In the past, it has been possible for players to dunk a basketball and pull the rim down so hard that the glass backboard shatters, either around the rim itself or, at times, shattering the entire backboard, or the entire goal standard fails. Reinforced backboards and breakaway rims have minimized this at the college and professional levels, but it still happens at lower levels.

A vital part of basketball training is improving your vertical leap. As an athlete, you should be incorporating exercises into your basketball drills and fitness training that focus on increasing muscle strength and leg speed. Simply put, you won’t turn into Vince Carter or Andre Iguodala overnight, but learning how to work the appropriate muscles on a daily basis will go a far way towards improving your overall vertical.
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.
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.

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.
In the 2008 Sprite Rising Star's Slam Dunk Contest Dwight Howard performed the "Superman" dunk. He donned a Superman outfit as Orlando Magic guard Jameer Nelson tied a cape around his shoulders. Nelson alley-ooped the basketball as Howard jumped from within the key side of the free throw circle line, caught the ball, and threw it through the rim. This dunk is somewhat controversial, as his hand was not over as well as on a vertical plane to the rim. Some insist that it should in fact be considered a dunk because the ball was thrust downward into the basket, meeting the basic definition of the dunk.
I went through this progression, too. I went from touching the middle of the net at 12 years old, to dunking a basketball at 14 years old, to doing serious acrobatic 360-degree dunks at 17 years old. In college, my personal record for the vertical leap was 40 inches. At my peak, I was able to touch the top of the square on a regulation backboard, about 11.5 feet from the ground. Even now, in my thirties, I can dunk a basketball while standing underneath the basket—no run up required. I owe it all to the power of the vertical jump.
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.
This is a high quality gear set for the next generation recoil shock series.  They only use one gear set through out the entire range, so this will fit all NEXT gen guns. This is a extremely well made piece of kit, This is possibly one of the strongest gear sets on the market, i would say the main benefit over other gear sets is its tuning option, you can by it in both single torque which is a little over the standard gear ratio and the double torque which is a lot over the standard ratio. Both provide increased torque up on the gun ie less effort to turn the spring, which in turn gives you increased battery life and and faster trigger response, sacrificing a little ROF. Although technically they should see a decrease in ROF because of the ratio, ive actually seen increases in ROF because of how efficient these gears are and because they are balanced.  Expensive gears but a very awesome piece of kit if these where cheaper they would no doubt be in ever ones guns.. no exceptions.
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 vertical jump is one of the most explosive physical movements executed in sport. In a number of sports, the higher the athlete is able to jump, the greater the prospects of success in that discipline. Basketball and volleyball are the two most prominent examples of sports where that correlation is plain. The jumping ability of an athlete is also an indicator of overall athletic ability, as there is a clear relationship between the ability to jump and the running speed that the athlete will develop over short distances. The National Football League, where prospective players are subjected to various physical tests, requires every player to be tested for both vertical leaps and 40-yd (37 m) sprints, irrespective of the position played.

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
Whichever equipment you use, the first thing you’ll need to do is measure your reach standing flat-footed on the floor with one arm fully extended straight overhead. (You can measure your reach up against a wall for the chalk option.) Then, when you mark the highest point you touched, you’ll subtract your reach from that number. For example, if your reach is 90 inches and you touched 115 inches up on the wall with your chalk, your vertical leap is 25 inches.
Increase your vertical leap. You will need the lifting power of your legs to get you in the air and up to the basket. Building a regimen of leg workouts that will increase the fast-twitch strength and the flexibility of your leg muscles can help you add inches to your vertical leap, getting you that much closer to the rim.[2] A good regimen to get started with might include:
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​
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.
