“There aren’t many people in the world who can [dunk], that’s why it has this allure, I guess,” Carter told me last fall, during his first training camp with the Grizzlies. “As far as trying to do it, there are so many ways people can go about it. The approach you’re taking is the right approach. When I was younger, that’s how I started. Tennis ball, to the point that it became easy. Then a volleyball. Then a girls’ ball. Finally I took—it was like a dodgeball. I dunked that and said, ‘You know what, I’m gonna try it.’ Next thing you know. . . .” He shrugged and smiled, the gray whiskers on his jaw sinking into a dimple.
I sent a video of my soccer ball dunk to Todd, the #fivefivedunker, who informed me that I was leading with the wrong leg. I’d been taking my last big step with my left foot, which, as a righty, was like swinging a bat cross-handed. A few days later I encountered a blogger and 43-year-old dunker named Andy Nicholson who showed me, among many other things, that I wasn’t the only one with blood on my hands. Nicholson was one of dozens of YouTubers, young and old (mostly young), who were documenting online their attempts to dunk. “Yes!” he yelled over the phone when I told him about the open sores on my fingers. “Those are badges of honor!”
Dunking isn't for everybody, but many men at least have a chance at pulling it off. Even so, it depends on a lot of variables for those on the fringe. Many guys have excess weight that keep them grounded. Some days your legs just aren't up to it. Other days, you don't have the right shoes on, or a certain basketball is hard to grip, or a past injury is hampering you. Little things like that can keep you from basketball glory when you're oh-so-close to throwing down.
Among patients with cardiogenic shock, the rate of death was significantly higher in the group treated with dopamine than in the group treated with norepinephrine, although one might expect that cardiac output would be better maintained with dopamine26-28 than with norepinephrine. The exact cause of the increased mortality cannot be determined, but the early difference in the rate of death suggests that the higher heart rate with dopamine may have contributed to the occurrence of ischemic events. Whatever the mechanism may be, these data strongly challenge the current American College of Cardiology–American Heart Association guidelines, which recommend dopamine as the first-choice agent to increase arterial pressure among patients who have hypotension as a result of an acute myocardial infarction.7
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.
The force-velocity relationship during muscle shortening occurs because the number of simultaneously attached crossbridges between the myofilaments inside the working muscle fibers determine the amount of force that a fiber can produce. The number of attached crossbridges at any one time is dependent upon the fiber shortening velocity, because the detachment rate of the crossbridges at the end of their working stroke is higher at faster shortening speeds.
We have two diferent vertical jump bands that you can use as a volleyball player. The first bands are the M.V.P. Pro bands that are attached at the heels and a belt around the waist. These vertical jump bands can be worn during practice so everytime you jump your are improving your vertical with the resistance provided by the bands. These bands are best if you are 5' 6" or taller.
To get your training started, you need a way to measure your jump. If you’re testing your vertical at gym or in a professional type setting, they may have a Vertec. The Vertec is one of the most common apparatus for measuring vertical jump ability. It is the vertical jump-testing device of choice for many college and professional teams, but they also have the budget for such a thing. If you’re wanting to test your vertical in a budget-friendly way, you can easily use a measuring tape, a marked wall, or chalk for marking a wall.
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.
Generally, a player can reach their highest when jumping off one foot and reaching up with one hand. For a player that is right-handed, the most common way is approaching from the left and jumping off the left foot with the ball in the right hand. Obviously, for a left-handed player, it’s coming from the right and jumping off the right with the ball in your left hand.
I was under the impression that only tall people have the sole leverage of dunking well. This book proved me wrong. The book contains strategically laid out chapters with step by step jumping techniques. My friend have always wanted to play basketball but always held back due to his low height. With this book, there is no more stopping for him. There are also wonderful tips for improvisation. This is learning and beyond.
My early efforts were clumsy. Jumping willy-nilly as high as I could, with no regard for technique, I occasionally felt my finger graze the underside of the rim. Most times I did not. What I did feel early on was a firm self-awareness that I was a two-foot jumper (like Spud Webb, Dominique Wilkins, Vince Carter and myriad NBA Slam Dunk champions with whom I have nothing else in common athletically) as opposed to a one-foot jumper (see: Julius Erving, Clyde Drexler, Michael Jordan). This meant that my best shot at dunking would be to elevate like an outside hitter in volleyball—that is, by stepping forward with one foot, quickly planting my trailing foot next to it and then propelling myself upward off both.
these shocks make a big difference in handling and ride on the2015 4wd F250. This will make the suspension work rather than the whole vehicle simply shuddering up and down over small bumps and holes in the road. Tires stay in contact with road, suspension moves, you and the seat stay still, what a concept! OEM shocks don't even move once compressed, pityful. You will need an 18 mm wrench or socket for lower shock mount bolts and a 21 mm open end, box end or deep socket for the top mount nut and a 20mm or adjustable wrench for the shaft bolt on the top mount. Once the old shocks are off, you need a 19mm open end or socket for the Bilstein top mount nut and you hold the shaft from moving with a hex key, in my experience I didn't really need that but you may want to. Check the top of the shaft you'll see a hex hole up there, seems like it was a 6mm but don't hold me to that. Forget any jacking, removing tires, etc to do this it isn't necessary, and much safer with wheels on the ground while you are under there. If you need some space I drove the wheel I was working on over a 2x12 and that gave me a little height to work with. I wasn't in the mood to fool with jacks, jack stands and all that. No need to. Just crank the steering wheel over away from the side you are working on and you'll have plenty of room. The only issue is after attaching the lower shock mounts using the OEM 18mm bolt/nut, you need to compress the shock about 3" to get it into the upper mounting hole. I used a common tie down racheting strap for this job. I hooked one hook to the chassis right under the lower shock mount bracket on the truck and after adjusting the strap length I put the upper hook around the top shock rubber grommet and washer (lower one already installed now, put upper ones on after shock is in place, of course). At this point you just crank the rachet on the strap until the shock compresses a few inches and shove the shaft under the mounting hole, release the rachet and up pops the shock into place. Put on upper grommet and washer, tighten 19mm nut and presto! IF the shaft turns while you tighten this nut hold the shaft still with the hex key mentioned earlier. Your truck is now a better place to be. Also just tighten upper nut until the grommet fills or slightly goes outside the washer, don't crank it down and flatten the grommet. If you aren't sure look at the OEM arrangement for an idea on how tight to go with that nut. Happy motoring !!
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.
Though improving jumping technique may add a couple inches to an athlete's vertical jump, good landing technique is even more crucial. The landing is when almost every jumping-related injury occurs, not the jump itself. For this reason, athletes should spend a significant amount of time learning to land in a balanced position that distributes the impact of the jump equally across all joints of the lower body. This position should look almost identical to the take-off position.
To begin, go up without a ball first. This will give you a great idea of where you’re at and just how close you are to being able to dunk. For beginners, you should focus on dunking with one hand. Your other hand should stay by your side to balance your body while you’re in the air. The two-handed dunk is awesome, but is surprisingly more of an advance dunk and should be an approach you build up to as you work on your dunking.
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.
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.”
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. Colloquially, the dunk has a variety of names including 'honey dip', 'cookie jar', and 'elbow hook'.
If you make these few exercises a part of your basketball training, you’ll be well on your way to increasing the height of your vertical jump. Be sure to measure your jump height regularly in order to track your progress -- set goals for yourself each week and remain committed. Before long, you’ll be jumping higher and seeing noticeable improvements in your basketball game.
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!
High pulls can also be done using a dumbbell or kettlebell,. When doing so, position the weight between your feet and pull with one arm at a time (switching arms halfway through the set). A trap bar (aka, hex bar) is also an option, particularly for individuals who have a hard time keeping the lower back flat; the trap bar allows the hands to be positioned behind the shins to help pull the shoulders back.
Then you need to hold the chalk in your right hand, and then you need to jump from the same starting position (without a run-up). To do the jump, you’ll need to flex (bend) at the hip and knee joints and use your arms for momentum. At the top of the jump you’ll mark the wall (or chalk board) with the chalk. The score for the jump is the difference between the standing height and the jump height (in cm). The highest of three separate trials is recorded as your max score.
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.
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.
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.
If you can jump high enough to dunk, but you’re having a hard time going up with the basketball in one hand, the solution is to start small and work your way up. A smaller ball such as a soft golf ball or tennis ball is a great starting point. From there, move slowly to a mini-basketball. It will provide more of a challenge but still be easy to palm as you go up. Once you can dunk the mini ball, try moving on to a volleyball until finally a regulation basketball.
If you took a poll of the areas athletes wanted to improve the most, their vertical jump would be among the tops. Athletes playing basketball and volleyball rely on their verticals in a number of ways, but one major way is it gives them an edge to stand out amongst their peers. Players want to jump higher and coaches are looking for players that can put some space between their feet and the court.
Turn on the windmill. As you approach, bring the ball into your abdomen and back, extending your arm behind your body and up in a circular fashion, like a windmill spinning. At the apex of your jump, bring your arm all the way around to throw it down like a boss. Dominique Wilkins, the Dunkmaster General of the 90s, used to blow crowds away with this spectacular dunk.
Also, using the lifting (concentric) phase of these exercises only, rather than both lowering and lifting phases, *might* further improve results. This is partly because lifting phases involve faster rate coding, and partly because this strategy might potentially help avoid optimizing stretch-shortening cycle function for lifting heavy weights, rather than for jumping.
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. 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.
Dunking was banned in the NCAA from 1967 to 1976. Many people have attributed this to the dominance of the then-college phenomenon Lew Alcindor (now known as Kareem Abdul-Jabbar); the no-dunking rule is sometimes referred to as the "Lew Alcindor rule." Many others have also attributed the ban as having racial motivations, as at the time most of the prominent dunkers in college basketball were African-American, and the ban took place less than a year after a Texas Western team with an all-black starting lineup beat an all-white Kentucky team to win the national championship. Under head coach Guy Lewis, Houston (with Elvin Hayes) made considerable use of the "stuff" shot on their way to the Final Four in 1967.
My warmup on March 29, following a day of recovery, left me feeling hoppier than I’d expected, and not nearly as achy. After 10 devastating near misses, and several others that weren’t as close, Jeff lofted the best lob I would see during this journey. I leaped, controlled it with one hand and—boodaloomp—in and out. I could have wept. “You got this!” Jeff implored. “You know you got this!”
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.
variations: The vertical jump test can also be performed using a specialized apparatus called the Vertec. The procedure when using the Vertec is very similar to as described above. Jump height can also be measured using a jump mat which measures the displacement of the hips. To be accurate, you must ensure the feet land back on the mat with legs nearly fully extended. Vertical jump height can also be measured using a timing mat. The vertical jump test is usually performed with a counter movement, where there is bending of the knees immediately prior to the jump. The test can also be performed as a squat jump, starting from the position of knees being bent. Other test variations are to perform the test with no arm movement (one hand on hip, the other raised above the head) to isolate the leg muscles and reduce the effect of variations in coordination of the arm movements. The test can also be performed off one leg, with a step into the jump, or with a run-up off two feet or one foot, depending on the relevance to the sport involved. For more details see vertical jump technique.
