midway through the movement, while the vertical jump involves accelerating right up until take-off. This also affects the relative contribution of the hip extensors, as force production will be required in the jump even when the hip is nearly fully extended, while this is unnecessary in the squat.

Independent 6'2" North American athlete Eric Bishop introduced a dunk entitled the 'Paint Job'. The title is in reference to the key on a basketball court, often known as 'paint' in common parlance.[36] Approaching along the baseline with a running dribble, Bishop jumped with one-foot at the border of the key, dunked with one-hand while gliding over the key and landed just beyond the border on the side opposite his take-off—a 16-foot flight.
Step 3. Land squarely on the floor on both feet (again, around hip-width apart) and immediately jump as high as you can, straight up in the air. It’s important that you spend as little time as possible with your feet on the floor before the jump—it should be a split-second reaction. Don’t lower down into a squat before leaving your feet. Just let your hips and knees dip naturally, then extend them explosively to launch upward. Drive your arms straight up as you do so.
The things I had going for me: an understanding spouse; a modicum of foot speed and leaping ability, flashed during the occasional Motrin-supported­ pickup game; proximity to one of the best training centers in the world; and, again, an understanding spouse. The forces working against me made for a longer list and included (but were far from limited to) my average hand size and arm length, a lower-back injury that I suffered while playing semipro football in 2009 and my age. I was 42.
Important Update! – I have been receiving a few emails/comments on players tracking their jump during the course of their program. Please understand that what you are doing when completing a jump program is breaking down the muscle.  You aren’t going to see improvements mid-week because the muscle hasn’t healed properly. That’s why I suggest only checking how much you’ve improved at the end of each rest week. Rest is just as important as the routine.
