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.

The rate of death at 28 days in this study was close to 50%, which is to be expected in a study with very few exclusion criteria and is similar to the rate in previous observational studies.3,9,21-24 Our trial was a pragmatic study that included all patients who were treated for shock states, and therefore, it has high external validity. The study design allowed for maximal exposure to the study drug, since we included patients who had received open-label vasopressors for a maximum of 4 hours before randomization and since during the 28-day study period, the study drug was withdrawn last when patients were weaned from vasopressor therapies and was resumed first if resumption of vasopressor therapy was necessary.


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.

“No, not Dad,” Oliver said in the brick tract home where he grew up. “He was an older dad, like you, and his family was the focus of his life. The only time he wasn’t home with us kids was when he went out on the road for Phillips Petroleum, buying and selling leases in western Kansas and Oklahoma. When he got back he’d say, ‘All I wanted to do was come home.’ ”
To build strength in the legs that will be compatible with the speed developed through successful plyometrics drills, squat and lunge exercises are important components. Squats are performed with free weights, where the athlete uses a weighted bar to carry out the exercise. The additional weight will be supported by the body through the abdominal, lumbar (low back), and gluteal muscles, in addition to the legs. This form of exercise permits the strengthening of the legs in conjunction with enhancing the core strength of the body, essential to the balance necessary to have the several muscle groups involved in leaping work in harmony.
Hi, I’m Trevor Theismann and welcome back to the blog. Today we’ll be focusing on the vertical jump and looking for ways to jump higher and increase our vertical distance. We’ve demonstrated some vertical jump exercises on the blog in the past, but now let’s take a minute to talk about technique. Training your body to jump higher isn’t just a matter of reps and strength building. No matter how many box jumps you take on, your vertical distance isn’t likely to increase unless you’re building your jump reflex correctly.
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.
Using only a lifting (concentric) phase for strength training exercises could also be more effective for improving vertical jump height than traditional, stretch-shortening cycle exercises under load, for two reasons. Firstly, using only a lifting phase involves faster rate of force development through higher rate coding, and this may increase high-velocity strength more over the long-term. Secondly, doing stretch-shortening cycle exercises under load *might* cause the tendons to increase stiffness to a greater extent. This would make the muscle lengthen more in the countermovement phase of a jump, and thereby reduce muscle force for a given countermovement depth.
In this multicenter, randomized trial, we assigned patients with shock to receive either dopamine or norepinephrine as first-line vasopressor therapy to restore and maintain blood pressure. When blood pressure could not be maintained with a dose of 20 μg per kilogram of body weight per minute for dopamine or a dose of 0.19 μg per kilogram per minute for norepinephrine, open-label norepinephrine, epinephrine, or vasopressin could be added. The primary outcome was the rate of death at 28 days after randomization; secondary end points included the number of days without need for organ support and the occurrence of adverse events.
When an individual has a force-velocity gradient angled such that force is too high and velocity is too low, they benefit most from high-velocity strength training exercises with light loads. Conversely, when an individual has a force-velocity gradient angled such that force is too low and velocity is too high, they benefit most from low-velocity strength training exercises with heavy loads. Often, individuals with a long history of heavy strength training display profiles that are not ideal for vertical jumping, because their force is too high, and their velocity is too low, so they need to focus on high-velocity strength training.
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

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.
variations: The vertical jump test can also be performed using a specialized apparatus called the Vertec. The procedure when using the Vertec is very similar to as described above. Jump height can also be measured using a jump mat which measures the displacement of the hips. To be accurate, you must ensure the feet land back on the mat with legs nearly fully extended. Vertical jump height can also be measured using a timing mat. The vertical jump test is usually performed with a counter movement, where there is bending of the knees immediately prior to the jump. The test can also be performed as a squat jump, starting from the position of knees being bent. Other test variations are to perform the test with no arm movement (one hand on hip, the other raised above the head) to isolate the leg muscles and reduce the effect of variations in coordination of the arm movements. The test can also be performed off one leg, with a step into the jump, or with a run-up off two feet or one foot, depending on the relevance to the sport involved. For more details see vertical jump technique.

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.


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.
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.”

Among patients with cardiogenic shock, the rate of death was significantly higher in the group treated with dopamine than in the group treated with norepinephrine, although one might expect that cardiac output would be better maintained with dopamine26-28 than with norepinephrine. The exact cause of the increased mortality cannot be determined, but the early difference in the rate of death suggests that the higher heart rate with dopamine may have contributed to the occurrence of ischemic events. Whatever the mechanism may be, these data strongly challenge the current American College of Cardiology–American Heart Association guidelines, which recommend dopamine as the first-choice agent to increase arterial pressure among patients who have hypotension as a result of an acute myocardial infarction.7


Hi im Deontay i been trying 2 dunk ever since 7th grade and i know i been improveing since 7th grade i could touch the bottom of the backboard and i guest i was 5'6 or 5'7 at the end of the 8th grade i started exercising by having a 150 pound bag of cement on my shoulders and started squats and i try 2 15 wit a extra 5 at ever exercise i do but i still c very little effects so when went 2 my last day of school i could touch rim easily but the rim was about 8 foot and i was 5'9 now im a freshmen at my high school and i grip 10 foot rim wit my fingers not wit my hands but wit my fingers and im at 5'10 and im only 15 and i think my growing sprout is kicking in but anyway i want 2 know how can i get the ball over the rim and pound it in like d.rose king james and blake griffin i could grip the ball all i need 2 know is how 2 jump high enough 2 have that ball above the rim and pound it in will u please help
Before and after every workout, stretch your legs. This can lead to increase flexibility which loosens your muscles and allows them to perform better with a greater range of motion. In other words, they are strong and function better. Be sure to include dynamic stretches into your warm-up to get your joints moving and static stretches into your cool down after the workout.
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.
In this multicenter, randomized, blinded trial comparing dopamine and norepinephrine as the initial vasopressor therapy in the treatment of shock, there was no significant difference in the rate of death at 28 days between patients who received dopamine and those who received norepinephrine. Dopamine was associated with more arrhythmic events than was norepinephrine, and arrhythmic events that were severe enough to require withdrawal from the study were more frequent in the dopamine group. In addition, dopamine was associated with a significant increase in the rate of death in the predefined subgroup of patients with cardiogenic shock.
This calculator tells you how much you need to jump to dunk a basketball. It will also give you an estimated force required to jump that high. The more you bent your knees the less force you'll need but you will need a lot of energy to take you from that position to the top. You can increase your vertical by training your legs to be able to deliver that much force.

Strength exercises include slow, controlled movements like squats, lunges, and weighted step-ups.  Power exercises require explosive, quick moves like those needed for plyometrics and power cleans. Plyometrics are explosive bounding, hopping and jumping drills that blend strength and speed. Finally, practicing maximum vertical jump will increase vertical jump.
