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]
Thus, dopamine and norepinephrine may have different effects on the kidney, the splanchnic region, and the pituitary axis, but the clinical implications of these differences are still uncertain. Consensus guidelines and expert recommendations suggest that either agent may be used as a first-choice vasopressor in patients with shock.6-8 However, observational studies have shown that the administration of dopamine may be associated with rates of death that are higher than those associated with the administration of norepinephrine.3,9,10 The Sepsis Occurrence in Acutely Ill Patients (SOAP) study,3 which involved 1058 patients who were in shock, showed that administration of dopamine was an independent risk factor for death in the intensive care unit (ICU). In a meta-analysis,11 only three randomized studies, with a total of just 62 patients, were identified that compared the effects of dopamine and norepinephrine in patients with septic shock. The lack of data from clinical trials in the face of growing observational evidence that norepinephrine may be associated with better outcomes called for a randomized, controlled trial. Our study was designed to evaluate whether the choice of norepinephrine over dopamine as the first-line vasopressor agent could reduce the rate of death among patients in shock.
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.
I have to admit...I bought this for my 5 year old son, but I found it to be just as enjoyable! Setup took a matter of minutes before he was launching his first rocket in the air. he was impressed with the THUMP followed by a dissapearing act as it launched into the sky. After he had a few tries it was my turn, I assumed it would not handle my 200lb frame very well so I started light and worked my way up to an all out double foot stomp that left craters where I landed. The SQUEEEEEL from my son as the rocket nearly "went to the moon" was priceless. We lost a few rockets that day to rooftops, damage from landing on pavement, and one down a difficult to repeat sewer drain. I advise to have the little ones wear safety ... full review
A total of 1679 patients were enrolled — 858 in the dopamine group and 821 in the norepinephrine group (Figure 1). All patients were followed to day 28; data on the outcome during the stay in the hospital were available for 1656 patients (98.6%), data on the 6-month outcome for 1443 patients (85.9%), and data on the 12-month outcome for 1036 patients (61.7%). There were no significant differences between the two groups with regard to most of the baseline characteristics (Table 1); there were small differences, which were of questionable clinical relevance, in the heart rate, partial pressure of arterial carbon dioxide (PaCO2), arterial oxygen saturation (SaO2), and ratio of partial pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FIO2). The type of shock that was seen most frequently was septic shock (in 1044 patients [62.2%]), followed by cardiogenic shock (in 280 patients [16.7%]) and hypovolemic shock (in 263 patients [15.7%]). The sources of sepsis are detailed in Table 2 in the Supplementary Appendix. Hydrocortisone was administered in 344 patients who received dopamine (40.1%) and in 326 patients who received norepinephrine (39.7%). Among patients with septic shock, recombinant activated human protein C was administered in 102 patients in the dopamine group (18.8%) and 96 patients in the norepinephrine group (19.1%).
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?
In the ABA, Charlie Hentz broke two backboards in the same game on November 6, 1970 resulting in the game being called.[43] In the NCAA, Jerome Lane shattered a backboard while playing for Pitt in a 1988 regular-season game against Providence, and Darvin Ham did the same while playing for Texas Tech in a tournament game against North Carolina in 1996.
slang To be bested by someone in a spectacular fashion and/or in a way that is humiliating to one. In basketball, to "dunk on" a defender is to perform a slam dunk over them, a move often considered humiliating to the defender. Here's the part of the debate where she really got dunked on&he totally destroys her argument! Sit down, son, you just got dunked on.

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 way Arthur J. Daley and the other spectators at the Y felt when Fortenberry dunked—that’s how fans at the Oakland Arena felt on Feb. 12, 2000, when Vince Carter shoved his forearm into the rim and swung there by his elbow. What only the initiated noticed about Carter’s dunk was that if you froze him during his approach, he looked like Bob Beamon. Carter long-jumped some 12 feet, right foot leading the way, before landing for a nanosecond and blasting off into his two-footed ascent.

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.

Justifying these selfish, skewed priorities in my head as I stuffed a basketball into my backpack and pedaled away from our home would turn out to be one of the most formidable obstacles in my path. I must have whispered, What the f--- am I doing? as many times as I leaped toward one of the rusty rims scattered around the south Los Angeles beach community where we live. That latter number tallied somewhere around 5,000, according to my journal and 24-plus hours of video. Many of these jumps were attempted while wearing a weighted vest that pulled me downward, the same way that home pulled me sideways.
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.

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.
During the 1940s and 1950s, 7-foot center and Olympic gold medalist Bob Kurland was dunking regularly during games.[7] Yet defenders viewed the execution of a slam dunk as a personal affront that deserved retribution; thus defenders often intimidated offensive players and thwarted the move. Satch Sanders, a career Boston Celtic from 1960 to 1973, said:

Muscular strength and explosiveness must be developed in conjunction with flexibility if the athlete is to maximize the jumping ability and reduce the risk of injury to structures such as the Achilles tendon and knee ligaments. Flexibility, when achieved through focused stretching programs, will serve to increase the range of motion in the joints essential to jumping: the ankles, knees, and hips. A common muscular deficiency that plagues athletes who require well-developed leaping ability is a lack of flexibility and resultant strength imbalance between the quadriceps (thigh) muscles and the hamstrings, the pair of muscles responsible for the flexion and the extension of the knee. Proper stretching will assist the athlete in the maintenance of an approximate 3:2 ratio in the relative strength of the quadriceps to the hamstring. When there is a significant deviation from that proportion, the knee and the muscles themselves are at greater risk of injury.

Asher Price, a reporter at the Austin American-Statesman, spent a year of his life trying to find out and chronicled his quest to jam on a regulation hoop in the book The Year of the Dunk, which comes out in May. Price, who played coy about whether he was able to achieve his goal, spoke to Science of Us about what a rec leaguer would need to do to fly like a pro. (Spoiler: lots of squats and alley-oop attempts.)


Janik was available by text whenever I needed him, like my very own dunk training app. The important thing, he said, was to work out hard and smart. When my knees or back were sore, he advised lowering the weight for a few sessions and eliminating depth jumps. "Listen to your body," he told me. And I did: I took a day off here or there if I needed it; I added more weight when I felt good. When, after five weeks, I started to worry that I wasn’t going to dunk again, he kept me motivated. "Leg strength is the key. Squat deep. Ass to grass," he told me, unsympathetic to the known fact that squats are fucking terrible.
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.
As an athlete pushes off the ground, he or she must overcome his/her own body weight. The lighter the athlete, the less force is necessary to do this. Imagine trying to jump as high as you can and then immediately repeating this same test wearing a 20-pound vest. It's obvious that the second jump will be much smaller. Now, imagine how much higher you could jump if you were 20 pounds lighter.
“Put in the work. It’s muscle memory, first and foremost. Training­wise, people say, ‘You gotta do this, you gotta do that.’ I didn’t believe in that. I never worked on my legs in high school or middle school. I would just go through this routine over and over and over, visualizing that day when you dunk on the court. And then you live in that moment.”
In the tradition of New Year’s resolutions and the like, you can give yourself a year. I certainly didn’t want to give myself more than a year, because after a year I knew I would grow tired of it, and my body would start to get quite unhappy with me. But I would recommend to someone that they give it a go for at least six months. It’s also a way of just getting yourself in fantastic shape. I mean, trying to dunk a basketball in itself is awesome. It’s really great to be able to dunk a basketball, to get yourself higher up than you thought possible. But the process of getting yourself in that kind of position is itself rewarding.

At the competitive level (i.e., the NFL and NBA combines), vertical leap is measured using a “jump tester”—a tripod with a series of thin plastic sticks one inch apart. If you have access to this equipment, it’s your best bet for getting an accurate measurement. A cheaper, more feasible option is to do your jump next to a wall and mark the highest point you touch with a piece of chalk.


For taxonomic purposes it is an important distinction, but the modifiers discussed below are often considered dunk types in common parlance. This misconception is perhaps attributable to the modifier being the most salient component of the dunk from the perspective of the observer. However, each dunk modifier requires a dunk type to be a successful dunk—albeit the most-basic dunk type.


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.

This list of movements was compiled by a pair of trainers who know a thing or two about making athletes more explosive: Jason Benguche, assistant strength and conditioning coach for the Carolina Panthers (@movement_mogul on Instagram), works one-one-one during the season with the NFL’s most explosive quarterback, Cam Newton. And Firdose Khan (@dose_9), head trainer at Nine Innovations athlete training facility in Houston, has worked with such athletes as former NBA MVP Derrick Rose and NFLers Arian Foster, Braxton Miller, and Brian Cushing.
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.
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).

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!

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.
