The defining characteristic of the depth jump is that the jump is preceded with the strong eccentric (negative) muscle action caused by dropping down from a raised surface, as opposed to a standard box jump where you start on the floor. This makes the depth jump a true plyometric movement, where the muscles are stretched suddenly (by the impact of the landing), producing a powerful shortening of the muscle fibers.
The phrase "slam dunk" has entered popular usage in American English outside of its basketball meaning, to refer to a "sure thing": an action with a guaranteed outcome, or a similarly impressive achievement. This is related to the high probability of success for a slam dunk versus other types of shots. Additionally, to "be dunked on" is sometimes popularly used to indicate that a person has been easily embarrassed by another, in reference to the embarrassment associated with unsuccessfully trying to prevent an opponent from making a dunk. This ascension to popular usage is reminiscent of, for example, the way that the baseball-inspired phrases "step up to the plate" and "he hit it out of the park," or American football-inspired phrases such as "victory formation" or "hail Mary" have entered popular North American vernacular.
The following data were recorded every 6 hours for 48 hours, every 8 hours on days 3, 4, and 5, and once a day on days 6, 7, 14, 21, and 28: vital signs, hemodynamic variables (including systolic and diastolic arterial pressures, heart rate, central venous pressure, and, when possible, pulmonary-artery pressures), cardiac output, arterial and mixed-venous (or central venous) blood gas levels, doses of vasoactive agents, and respiratory conditions. Biologic variables, data on daily fluid balance, microbiologic data, and antibiotic therapy were recorded daily for the first 7 days and then on days 14, 21, and 28.
When tendons elongate to a greater extent during a jumping movement that is preceded by a countermovement, the muscle lengthens less. This produces two effects. Firstly, the greater elongation of the tendon means that more elastic energy is stored during the countermovement, which is then released in the subsequent jumping phase. Secondly, the smaller elongation of the muscle means that countermovement depth can be greater for the same shortening velocity in the subsequent jumping phase, because the muscle never lengthened that much to begin with. Since shortening velocity determines force, this allows the same muscle force to be produced, despite the larger joint range of motion.

Smaller observational studies have suggested that treatment with dopamine may be detrimental to patients with septic shock.3,9,10 However, Póvoa et al. reported a lower rate of death among patients treated with dopamine than among those treated with norepinephrine.25 In our study, which included more than 1000 patients with septic shock, there was no significant difference in the outcome between patients treated with dopamine and those treated with norepinephrine.
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.
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).
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.
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.
Secondly, in addition to the rate of force development, the size of the force itself produces a negative feedback effect on vertical impulse, because higher forces lead to faster accelerations, which in turn reduce the time spent producing force before take-off. This is *partly* why drop jumps tend to involve higher forces, shorter ground contact times, and yet similar jump heights to countermovement jumps.
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.

Perhaps the most popular obstruction-modified dunk is the Dubble-Up. Aptly eponymous of the its pioneer—T-Dub, an American dunker hailing from Minnesota—the Dubble-Up starts with a person standing before the basket, holding the ball above their head. The dunker approaches and leaps as though their groin would soar above just above the head and their legs around the stationary person. Just prior to clearing the person, the dunker will assume control of the ball with one or both hands, guide it under a raised leg, transferring it to the appropriate hand, clearing the ball-holder, raising the ball above the horizontal plane of the rim, and finally guiding it downward through the basket. While the Dubble-Up mimics a between-the-legs dunk, Kenny Dobbs and Justin Darlington have both performed an under-both-legs variant.
I mean, I think you can probably improve your vertical some in a month. I think, though, that for most normal people who aren’t teenagers who are trying out for their basketball team, who don’t have all that time on their hands, I think there’s a much saner way to go about it, where you’re steadily improving your vertical over a period of time. You know, there’s a lot of this kind of slightly crazy, kamikaze, self-improvement type of thing, whether it’s trying to jump higher or do anything else. I’m sure those things work to some extent, but it’s not the way I would have wanted to go about it.
As far as sequels go, Ninn learned a lesson from his ill-fated follow-up to SEX. Without even a second of flashback footage, he designed SHOCK to surpass LATEX in every respect. It succeeds in some ways. In others, it merely (ha !) equals or falls just below its immediately illustrious predecessor. Simply put, and you can quote me on this, if LATEX blew your mind, SHOCK will turn it inside out !

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.
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.
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.
For smaller guys much of the problem, and one I struggled with, is managing the ball. Like most guys my size I can palm a basketball if a grab it carefully, but realistically it isn’t going to happen without a little concentrated effort. Some of those big guys can make a basketball look like a volleyball, and they have no trouble getting hold of it and shoving it over the rim.

After four months of failing to pull off anything even resembling a real dunk, the planets aligned on Aug. 9: After at least 19 failed attempts that afternoon, I dunked a soccer ball on a middle school court whose rim measured 9' 11". (The original basketball, incidentally, was a soccer ball, property of Dr. Naismith’s employer, Springfield College.) Video from that afternoon shows me standing there, looking confused, in the moment afterward. Did that just happen? Failing had become so routine that even this small success felt foreign.


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.

One morning a week later, the gym at the Y was empty. I picked up the same mini-ball and unsuccessfully tried to throw it down. I found the more relad I was, the higher I could jump. So I loosened my shoulders, took a depth breath, and approached the rim. I held the ball for a beat longer this time, and easily popped it over the rim. It felt incredible. I did it a few more times, each easier than the last, pulling down on the rim with unnecessary force for maximum satisfaction. But as exhilarating as it was to dunk again, I was only using a mini-ball—I hadn’t completely reached my goal.
Early in my mission, my editor had given me a book, Jump Attack, by Tim Grover, personal trainer to Jordan, Dwyane Wade and myriad other NBA stars. I’d ignored it at first; I figured I knew plenty about how to jump higher. When I finally opened it last December, I was further dissuaded. The exercises Grover prescribed to increase one’s vertical leap looked either nonsensical (hold a deep lunge for 90 excruciating seconds, without moving) or sadistic (the series of rapid-fire bursts and landings that he’d named “attack depth jumps”). These self-immolations, Grover wrote, would last for three months.
In the 1950s, Jim Pollard[28] and Wilt Chamberlain[29] had both dunked from the free throw line—15 feet from the basket. Chamberlain was able to dunk from the free-throw line without a running start, beginning his forward movement from within the top half of the free-throw circle.[29] This was the catalyst for the 1956 NCAA rule change which requires that a shooter maintain both feet behind the line during a free-throw attempt.[30]

The method described above is the most common and simplest way to measure one's vertical jump, but other more scientifically accurate methods have been devised. A pressure pad can be used to measure the time it takes for an athlete to complete a jump, and then using a kinematics equation (h = g × t2/8),[4] the computer can calculate his or her vertical jump based on the time in the air.
