Some players thinking jumping off two feet to be more comfortable, but it’s different for every player. Take time while you’re practice your jump to find what’s the most comfortable for you. As you’re learning the right way to jump, comfort is crucial because you don’t want to hurt yourself making a move that feels awkward. You want to be comfortable taking off and landing - and that can be done a number of different ways.

Vertical jumps are used to both train and test for power output in athletes. Plyometrics are particularly effective in training for power output, and include vertical jumps of different types in their protocol. In one recent study, training with plyometrics (which included continuous vertical jumps) was shown to improve jump height and boost vertical jump performance to similar degrees in combination with very different resistance training protocols, indicating that the plyometric jumping contributed to the increased jump height more than resistance training. Research into plyometric jumps found vertical jumps to be among the highest in terms of muscle recruitment (as measured by electromyography), power output, and ground reaction force produced.[8][9][10] Fatigue has been researched in athletes for its effect on vertical jump performance, and found to decrease it in basketball players, tennis players, cyclists, rugby players, and healthy adults of both genders.[11][12][13]
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.
In 2004, as a high school senior, Candace Parker was invited to participate in the McDonald's All-American Game and accompanying festivities where she competed in and won the slam dunk contest.[51] In subsequent years other women have entered the contest; though Kelley Cain, Krystal Thomas, and Maya Moore were denied entry into the same contest in 2007.[52] Brittney Griner intended to participate in the 2009 McDonald's Dunk Contest but was unable to attend the event due to the attendance policy of her high school.[53] Breanna Stewart, at 6'3" (191 cm), Alexis Prince (6'2"; 188 cm), and Brittney Sykes (5'9"; 175 cm) competed in the 2012 contest; Prince and Sykes failed to complete their dunks, while Stewart landed two in the first round but missed her second two attempts in the final round.[54][55]
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

Perhaps the most popular obstruction-modified dunk is the Dubble-Up. Aptly eponymous of the its pioneer—T-Dub, an American dunker hailing from Minnesota—the Dubble-Up starts with a person standing before the basket, holding the ball above their head. The dunker approaches and leaps as though their groin would soar above just above the head and their legs around the stationary person. Just prior to clearing the person, the dunker will assume control of the ball with one or both hands, guide it under a raised leg, transferring it to the appropriate hand, clearing the ball-holder, raising the ball above the horizontal plane of the rim, and finally guiding it downward through the basket. While the Dubble-Up mimics a between-the-legs dunk, Kenny Dobbs and Justin Darlington have both performed an under-both-legs variant.
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.
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.”
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.
The hips and glutes are the primary muscles that help us jump higher and increase our vertical. To increase power in these muscle groups, attach the Kbands securely around your legs and plant your feet wider than shoulder width apart. Sit deep in a squat position (knees in line with toes, hips pushed back) and hold the move for a full 30 seconds. To see the effects of this move in your vertical jump, you should feel a burn in your rear, hips and quads.
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.
When I was growing up, basketball was big in my neighborhood. Everyone wanted to be able to dunk on a regulation 10-foot high basket and, thus, everyone focused on improving their vertical jump. The progression usually went a little something like this: touch the rim, grab the rim, hang on the rim, dunk with a volleyball and, finally, dunk with a basketball!
No, I think there’s a practical aspect to that. It’s hard to grip a basketball. I mean, that’s another physical challenge. I have pretty small hands, and one thing I had to train myself to do, which I couldn’t do at the start of this project, is palm a basketball. So that involved fingertip push-ups, to get the tips of your fingers much stronger. It involves, while hanging out and watching television, trying to palm a basketball for as long as you can. You want to get into a quick, full sprint, and you want to be able to grip the basketball as you go up to jam it. So doing those things can be a challenge. That’s partly what’s behind people doing the alley-oop-type things or throwing it up off the backboard. In some cases, they simply can’t grip the ball on the way to the hoop, so their solution is to throw it in the air, catch it, and try to bring it down.
About 100 yards away from this 9' 10" breakaway rim (which came to sound, each time I grabbed and released it, like someone closing the metal baby gate at the top of our stairs) was a brown, oxidized, immobile 9' 1" version, a hand-ruining iron maiden where, in front of the occasional puzzled onlooker, I practiced (and practiced) the timing and the hand and wrist work required to dunk. I knew early on that my regulation dunk, if it ever came to pass, would have to come from a lob of some sort—a bounce to myself, either off the blacktop or underhanded off the backboard—after which I would hypothetically control the ball with one hand just long enough to flush it. Mastering the placement and the delicate timing of such lobs would prove to be a quixotic pursuit in and of itself. But it was necessary, not just because of my hand size (7 ¾ inches) but also because I needed to keep my arms free so I could swing them at takeoff, adding much-needed lift to my leap.
In basketball, the ability to jump high can be pretty important, especially for layups and dunks. Thus, it’s no surprise that many people who play basketball, either professionally or just for fun, want to be able to jump higher to improve their game. Luckily, by performing certain exercises, losing weight, and perfecting your technique, you can significantly improve your vertical leap and jump higher in basketball.
A vertical jump is defined as the highest point an athlete can touch from a standing point jump, less the height the athlete can touch from a standing position (standing reach height). The best place to start with your vertical jump improvement is testing your vertical jump. This will serve as your reference point to see how you’re increasing your vertical.
I scoured the Internet looking for guidance. There are dozens of sites promising a path to dunking, most of them coded at the dawn of the Web. It was daunting finding one that seemed legit. I ended up paying $67 for the Jump Manual, an online program offered by Jacob Heller, a trainer with a 42-inch vertical who counts NBA players among his clients, according to his website. Next, I ordered a pair of Strength Shoes. You’ll remember these if you’re a basketball player of a certain age—the ridiculous-looking training kicks popular in the ’90s, with a platform under the toe that places your bodyweight on the balls of your feet.

If the patient was already being treated with a vasopressor at baseline, that agent was replaced as soon as possible with the trial-drug solution. If the patient was already receiving dopamine and this agent could not be discontinued after introduction of the trial-drug solution, the dopamine was replaced with an open-label norepinephrine infusion. Open-label dopamine was not allowed at any time. Epinephrine and vasopressin were used only as rescue therapy. Inotropic agents could be used, if needed, to increase cardiac output.
The dose was determined according to the patient's body weight. Doses of dopamine could be increased or decreased by 2 μg per kilogram per minute and doses of norepinephrine by 0.02 μg per kilogram per minute (or more in emergency cases) (see Figure 1 and Figure 2 in the Supplementary Appendix, available with the full text of this article at NEJM.org). An example of the dose-escalation table is provided in Table 1 in the Supplementary Appendix. The target blood pressure was determined by the doctor in charge for each individual patient. If the patient was still hypotensive after the maximum dose of either agent had been administered (20 μg per kilogram per minute for dopamine or 0.19 μg per kilogram per minute for norepinephrine — doses that have been shown to have similar effects on mean arterial blood pressure12,13), open-label norepinephrine was added. The dose of 20 μg per kilogram per minute for dopamine was selected as the maximal dose because this upper limit was the standard of care in the participating ICUs, in line with expert recommendations14 and international guidelines.15
Other obstruction-dunks are worth noting: Haneef Munir performed a Dubble-Up, dunking with his right-hand and then caught and dunked a second ball with his left hand—a yet to be duplicated dunk pioneered by Jordan Kilganon on a lower, non-regulation rim. Jordan Kilganon, a Canadian athlete, approached from the baseline a person standing, holding the ball above their head. Kilganon leaped, controlled the ball in front of his torso and raised it above the horizontal plane of the rim before bringing the ball downward into the hoop and hooking both elbows on and hanging from the rim.

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.
Some days I would be doing leg exercises — you want to give yourself a 48-hour break between heavy lifting involving any given part of your body, to give yourself time to recover. Some days, I’d go out to the track and do a track workout like sprints. I was avoiding doing long-distance running, because I didn’t want to develop slow-twitch muscles. I wanted to concentrate on fast-twitch muscles. And then for fun, on the weekends, I would play soccer or pickup basketball. I was becoming a better athlete because of this. Not only was I faster and stronger, but I was also more confident, in terms of just the run of play in any of these team sports, because I was more athletic than I had been.
When tendons elongate to a greater extent during a jumping movement that is preceded by a countermovement, the muscle lengthens less. This produces two effects. Firstly, the greater elongation of the tendon means that more elastic energy is stored during the countermovement, which is then released in the subsequent jumping phase. Secondly, the smaller elongation of the muscle means that countermovement depth can be greater for the same shortening velocity in the subsequent jumping phase, because the muscle never lengthened that much to begin with. Since shortening velocity determines force, this allows the same muscle force to be produced, despite the larger joint range of motion.
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.

The player approaches the basket and leaps as they would for a generic dunk. Instead of simply dunking the ball with one or two hands, the player allows their forearm(s) to pass through the basket, hooking their elbow pit on the rim before hanging for a short period of time. Although the dunk was introduced by Vince Carter in the 2000 NBA Slam Dunk contest, Kobe Bryant was filmed performing the dunk two years earlier at an exhibition in the Philippines.[22] Colloquially, the dunk has a variety of names including 'honey dip', 'cookie jar', and 'elbow hook'.
Data on hemodynamic variables and doses of vasoactive agents are shown in Figure 3 and Figure 4 in the Supplementary Appendix. The mean arterial pressure was similar in the two treatment groups at baseline, and it changed similarly over time, although it was slightly higher from 12 to 24 hours in the norepinephrine group. The doses of the study drug were similar in the two groups at all times. More patients in the dopamine group than in the norepinephrine group required open-label norepinephrine therapy at some point (26% vs. 20%, P<0.001), but the doses of open-label norepinephrine that were administered were similar in the two groups. The use of open-label epinephrine at any time was similar in the two groups (administered in 3.5% of patients in the dopamine group and in 2.3% of those in the norepinephrine group, P=0.10), as was the use of vasopressin (0.2% in both groups, P=0.67). Dobutamine was used more frequently in patients treated with norepinephrine, but 12 hours after randomization, the doses of dobutamine were significantly higher in patients treated with dopamine. The mean (±SD) time to the achievement of a mean arterial pressure of 65 mm Hg was similar in the two groups (6.3±5.6 hours in the dopamine group and 6.0±4.9 hours in the norepinephrine group, P=0.35). There were no major between-group differences in the total amounts of fluid given, although patients in the dopamine group received more fluids on day 1 than did patients in the norepinephrine group. Urine output was significantly higher during the first 24 hours after randomization among patients in the dopamine group than among those in the norepinephrine group, but this difference eventually disappeared, so that the fluid balance was quite similar between the two groups.
The amount of resistance a shock absorber develops depends on the speed of the suspension and the number and size of the orifices in the piston. All modern shock absorbers are velocity sensitive hydraulic damping devices - meaning the faster the suspension moves, the more resistance the shock absorber provides. Because of this feature, shock absorbers adjust to road conditions. As a result, shock absorbers reduce the rate of:
Jumping Rope – A skipping rope is the only piece of equipment involved in the program. If you don’t have one a piece of rope will do just fine. If you don’t have a piece of rope either jumping up and down on the spot without much bending in the knees will achieve a similar result. Jumping rope involves holding a rope with both hands and swinging it around your body continuously.
