No, I think there’s a practical aspect to that. It’s hard to grip a basketball. I mean, that’s another physical challenge. I have pretty small hands, and one thing I had to train myself to do, which I couldn’t do at the start of this project, is palm a basketball. So that involved fingertip push-ups, to get the tips of your fingers much stronger. It involves, while hanging out and watching television, trying to palm a basketball for as long as you can. You want to get into a quick, full sprint, and you want to be able to grip the basketball as you go up to jam it. So doing those things can be a challenge. That’s partly what’s behind people doing the alley-oop-type things or throwing it up off the backboard. In some cases, they simply can’t grip the ball on the way to the hoop, so their solution is to throw it in the air, catch it, and try to bring it down.
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.
When I started to work on the video tool that measures vertical jump, I had to dust off my old textbooks to learn about the relationship between hang time and jump height. And to my surprise, it turned out that the vertical jump is a great (and interesting!) example of the laws of physics at work. You can really learn about the relationship between velocity, acceleration, forces and hang time. Definitely more interesting than the average example of your physics textbook!

Two foot jumpers spend a lot more time on the ground during take-off than one-foot jumpers. This allows them to generate a lot of force through the muscles of the calves, quads, glutes and hips. While one-foot jumpers rely heavily on elasticity and "bounciness", two-foot jumps are more reliant on strength and power. This is one of the reasons why football players are excellent two-foot jumpers - they have really strong lower bodies!


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.
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.
This isn’t just some light-duty assistance exercise. The rear-foot elevated split squat (aka, Bulgarian split squat) is a legitimate movement for increasing pure glute and quad strength, which will in turn enhance power and vertical jumping performance. Even if you’re a two-foot jumper, focusing on one leg at a time like you do here will ensure that your dominant side isn’t compensating for your weaker leg during the movement.
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.
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.
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.
My four year old son has a whole bunch of books in this series. They are all AWESOME. My son really likes facts and history and these books are full of both. You don't read them like a story - rather, they are basically written as one fact after another with lots of exciting illustrations in between. I like that I can jump around from fact to fact or picture to picture, depending on my son's mood or attention span at that particular point in time. He has actually been absorbing many of the names and dates and facts and statistics. I love that these books make it fun for kids to learn! FIVE STARS!!!

Dunking became a game again. After my closest misses I’d hop around and swear like a golfer whose playoff putt had lipped out. These outbursts were no longer harsh self-admonitions but celebrations of my progress, acknowledgements that I was getting tantalizingly close. I could feel my legs gaining in bounciness. I could feel my hips, quads and calves learning to fire simultaneously. My original lobber returned to the scene and suggested I try dunking in the morning instead of the evening, when the batteries in our old bodies are as low as the ones in our phones. I added this sage advice to the long list of micro­details “that help you steal inches,” as Todd had phrased it months earlier. “A quarter inch here, a half inch there.”
Parte 1, comienza y termina con un capítulo sobre psiquiatría y la terapia de choque, los experimentos encubiertos realizados por el psiquiatra Ewen Cameron en connivencia con la CIA: cómo fue un éxito parcial en la distorsión y regresión de la personalidad original de los pacientes, pero ineficaz en el desarrollo de una nueva personalidad mejor. Se hace un paralelismo con la terapia de choque económico, incluida una digresión sobre cómo los organismos gubernamentales se aprovechan de algunas de las lecciones aprendidas para crear más eficaces técnicas de tortura. La tortura, según Klein, a menudo ha sido una herramienta esencial para las autoridades que han aplicado las reformas agresivas del mercado libre y se hace hincapié en esta afirmación a lo largo del libro. Ella sugiere que por razones históricas el movimiento de derechos humanos ha retratado a menudo la tortura sin explicar su contexto, lo que ha hecho que con frecuencia aparecen como hechos inútiles de sadismo. El segundo capítulo presenta a Milton Friedman y su Escuela de Economía de Chicago, que Klein describe como líder de un movimiento comprometido con el libre mercado con las mismas regulaciones que antes de la Gran Depresión.

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.
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.

The simplest method to measure an athlete's vertical jump is to get the athlete to reach up against a flat wall, with a flat surface under his/her feet (such as a gym floor or concrete) and record the highest point he/she can reach flat-footed (the height of this point from the ground is referred to as "standing reach"); fingertips powdered with chalk can facilitate the determination of points touched on the wall. The athlete then makes an effort to jump up with the goal of touching the highest point on the wall that he or she can reach; the athlete can perform these jumps as many times as needed. The height of the highest point the athlete touches is recorded. The difference between this height and the standing reach is the athlete's vertical jump.
