At the competitive level (i.e., the NFL and NBA combines), vertical leap is measured using a “jump tester”—a tripod with a series of thin plastic sticks one inch apart. If you have access to this equipment, it’s your best bet for getting an accurate measurement. A cheaper, more feasible option is to do your jump next to a wall and mark the highest point you touch with a piece of chalk.
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.
The back squat and jump squat are the two most commonly-used strength training exercises for increasing vertical jump height. The back squat is clearly more effective for improving maximum force, while the jump squat can be used to shift the force-velocity gradient towards a more “velocity-oriented” profile when required. In addition, the jump squat has the secondary benefit of training force production right through until the muscles are contracting at short lengths, because of its longer acceleration phase. Even so, it is unclear whether squat variations are optimal for improving vertical jump height, because the center of mass is in a different place from in the vertical jump.
In 2004, as a high school senior, Candace Parker was invited to participate in the McDonald's All-American Game and accompanying festivities where she competed in and won the slam dunk contest.[51] In subsequent years other women have entered the contest; though Kelley Cain, Krystal Thomas, and Maya Moore were denied entry into the same contest in 2007.[52] Brittney Griner intended to participate in the 2009 McDonald's Dunk Contest but was unable to attend the event due to the attendance policy of her high school.[53] Breanna Stewart, at 6'3" (191 cm), Alexis Prince (6'2"; 188 cm), and Brittney Sykes (5'9"; 175 cm) competed in the 2012 contest; Prince and Sykes failed to complete their dunks, while Stewart landed two in the first round but missed her second two attempts in the final round.[54][55]
A predefined subgroup analysis was conducted according to the type of shock — septic shock, which occurred in 1044 patients (542 in the dopamine group and 502 in the norepinephrine group); cardiogenic shock, which occurred in 280 patients (135 in the dopamine group and 145 in the norepinephrine group); or hypovolemic shock, which occurred in 263 patients (138 in the dopamine group and 125 in the norepinephrine group). The overall effect of treatment did not differ significantly among these subgroups (P=0.87 for interaction), although the rate of death at 28 days was significantly higher among patients with cardiogenic shock who were treated with dopamine than among those with cardiogenic shock who were treated with norepinephrine (P=0.03) (Figure 3). The Kaplan–Meier curves for the subgroup analysis according to type of shock are shown in Figure 7 in the Supplementary Appendix.
El economista Tyler Cowen, quien llamó a la retórica de Klein "ridícula" y el libro un "verdadero desastre económico", dice que el libro contiene "una serie de proposiciones inventadas, tales como la idea de que Margaret Thatcher creó la crisis de las Islas Malvinas para aplastar a los sindicatos, y endosarle el capitalismo sin restricciones a un público británico poco dispuesto."18​

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.
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%).
Use a smaller ball. It's much easier, when you're first starting out, to try dunking with a smaller ball. You'll be able to palm it more easily and control your approach, making the maneuver more satisfying and your practice closer to the real thing. Continue dribbling and shooting exercises with the appropriate-sized ball so you're not getting too used to the "wrong" size, but keep a small ball around for your sick dunks.[1]
I paid a lot of money for a vertical leap training system in the past that was a total scam. The red flags were everywhere, but I overlooked them because I was so eager to train and get results. That's why I was tentative when I first found out about TTS and Coach Cascio. Not wanting to be ripped off again, I decided to thouroughly look through his website. I was surprised to see that he actually communicated with customers via social media and actually shared useful information and excercises for free with email, Youtube, and now this book. This honest approach made me feel confortable and so I decided to give his program a shot. Thanks a lot for working hard for us, Jack.
This study has several limitations. First, dopamine is a less potent vasopressor than norepinephrine; however, we used infusion rates that were roughly equipotent with respect to systemic arterial pressure, and there were only minor differences in the use of open-label norepinephrine, most of which were related to early termination of the study drug and a shift to open-label norepinephrine because of the occurrence of arrhythmias that were difficult to control. Doses of open-label norepinephrine and the use of open-label epinephrine and vasopressin were similar between the two groups. Second, we used a sequential design, which potentially allowed us to stop the study early if an effect larger than that expected from observational trials occurred; however, the trial was eventually stopped after inclusion of more patients than we had expected to be included on the basis of our estimates of the sample size. Accordingly, all conclusions related to the primary outcome reached the predefined power.
Scaling the back squat for beginner-level athletes generally entails sticking to lighter loads (even bodyweight only to start) while learning proper technique. Goblet squats with a kettlebell or dumbbell can be used to practice form, but keep in mind that goblets are an anterior (front-loaded) variation and won’t directly mimic the mechanics of the back squat.
Jumpsoles v5.0. The Jumpsoles are vertical jump shoes that fit onto your existing shoe. They are plyometric platforms that attach to your shoes and focuses your body weight onto your calves and train you to spring off the balls of your feet. By doing the special plyometric exercises in the video you develop fast twitch muscle fibers in your legs for explosive leaping improvement. Jumpsoles have been around for over 20 years and many players have increased their vertical jump with them. See real Jumpsoles reviews here.
As an athlete pushes off the ground, he or she must overcome his/her own body weight. The lighter the athlete, the less force is necessary to do this. Imagine trying to jump as high as you can and then immediately repeating this same test wearing a 20-pound vest. It's obvious that the second jump will be much smaller. Now, imagine how much higher you could jump if you were 20 pounds lighter.

I learned that insects are fucking awesome. There was an insect in particular that I was interested in called the froghopper, or spittlebug, that is basically one of the world’s top jumpers. It’s a survival mechanism. It can jump far, far higher than we can as a function of its weight, basically. So I learned that humans are quite modest in the jumping scheme of things.
Sets/Reps: For general strength and lower-body development, Benguche recommends 3–6 sets of 3–8 reps with moderate loading—70%–85% of your one-rep max (1RM). For developing more speed and power, he recommends lighter loads (55%–70% of 1RM) for 3–6 sets of 2–5 reps. Squats performed with light weights but done so explosively that your feet leave the floor when you come up are called jump squats (see “Progressions” below).

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.

On the basis of the results of the SOAP study,3 which showed a rate of death of 43% among patients receiving dopamine and a rate of 36% among patients receiving norepinephrine, we estimated that with 765 patients in each group, the study would have 80% power to show a 15% relative difference in the rate of death at 28 days, at a two-sided alpha level of 0.05.

By emphasizing certain muscles in your legs, you can train your body for the force needed to leap high. Increasing your vertical jump will improve your rebounding, blocking, dunking, and make you an all-around better basketball player. Here are a few of CoachUp’s favorite exercises for improving your leg strength and vertical jump. If you ever need extra motivation to get through these exercises on a daily basis, just re-watch these gifs and focus up!
In the tradition of New Year’s resolutions and the like, you can give yourself a year. I certainly didn’t want to give myself more than a year, because after a year I knew I would grow tired of it, and my body would start to get quite unhappy with me. But I would recommend to someone that they give it a go for at least six months. It’s also a way of just getting yourself in fantastic shape. I mean, trying to dunk a basketball in itself is awesome. It’s really great to be able to dunk a basketball, to get yourself higher up than you thought possible. But the process of getting yourself in that kind of position is itself rewarding.
The baseline dunk is an approach-modifier of any dunk type in which the player approaches the basket along the court-boundary (baseline) which runs parallel with the backboard. In the game setting, the dunk often comes as the result of a pass, creating an assist opportunity for a teammate. In the contest, the baseline approach may be used as a means of convenience, facilitating a particular dunk type (e.g., passes bounced off the side of the backboard or its padding) or to increase the difficulty of a dunk type in hopes of meriting higher scores.

Dunking (or attempting to dunk) is a high-impact, highly intense activity that deserves a sufficient warm-up prior to a throw-down session. Just as you would for a lifting workout, start your warmup with a few minutes of low-intensity cardio, then progress to more dynamic movements—dynamic stretching/mobility drills as well as jumping. Before attempting your first dunk, take a couple dry runs with no ball where you’re touching or grabbing the rim at the top.
An alley-oop dunk, as it is colloquially known, is performed when a pass is caught in the air and then dunked. The application of an alley-oop to a slam dunk occurs in both games and contests. In games, when only fractions of a second remain on the game or shot clock, an alley-oop may be attempted on in-bound pass because neither clock resumes counting down until an in-bounds player touches the ball. The images to the right depict an interval spanning 1/5 of a second.

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.
i am 6 foot 2 inches tall, i am in the 8th grade, and i am 13 years old going on 14 in september. I discovered on May 15th that I could hang on the rim at my school with two hands by jogging about 3 steps very very slowly and jumping off both of my feet. I have dunked about 3 times before, but the last couple times I tried, I got "hung" and sent backwards but I managed to keep balance on the way down due to my height. What is my problem? Also after I attempt to dunk about 4 times in a day my shin begins to hurt. Why does this keep happening?
Joe would die some 30 years later, at age 82, but what he said that day as he stood in a puddle of dry tobacco—his clothes disheveled, the other Fortenberrys yelping a chorus of excited Yessirs—spoke to me in a way that can only be understood by those who blindly take on missions that exact a greater toll than was envisioned. “Well,” he said with a grin, “that’s the last time I’ll ever do that.”
This is a dunk where the player takes off from a distance which is significantly further away from the basket than is considered typical. The free-throw line is most commonly constituted as the take-off point, an effect likely attributed to the easily observable span between the line and the basket in the view of the TV audience. In order to achieve the hang-time and altitude necessary, players will generally leap from one-foot to maximize the momentum generated from the half-court running start often required to complete the dunk. A cornerstone of dunk contests, dunks from a distance are also performed in games, most often on the fast break.
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.
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.
Sports scientist are able to measure these ground reaction forces with a technology called force plates. These plates record the exact forces occurring during a vertical jump (or any other movement) and allow you to see how quickly athletes can produce forces, how large these forces are, and to expose potential imbalances between the left and right leg.

There are a number of variations on the windmill, the most common being the aforementioned one- or two-hand variants. In these cases, the windmill motion may be performed with the previously discussed one-arm technique and finished with one- or two-hands, or the player may control the ball with two hands, with both arms performing the windmill motion, finishing with one or both hands. Additionally, the ball may be cuffed between the hand and the forearm—generally with the dominant hand. The cuff technique provides better ball security, allowing for a faster windmill motion and increased force exerted on the basket at finish, with either one or both hands. Using the cuffing method, players are also afforded the opportunity of performing the windmill motion towards the front (counterclockwise), a technique exploited by French athlete Kadour Ziani when he pioneered his trademark double-windmill.
Unfortunately, I’m not the 6' 7" son of a Hall of Famer, so I had to resort to desperate devices—like Hennessy, an infamous and inexpensive cognac that, according to one of the two NBA players who recommended it to me, “will give you that Yah! That bounce. That little bit of meanness you need.” The little minibar-sized bottle that I downed 30 minutes into an intense session of dunk attempts on a sweltering day last summer, had no effect other than scorching my esophagus, giving me a headache and releasing from my pores an aura that, as my six-year-old put it that evening, “smells like medicine.”
Even so, the back squat does differ in important ways from the vertical jump. Primarily, it involves a much greater trunk extension turning force, because of the barbell weight on the upper back, and this likely contributes to the more hip-dominant nature of the squat over the vertical jump. Secondly, it is often performed to a deeper depth, which can alter the relative contribution of each of the hip extensors to the movement, because of their different leverages at each joint angle. And thirdly, it only involves accelerating up to midway through the movement, while the vertical jump involves accelerating right up until take-off. This also affects the relative contribution of the hip extensors, as force production will be required in the jump even when the hip is nearly fully extended, while this is unnecessary in the squat.
The opening scene finds Modern Messiah Malcolm Stevens (the tragically deceased Jon Dough recreating his career-defining character) back in his familiar padded cell. Out of thin air, his lost lady love Gwen (Jeanna Fine, resplendent in stylized Marilyn Monroe Kabuki make-up) appears as an echo of the original's psychiatric theory that Stevens concocted his entire past out of years of transfixed TV ogling à la Jim Carrey's CABLE GUY. This proves to be the film's first of many technical knockouts, shot in black and white complete with scratches and splices to suggest an old movie, the tiniest splash of pink occurring as Jeanna vibrates herself into a frenzy. Malcolm still has a problem projecting himself into his own fantasies and is, at first almost subliminally, replaced by tattooed muscle boy John Decker, the mesmerizing lead from Paul Thomas' terrific MARISSA.
Darryl Dawkins of the Philadelphia 76ers was notorious for two glass-shattering dunks in 1979 resulting in the league threatening to fine him and eventually installing breakaway rims.[42] Twice in his rookie season (1992–93) during games, center Shaquille O'Neal dunked so hard that he broke the hydraulic support of one goal standard (against the Phoenix Suns) and broke the welds holding up another goal standard, causing the basket to break off and fall to the floor (against the New Jersey Nets), although in neither case did the glass break. This resulted in reinforced backboard supports as well. During that same season, New Jersey's Chris Morris shattered a backboard in a game against the Chicago Bulls (the most recent shattered-backboard incident in the NBA to date). The NBA has made shattering the backboard a technical foul, although it will not count towards a player's count of seven that can draw a suspension, or two towards ejection from a game, and it counts towards a player's count of six personal fouls. This has assisted in deterring this action, as it can cost the team points.
An important component of maximizing height in a vertical jump is attributed to the use of counter-movements of the legs and arm swings prior to take off, as both of these actions have been shown to significantly increase the body’s center of mass rise. The counter-movement of the legs, a quick bend of the knees which lowers the center of mass prior to springing upwards, has been shown to improve jump height by 12% compared to jumping without the counter-movement. This is attributed to the stretch shortening cycle of the leg muscles enabling the muscles to create more contractile energy. Furthermore, jump height can be increased another 10% by executing arm swings during the take off phase of the jump compared to if no arm swings are utilized. This involves lowering the arms distally and posteriorly during the leg counter-movements, and powerfully thrusting the arms up and over the head as the leg extension phase begins. As the arms complete the swinging movement they pull up on the lower body causing the lower musculature to contract more rapidly, hence aiding in greater jump height.[5] Despite these increases due to technical adjustments, it appears as if optimizing both the force producing and elastic properties of the musculotendinous system in the lower limbs is largely determined by genetics and partially mutable through resistance exercise training.[6][7]
