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.

Because of the possible combinations of starting and finishing hands, and raised-legs, there are many variations on the basic under-the-legs dunk—more so than any other.[17] For example, in a 1997 French Dunk contest, Dali Taamallah leapt with his right leg while controlling the ball with his left hand, and once airborne he transferred the ball from his left hand, underneath his right leg to his right hand before completing the dunk.[18] NBA star Jason Richardson has also pioneered several notable variations of the between-the-legs including a lob-pass to himself[19] and a pass off of the backboard to himself.[20] Independent athlete Shane 'Slam' Wise introduced a cuffed-cradle of the ball prior to initiating the under the leg transfer and finishing with two-hands.[21] While a number of players have finished the dunk using one- or two-hands with their backs to the rim, perhaps the most renowned variant of the dunk is the combination with a 360°, or simply stated: a 360-between-the-legs. Due to the athleticism and hang-time required, the dunk is a crowd favorite and is heralded by players as the preeminent of all dunks.[citation needed]


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.

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.
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.
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.

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?


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.
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.
Rope skipping is also a very basic form of a type of exercise called plyometrics. Plyometric exercises involve repetitive explosive movements, such as jumping up and down or catching and throwing a medicine ball. The idea is to execute the movement with as little downtime as possible between repetitions. This, in effect, trains muscles to be powerful and explosive, and utilize the kinetic energy inherent in athletic movements in the most efficient way.
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.
The following data were recorded every 6 hours for 48 hours, every 8 hours on days 3, 4, and 5, and once a day on days 6, 7, 14, 21, and 28: vital signs, hemodynamic variables (including systolic and diastolic arterial pressures, heart rate, central venous pressure, and, when possible, pulmonary-artery pressures), cardiac output, arterial and mixed-venous (or central venous) blood gas levels, doses of vasoactive agents, and respiratory conditions. Biologic variables, data on daily fluid balance, microbiologic data, and antibiotic therapy were recorded daily for the first 7 days and then on days 14, 21, and 28.
A forceful, dramatic move, as in That indictment was a slam dunk if ever there was one. This expression is also often put as a verb, slam-dunk, meaning "make a forceful move against someone," as in This is a great chance for us to slam-dunk the opposition. The idiom comes from basketball, where it refers to a dramatic shot in which the ball is thrust into the basket from above the rim. It was transferred to other activities from about 1980 on.

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.
In fact, if you are a very short player and can barely reach the net when you jump you should probably put the dream of dunking the ball out of your mind. Better to spend time working on your layups and ball-handling skills. You can still lift weights and do all the other things to increase your vertical leap, and you can still be a very effective player.

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.


From Jordan to Lebron, even Yao Ming, nothing elicits more awe and applause than a dunk. As one of the highest percentage field goals one can attempt in basketball, this is a move that's worth mastering. While it doesn't hurt to be taller, you can build up both the muscles and skills required to execute this famous feat on the court, regardless of your height and experience. See Step 1 for more information.
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.
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.”
To perform two-foot dunks, jumpers bend their knees very deeply and spend a lot more time on the ground loading the jump. This increased time during takeoff is useful because it allows the athlete to transfer force into the ground thereby improving height. Using this approach makes it more difficult to transform speed into jump height making a fast approach far less useful than in one-foot jumping.

Klein respondió en su página web a Norberg afirmando que había tergiversado su enfoque. Klein sostiene que Norberg usa argumentos sin base, al afirmar que su libro es sobre un hombre, Friedman, mientras que en realidad trata sobre una "tendencia multifacética ideológica".21​ Norberg respondió que "se defiende solamente de una de las críticas que le hice. Da la impresión de que acabó por intentar encontrar pequeños errores aquí y allá en su libro."22​
For one-footed jumpers, the ball is generally transferred to the non-dominant hand just before or upon take-off; for two-footers, this transfer is often delayed for milliseconds as both hands control the ball to prevent dropping it. Once airborne, the dunker generally transfers the ball from non-dominant to dominant hand beneath a raised leg. Finally, the ball is brought upwards by the dominant hand and slammed through the rim.
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.
To start the test, you need to stand with your right side against a wall. If you have access to a chalk board or a vertex (the measuring tool used by biokineticists), it makes this easier, however, you can use an outside wall. For the first marking, stand in your training shoes with your right hip against the wall. Reach up with your right hand to touch the wall at the highest point possible (while keeping your heels flat on the ground). Mark this point with chalk, as this is your “standing height.”
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%).
A second, more efficient and correct method is to use an infrared laser placed at ground level. When an athlete jumps and breaks the plane of the laser with his/her hand, the height at which this occurs is measured. Devices based on United States Patent 5031903, "A vertical jump testing device comprising a plurality of vertically arranged measuring elements each pivotally mounted..." are also common. These devices are used at the highest levels of collegiate and professional performance testing. They are composed of several (roughly 70) 14-inch prongs placed 0.5 inches apart vertically. An athlete will then leap vertically (no running start or step) and make contact with the retractable prongs to mark their leaping ability. This device is used each year at the NFL scouting combine.
