Dunking exposes you to some extra risk of injury. First of all, you can get low-bridged or get your legs tangled up with defenders near the hoop, causing you to fall awkwardly from a significant height. You can also throw yourself off balance by trying to hang on the rim and slipping off, resulting in awkward falls. If you are in heavy traffic on the dunk, then being able to grab and hang on the rim until the clutter beneath you clears is a safety technique. If you are in the clear on a dunk, then avoiding hanging on the rim at all is the recommended safety technique (It's also a technical foul to hang on the rim in that situation). Whatever the situation, you need to come down with control and balance. Ankle, knee, neck, and head injuries await those who fail to control their momentum after a dunk.
Plyometrics is the best known of the jumping development exercise programs. Plyometrics training emphasizes speed and explosive movement, and a plyometrics program will typically consist of a series of bounding, hopping, and jumping drills. The object of a plyometrics program is to perform the exercises at maximum intensity. For this reason, plyometrics training must be approached with caution, and the athlete must progress slowly from one level to the next to reduce the risk of injury. Proper rest intervals must also be incorporated in to plyometrics training, as the exercises are intended to place significant stress on the target muscle groups.
Toe Raises – stand with your feet shoulder width apart, typically on stairs or any sort of ground you can stand on that allows your heel to dip down. Then raise up on the tips of your toes. Continue this process until your complete your reps. Don’t rock up and down – or go to fast. For the exercise to work, you have to use correct form and go at a steady pace.
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.

I'm 33 yrs old, turning 34 in a month. I stand 5'7" and weigh 155 lbs. I used to touch the rim with both hands but now I can only touch the back board... I almost came close to dunking, but that was when I was 22 years old. I still dream of dunking one in...but I think the exercises that I used to do...don't seem to work anymore... Is it still possible for me to dunk even at this age?

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.

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.
Aside from squats, the exercises below are considered some of the best bodyweight plyometrics you can do to help improve the fast-twitch muscle fibers that enable you to jump higher and run faster. When it comes to vertical jump, plyometrics are a key. A review in the "British Journal of Sports Medicine" looked at 26 research studies that tested the effects of plyometrics on vertical jumps and found that plyometrics increased vertical jump by 8 percent. Another study reported that plyometrics helped professional athletes increase their vertical leap by 23 percent, improve their agility by 8 percent, their balance by 5 percent, and their time by 0.30 seconds on the 20-meter sprint.
High Reach Jumps – with your feet shoulder width apart, bend down into a comfortable squat position and then jump up as high as you can reaching for the sky! This drill is great to do under the basketball goal or near a wall so you can have a visual of how high you’re jumping – or how low you jump once you start getting tired. Try to reach the same height through all your reps.

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?
Starting out, athletes should always err on the conservative side and only perform 10-20 maximal effort jumps in a training session. Because of the explosive nature of a vertical jump, the body can only perform a handful before performance starts to drop. Training beyond this point will not improve jumping height and will only lead to injury. At the completion of a training session, it is generally recommended to rest 48 hours before completing another intense training session.
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'.
For improving vertical jumping ability, the back squat and jump squat have been used for many years with great success. Depending on the exact force-velocity profile of the athlete, either back squats or jump squats should be effective for improving vertical jump height. Even so, exercises that shift the load towards the center of mass of the body, such as hex bar deadlifts and weighted vest jumps could be superior.

One morning a week later, the gym at the Y was empty. I picked up the same mini-ball and unsuccessfully tried to throw it down. I found the more relad I was, the higher I could jump. So I loosened my shoulders, took a depth breath, and approached the rim. I held the ball for a beat longer this time, and easily popped it over the rim. It felt incredible. I did it a few more times, each easier than the last, pulling down on the rim with unnecessary force for maximum satisfaction. But as exhilarating as it was to dunk again, I was only using a mini-ball—I hadn’t completely reached my goal.

Keep that in mind, and progress slowly. A mini basketball is a little more challenging than a tennis ball, but it's easy to palm and that helps. See if you can get high enough to get your hand over the rim--almost up to your wrist--so you can stuff the mini ball. If you can't throw it down with a little authority, a bigger basketball won't be any easier.

Dunking (or attempting to dunk) is a high-impact, highly intense activity that deserves a sufficient warm-up prior to a throw-down session. Just as you would for a lifting workout, start your warmup with a few minutes of low-intensity cardio, then progress to more dynamic movements—dynamic stretching/mobility drills as well as jumping. Before attempting your first dunk, take a couple dry runs with no ball where you’re touching or grabbing the rim at the top.
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.
As far as sequels go, Ninn learned a lesson from his ill-fated follow-up to SEX. Without even a second of flashback footage, he designed SHOCK to surpass LATEX in every respect. It succeeds in some ways. In others, it merely (ha !) equals or falls just below its immediately illustrious predecessor. Simply put, and you can quote me on this, if LATEX blew your mind, SHOCK will turn it inside out !
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.
The two-hand backscratcher finish can exert tremendous force on the basket. In 1979, Darryl Dawkins twice shattered NBA backboards with tomahawk dunks leading to a quickly-enacted rule making it an offence to break the backboard.[citation needed] Technology has evolved to adapt to the increased strength and weight of players to withstand the force of such dunks, such as the breakaway rim (introduced to the NBA in 1981) changes to the material used for the backboards, and strengthening of the goal standards themselves.
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.
Smaller observational studies have suggested that treatment with dopamine may be detrimental to patients with septic shock.3,9,10 However, Póvoa et al. reported a lower rate of death among patients treated with dopamine than among those treated with norepinephrine.25 In our study, which included more than 1000 patients with septic shock, there was no significant difference in the outcome between patients treated with dopamine and those treated with norepinephrine.

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.
In this multicenter, randomized trial, we assigned patients with shock to receive either dopamine or norepinephrine as first-line vasopressor therapy to restore and maintain blood pressure. When blood pressure could not be maintained with a dose of 20 μg per kilogram of body weight per minute for dopamine or a dose of 0.19 μg per kilogram per minute for norepinephrine, open-label norepinephrine, epinephrine, or vasopressin could be added. The primary outcome was the rate of death at 28 days after randomization; secondary end points included the number of days without need for organ support and the occurrence of adverse events.
A Tomahawk dunk can be performed with one or two hands, and when two hands are used, it is called a backscratcher. During the jump, the ball is raised above, and often behind the player's head for a wind-up before slamming the ball down into the net at the apex of the jump. Due to the undemanding body mechanics involved in execution, the tomahawk is employed by players of all sizes and jumping abilities.[citation needed] Because of the ball-security provided by the use of both hands, the two-handed tomahawk is a staple of game situations—frequently employed in alley-oops and in offense-rebound put-back dunks.
Stand with your feet shoulder-width apart. Keeping your back straight, bend at your knees and hips as if you are attempting to sit in a chair until your thighs are parallel with the floor. Simultaneously extend your arms straight out in front of you. From this position jump up, straighten your legs and swing your arms back down to the side of your body. Repeat 25 jumping squats in a row for three sets with a 1-minute break between sets.

Often times, basketball players have used one-leg jumping their whole life. It's just a much more natural movement because it's used every single time someone goes for a layup. On the other hand, volleyball players are often used to two-foot jumping because it is the most common way to jump when trying to block or spike. So, if you have all the suppositions to be a great two-foot jumper, but you get barely of the ground this way, it's probably because of a lack of technique.

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.
Using only a lifting (concentric) phase for strength training exercises could also be more effective for improving vertical jump height than traditional, stretch-shortening cycle exercises under load, for two reasons. Firstly, using only a lifting phase involves faster rate of force development through higher rate coding, and this may increase high-velocity strength more over the long-term. Secondly, doing stretch-shortening cycle exercises under load *might* cause the tendons to increase stiffness to a greater extent. This would make the muscle lengthen more in the countermovement phase of a jump, and thereby reduce muscle force for a given countermovement depth.
Hi, I’m Trevor Theismann and welcome back to the blog. Today we’ll be focusing on the vertical jump and looking for ways to jump higher and increase our vertical distance. We’ve demonstrated some vertical jump exercises on the blog in the past, but now let’s take a minute to talk about technique. Training your body to jump higher isn’t just a matter of reps and strength building. No matter how many box jumps you take on, your vertical distance isn’t likely to increase unless you’re building your jump reflex correctly.
I cannot honestly say that the program absolutely works since I have yet to execute it. However, I believe that the principles and exercises absolutely work. They are honed into a system by Mr. Grover and Attack Athletics. I believe Mr. Grover to be at the top in athletic training. His list of clients and their success speaks for itself. As far as the book goes...it looks like it was written in the stone ages! But once you get past its appearance and the stars of yesteryear that appear in the book...it has quality and value. Although I believe it to be somewhat overpriced (what isn't these days???), it can help an athlete get to the next level in sports performance! Do it!
Less helpful was my early realization that I was a two-hand dunker, in light of my inability to palm a basketball on the move. It’s common knowledge among dunkers that throwing down with two hands is typically harder than with one; the former requires a higher vertical leap. So as I flailed haplessly at the rim last spring with one hand, I felt not just discouragement but also fear. Fear that I would miss big chunks of my kids’ ninth, sixth, and first years on earth just so I could come up embarrassingly short on a senseless goal that my wife and I would later estimate consumed 15 to 20 hours a week, on top of my normal work hours. And fear that I had shared this idea with my editors way too soon.
Add some flair with a double-pump. Suggesting you're so high you could dunk it twice, in the double-pump dunk you bring the ball back down to chest level at the apex of your leap, then force it back up to slam it with authority. Some notable players, Tracy McGrady among them, would do this regularly while spinning in the air, doing a 360 dunk variation.
Yet, rate of force development is likely less important for vertical jumping than for faster athletic movements, such as sprinting. This is because the time that is available for force production is *ten times* longer in the vertical jump than in sprinting. Sprinters often take their foot off the ground before their lower body muscles have achieved maximum force (which takes approximately 150ms), but this early period of rising force production plays only a very small role during vertical jumping.
