The player approaches the basket and obstruction, and then leaps. During flight, some portion of the player's body is elevated above the obstruction. This may entail raising the legs or some portion thereof in-air to soar over the obstruction. In other instances, the trunk-moves over an obstruction as the legs pass around it. Common obstructions include: motor vehicles; crouched, seated or standing person(s); ball rack; or other available objects.

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.
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.

Single leg jumping with it's high impact forces and dependence on the elasticity of muscles and tendons works best for young athletes. With increasing age, the tendons and muscles lose their elasticity and springiness and the risk of injury gets higher and higher. That's why a lot of basketball players start to rely more and more on their two-foot jump as they get older. And the winner of the Olympic high jumping contest are almost always below 30.
March 27 was yet another in a long string of days, each feeling as if it would be the day. Fully rested and caffeinated, I arrived with Jeff at a court, recommended by Brent Barry, whose rim heights fluctuated but which I’d recently measured at 10 feet. The rims at New York City’s famed Rucker Park, incidentally, both measured under 9’ 9” on a recent visit, which raises all sorts of questions about what a dunk is and what it isn’t. The famed outdoor rims along Venice Beach, if lined up next to each other, would look like a graphic equalizer during a Ray Manzarek keyboard solo: 9' 9", 9' 11", 9' 8".
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.

Before you take on these vertical jump exercises, spend a few minutes looking over the plyometric section of our website. When you increase your vertical jump, you’re actually altering the nature of your muscle fibers, and our plyometric articles can explain how this works. Meanwhile, keep working on strength-building exercises for your quads, glutes and hips, and remember to keep an eye on any hesitation between your jumps.  
The Dual Shock Ver. served as the basis for the majority of ports, such as the Windows 9x-based PC-CD release, which was titled Resident Evil 2 Platinum in North America. Aside from retaining all previously added features, the PC version can be run in higher Display resolution.[1] A "Data Gallery" was also added to the main menu, allowing the player to view movies, rough sketches, illustrations and 3D models.[1]
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:
James Naismith, I learned, was a bit different. “I was only three when he passed away [in 1939],” said his grandson, James Naismith, 78, of Corpus Christi, Texas. “He was known as a tenderhearted man, but he also had”—the doctor’s namesake pauses—“the polite term is ‘firmness of mind.’ It’s kind of a family trait. He devoted his life to improving the lives of others through physical activity, through games. That took time.

Another aspect to look at for any potential dunkers is flexibility. I'm about 6'4 and 21. In high school, I, like many of you on here, worked on jumping and lifting to gain power. I had some decent strength, but the flexibility of a toothpick. Once I got out of high school and got more interested in fitness, I saw how much that affected me. If you can't touch your toes or only squat 8 inches down, this is a great place to start working on your flexibility.
after a certain age dunking becomes quite difficult to gain during the prime years 12 to 21 your body is still growing so it is easier to gain to muscle and muscle fiber to be able to dunk if you are quite short below 6ft it requires great effort to get the height to dunk the only exercises i suggest are one footed Calf Raises you can find how to do them on you tube and squats i was recommended these exercises by the Glasgow rocks coach and player Sterling Davis hope that helps i am 6ft myself and learning to dunk has been a long road and still going because i am only grabbing the rim now any more questions feel no fear to send me an email
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​
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.
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.
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.
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.
Another high pull option is to shorten the range of motion to make it a hang high pull instead of a power high pull (“power” implying that the load starts on the floor). In this case, the start position is from standing, with the bar hanging in front of your thighs at arms’ length. The movement is initiated with a dip in the hips and knees, so that the bar lowers to just above knee level, followed immediately by an explosive pull.

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 gave myself six months to dunk because that was the low end of the “six to eight months” prescribed on the website of Brandon Todd, a 5'5" former D-III star who set the same goal for himself in 2005, and then, at age 22, accomplished it. When I first contacted him, Todd perfectly expressed the more shallow reason behind my goal: “When you can dunk, it means you’re a good athlete. Period. It takes away any subjectiveness.” I also chose six months because, as would be proved repeatedly during this mission, I am prone to tragic spells of overconfidence.
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.
I tried to work out at least a couple of hours a day doing something or other. So some days were lifting, doing arm and core lifting. Again, you can imagine these sprinters, they’re strong all over — if you think of Tyson Gay or someone. It’s not just their legs that are muscular, it’s their arms, too, because they have to pump furiously to get themselves to go faster.
Among the hundreds of lessons I learned during my youngest child’s first year of life was this: If you earnestly pursue dunking after your athletic peak years of 18 to 30, give or take, it can be done. You can enjoy what it feels like to dunk. You can even feel it more purely than I did, maybe without needing a lob from a friend, and hopefully without all the hand damage. But you should expect a long, frustrating, demeaning war of attrition that pits mind, body, spirit against the most oppressive, unrelenting opponent of them all: gravity. The sun rises and sets, the tides creep in and out—even taxes and death seem negotiable nowadays—but gravity remains constant, forever pounding our shoulders, stooping us shorter as we grow gray, never letting up—no matter what NASA tweets.
“When most people first start trying to dunk, it’s usually off one leg,” says Jones. “You’re banking on your speed, so this means you want to have a running start to gain momentum. If you want to dunk off two, that requires more athletic ability, more coordination, and using the power dribble to gain momentum. If you have a nice set of calves and a big butt, this might be the way to go.”
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.
