In the 2011 NBA contest, Los Angeles Clippers power-forward Blake Griffin completed a self-pass off of the backboard prior to elbow-hanging on the rim. A number of other variants of the elbow hang have been executed, including a lob self-pass, hanging by the arm pit,[23] a windmill,[24] and over a person.[25] Most notable are two variations which as of July 2012, have yet to be duplicated. In 2008, Canadian athlete Justin Darlington introduced an iteration aptly entitled a 'double-elbow hang', in which the player inserts both forearms through the rim and subsequently hangs on both elbows pits.[26] Circa 2009, French athlete Guy Dupuy demonstrated the ability to perform a between-the-legs elbow hang; however, Guy opted not to hang on the rim by his elbow, likely because the downward moment could have resulted in injury.[27]

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.
Athletes often do depth jumps with two plyo boxes: one to step off of and another to jump onto. Essentially, it’s a depth jump into a box jump. When doing this variation, make sure to leave enough room between the boxes to allow you to land and jump safely (3–5 feet between boxes should work). To advance within this progression, increase the height of the second box gradually as you develop more strength and power.
Shocks work and the ride is much better but installing them is a pain. They don't come compressed and are hard to compress by hand. For a 2012 F250 I bolted the lower portion of the shock up then took a racket strap and hooked it around the top bolt collar. Racket it till its close to the hole then release the strap and knock it over in the hole. That was the way I did it. The first side took forever trying to muscle it in then I busted out the strap and had it on in 5min.........Good product but I wish it would have came compressed.
Try calf raises for an easy way to exercise your calves. In a standing position, push on the balls of your feet while raising your heels so that you’re standing on your toes. Hold this position for 1-3 seconds, then slowly lower yourself back down to starting position. Do 10 reps, or as many as you can, and do as many sets as needed to complete 30 reps overall.[4]
A slam dunk, also simply dunk, is a type of basketball shot that is performed when a player jumps in the air, controls the ball above the horizontal plane of the rim, and scores by putting the ball directly through the basket with one or both hands.[1] It is considered a type of field goal; if successful, it is worth two points. Such a shot was known as a "dunk shot"[1] until the term "slam dunk" was coined by former Los Angeles Lakers announcer Chick Hearn.[2]
Four times a week, from April through October, I embarked on 90-minute explosive weightlifting sessions based on the years I’d spent working as a strength coach to club, college and professional volleyball players. Squats, squat jumps, deadlifts, lunges, box jumps, cleans, sprints. . . . Three or four days a week I visited one of my local blacktops, where I tried to dunk tennis balls on 10-foot rims or throw down basketballs and volleyballs on lower ones. By May 3—one month in—I could dunk a tennis ball on a 9' 10" rim. I considered this a better-than-good start, not realizing that compared to dunking a basketball, this tennis-ball jam was akin to a child scrawling the diagonal line that begins a capital A on his first day of learning the alphabet.
Because jumping ability is a combination of leg strength and explosive power, jumping can be developed in the same fashion as any other muscular activity. The ultimate limit to how high any athlete can jump will be determined to a significant degree by the distribution of fast-twitch versus slow-twitch fibers present in the muscles of the legs. This distribution is a genetic determination. Fast-twitch fibers are those whose governing neurons, the component of the nervous system that receives the impulses generated by the brain to direct muscular movement, fires more rapidly, which in turn creates the more rapid muscle contractions required for speed. As a general proposition, an athlete with a greater distribution of fast-twitch fibers will be able jump higher than one with a preponderance of slow-twitch fibers.
We conducted this multicenter trial between December 19, 2003, and October 6, 2007, in eight centers in Belgium, Austria, and Spain. All patients 18 years of age or older in whom a vasopressor agent was required for the treatment of shock were included in the study. The patient was considered to be in shock if the mean arterial pressure was less than 70 mm Hg or the systolic blood pressure was less than 100 mm Hg despite the fact that an adequate amount of fluids (at least 1000 ml of crystalloids or 500 ml of colloids) had been administered (unless there was an elevation in the central venous pressure to >12 mm Hg or in pulmonary-artery occlusion pressure to >14 mm Hg) and if there were signs of tissue hypoperfusion (e.g., altered mental state, mottled skin, urine output of <0.5 ml per kilogram of body weight for 1 hour, or a serum lactate level of >2 mmol per liter). Patients were excluded if they were younger than 18 years of age; had already received a vasopressor agent (dopamine, norepinephrine, epinephrine, or phenylephrine) for more than 4 hours during the current episode of shock; had a serious arrhythmia, such as rapid atrial fibrillation (>160 beats per minute) or ventricular tachycardia; or had been declared brain-dead.
I found out that if you practice penultimate two-step jumping practice dunking or just jumping, it gives a MUCH better workout than any one step jumping practice. I was also able to increase my one foot jump vertical by this. I think 2-step dunking is much more powerful and waaaaaay cooler. It is also much safer because you are in more control of your body. Right now I'm 6'1" and can 2-step tomahawk and basically everything off one foot
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 first thing they have to do is improve their flexibility, for a couple of reasons. They need to be flexible to undertake the kind of exercises they need to be able to jump higher. They also just need to be able to increase their flexibility, because in the short sprints you take when you try to dunk a basketball, if you can imagine yourself running up to try to dunk on the rim, the higher you can bring your knees in a sprint, just like a sprinter running the hundred meters, the greater force you’ll be able to exert on the ground, especially with your leaping step.

Go between the legs. While he wasn't the first player to complete it, Vince Carter wowed crowds at the 2000 NBA dunk contest by passing the ball under one leg while in the air and slamming it with authority. It didn't hurt that his forehead was almost touching the rim. If you've worked your ups to that height, try passing it under one leg and dunking it.
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]
