In the 2011 NBA contest, Los Angeles Clippers power-forward Blake Griffin completed a self-pass off of the backboard prior to elbow-hanging on the rim. A number of other variants of the elbow hang have been executed, including a lob self-pass, hanging by the arm pit,[23] a windmill,[24] and over a person.[25] Most notable are two variations which as of July 2012, have yet to be duplicated. In 2008, Canadian athlete Justin Darlington introduced an iteration aptly entitled a 'double-elbow hang', in which the player inserts both forearms through the rim and subsequently hangs on both elbows pits.[26] Circa 2009, French athlete Guy Dupuy demonstrated the ability to perform a between-the-legs elbow hang; however, Guy opted not to hang on the rim by his elbow, likely because the downward moment could have resulted in injury.[27]
I am 5''11 with a 43 inch vertical I am a freshman and I play on the varsity team as a point gaurd I can do 360''s and now a 540 I want to tell you how I can dunk all I did was watch Vince carter and watch the motion he does and I did the same motion and I never thought I could dunk until the beginning year of 8th grade now I am a freshman posterizing 11 and 12th graders.
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.
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.
El Premio Nobel y ex economista jefe del Banco Mundial, Joseph Stiglitz, escribió una reseña de La doctrina del shock para el New York Times, llamando al paralelismo entre la terapia de choque económico y los experimentos psicológicos realizados por Ewen Cameron "sobredramático y poco convincente" y afirmando que " Klein no es una académica y no puede ser juzgada como tal. Hay muchos lugares en su libro donde se simplifica en exceso." Sin embargo afirma que "la cuestión en contra de estas políticas es aún más fuerte que la que Klein hace" y que el libro contiene "una rica descripción de las maquinaciones políticas necesarias para obligar a desagradables políticas económicas en los países en resistencia."2​ Paul B. Farrell del Dow Jones Business News afirmó que "hay que leer lo que puede ser el libro más importante sobre la economía en el siglo 21".3​ John Gray escribió en The Guardian: "Hay muy pocos libros que realmente nos ayudan a comprender el presente. La doctrina del shock es uno de esos libros."4​ William S. Kowinski del San Francisco Chronicle escribió: "Klein podría haber revelado la narrativa de nuestro tiempo",5​ y fue nombrado uno de los mejores libros de 2007 por el Village Voice, Publishers Weekly,6​ The Observer,7​ y Seattle.8​ El irlandés Times describe los argumentos de Klein como "peso" junto a los informes del Dr. Tom Clonan: "sistemáticamente y con calma se muestra al lector" la forma en que los neoconservadores estaban íntimamente ligadas a los eventos sísmicos que "dieron lugar a la pérdida de millones de vidas". Cerca del final de la revisión del Dr. Clonan, ofrece una síntesis de que el argumento central de Klein es que el proyecto neoconservador no se trata de "la implantación de la democracia", sino una receta represiva por la maximización del beneficio global para una pequeña élite. "Los neoconservadores ven como ideal la proporción de super-ricos/pobres permanentemente ligada a una súper clase de oligarcas empresariales y sus compinches políticos que son el 20%". El 80% restante sería la población del mundo, los pobres "desechables", que subsisten en la "miseria planificada", que no pueden pagar una vivienda adecuada, la educación o la asistencia sanitaria privatizada.9​
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.
If anything came to surprise me about this journey, it was the sheer volume of physical pain involved. I had taken on impressive physical feats before. I had run a sub-3:30 marathon back in 2003 (my first and only attempt) after put­ting in the hundreds of training miles required. I’d done some of the most grueling weight training on offer, most of it either on the beach or at The Yard, a nearby temple of athletic performance where Maria Sharapova, Kobe Bryant and Tom Brady, among many others, have kneeled with exhaustion. But the physical toll of trying to dunk made the marathon and the semipro football and the parenting and everything else I’d ever attempted seem like mere rubber band snaps to the wrist. The lifting didn’t hurt as much as the jumping, the banging of my quadragenarian appendages into the ground, taking off and landing 50 to 200 times a day. My legs never got used to this bludgeoning, never got better at recovering from it, despite my daily foam-rollering, stretching, icing and hydrating. Even on my off days, a quick game of tag with my kids or a bike ride to the park meant daggers in my thighs and a gait like Fred Sanford’s.

Early in my mission, my editor had given me a book, Jump Attack, by Tim Grover, personal trainer to Jordan, Dwyane Wade and myriad other NBA stars. I’d ignored it at first; I figured I knew plenty about how to jump higher. When I finally opened it last December, I was further dissuaded. The exercises Grover prescribed to increase one’s vertical leap looked either nonsensical (hold a deep lunge for 90 excruciating seconds, without moving) or sadistic (the series of rapid-fire bursts and landings that he’d named “attack depth jumps”). These self-immolations, Grover wrote, would last for three months.

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.
Technique Tip: Determining how far out in front of you to place your front foot may require some trial and error. At the bottom of the motion, your front knee should be somewhere above your heel to mid foot. If your knee is behind your heel, your foot is too far forward; if it’s out over your toes, step out further. One trick to find the right distance is to start in the bottom position and adjust your stance from there. Then stand up and have someone hand you the dumbbells.
Try calf raises for an easy way to exercise your calves. In a standing position, push on the balls of your feet while raising your heels so that you’re standing on your toes. Hold this position for 1-3 seconds, then slowly lower yourself back down to starting position. Do 10 reps, or as many as you can, and do as many sets as needed to complete 30 reps overall.[4]
Original shocks have a secocnd lower nut that prevents the shock rod from spinning when loosening or tightening the upper mounting nut. The Bilstein shocks are not equipped with the second nut and the shock rod turns while trying to tighten the upper mounting lock nut, making it impossible to tighten. I had to return the shocks and bought a different brand. Also, Bilstein's installation instructions are about the worst I have ever seen.
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.
Tomorrow night, Brooklyn’s Barclays Center will host the annual NBA Slam Dunk Contest as part of the league’s All-Star Weekend. Dunking a basketball is generally reserved for seasoned athletes with the incredible vertical leap required to rise high enough to stuff a ball through a ten-foot rim. But what about the aging average Joes who grew up watching high-flying stars like Dominique Wilkins and Michael Jordan? Could they ever soar high enough to achieve the dream of every schoolyard baller in the country?
A strut is a major structural part of a suspension. It takes the place of the upper control arm and upper ball joint used in conventional suspensions. Because of its design, a strut is lighter and takes up less space than the shock absorbers in conventional suspension systems. Struts perform two main jobs. First, struts perform a damping function like shock absorbers. Internally, a strut is similar to a shock absorber. A piston is attached to the end of the piston rod and works against hydraulic fluid to control spring and suspension movement. Just like shock absorbers, the valving generates resistance to forces created by the up and down motion of the suspension. Also like shock absorbers, a strut is velocity sensitive, meaning that it is valved so that the amount of resistance can increase or decrease depending on how fast the suspension moves.

In summary, although the rate of death did not differ significantly between the group of patients treated with dopamine and the group treated with norepinephrine, this study raises serious concerns about the safety of dopamine therapy, since dopamine, as compared with norepinephrine, was associated with more arrhythmias and with an increased rate of death in the subgroup of patients with cardiogenic shock.

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 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

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.
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.
Similar to building explosive power by jumping over a stationary object, hurdles allow you to practice your leap. Space eight flights of hurdles two feet from each other and aim to jump over each like a pogo stick—basically, as high as you can. Repeat this for 10 repetitions: one flight of eight hurdles equals one repetition. Do this twice per week.
The method described above is the most common and simplest way to measure one's vertical jump, but other more scientifically accurate methods have been devised. A pressure pad can be used to measure the time it takes for an athlete to complete a jump, and then using a kinematics equation (h = g × t2/8),[4] the computer can calculate his or her vertical jump based on the time in the air.
