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 amount of resistance a shock absorber develops depends on the speed of the suspension and the number and size of the orifices in the piston. All modern shock absorbers are velocity sensitive hydraulic damping devices - meaning the faster the suspension moves, the more resistance the shock absorber provides. Because of this feature, shock absorbers adjust to road conditions. As a result, shock absorbers reduce the rate of:
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.
I went through this progression, too. I went from touching the middle of the net at 12 years old, to dunking a basketball at 14 years old, to doing serious acrobatic 360-degree dunks at 17 years old. In college, my personal record for the vertical leap was 40 inches. At my peak, I was able to touch the top of the square on a regulation backboard, about 11.5 feet from the ground. Even now, in my thirties, I can dunk a basketball while standing underneath the basket—no run up required. I owe it all to the power of the vertical jump.
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.

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.
March 27 was yet another in a long string of days, each feeling as if it would be the day. Fully rested and caffeinated, I arrived with Jeff at a court, recommended by Brent Barry, whose rim heights fluctuated but which I’d recently measured at 10 feet. The rims at New York City’s famed Rucker Park, incidentally, both measured under 9’ 9” on a recent visit, which raises all sorts of questions about what a dunk is and what it isn’t. The famed outdoor rims along Venice Beach, if lined up next to each other, would look like a graphic equalizer during a Ray Manzarek keyboard solo: 9' 9", 9' 11", 9' 8".

Another aspect to look at for any potential dunkers is flexibility. I'm about 6'4 and 21. In high school, I, like many of you on here, worked on jumping and lifting to gain power. I had some decent strength, but the flexibility of a toothpick. Once I got out of high school and got more interested in fitness, I saw how much that affected me. If you can't touch your toes or only squat 8 inches down, this is a great place to start working on your flexibility.
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.
I just turned 14 year old 5''''10-5''''11 8th grade 165 pounds and i''''m wondering what stretching exercises and weight lifting exercises i can do to increase my vertical its already at like 30-32 inches but i want maybe a 40 by high school and a 48 or more by the time i''m out of high school i''ve dunked over 15 times ( in practice and alone with one hand its effortless to touch rim with both feet and easier with one but i''m also wondering how to take off when i dunk because i stutter step and i want to get my explosiveness up. And i want to be able to dunk with two hands. Can anyone help me?
When performing a vertical jump, the athlete exerts force at the low back, hip, knee, and ankle joints. The spine flexes as the athlete squats downwards, and then is extended by the spinal erectors over the course of the jump. The hip extensors (gluteus maximus, hamstrings, and adductor magnus) work to move the trunk and the thigh apart, which pushes the torso up and backwards. Meanwhile, the knee extensors (quadriceps) contract to extend the knee, and the calf muscles contract to move the shin backwards, towards the vertical.
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.
Janik was available by text whenever I needed him, like my very own dunk training app. The important thing, he said, was to work out hard and smart. When my knees or back were sore, he advised lowering the weight for a few sessions and eliminating depth jumps. "Listen to your body," he told me. And I did: I took a day off here or there if I needed it; I added more weight when I felt good. When, after five weeks, I started to worry that I wasn’t going to dunk again, he kept me motivated. "Leg strength is the key. Squat deep. Ass to grass," he told me, unsympathetic to the known fact that squats are fucking terrible.

In the Noble Asylum's control room, Dr. Hellstrom (a devastating portrayal by Ona Zee) is browsing through the reports of missing Lillian Mangrove (a welcome return for Tyffany Million), the now catatonic Stevens' psychiatrist who went missing right after first examining him. She has been found in a state of severe shock, nursed back to health at the institution and is currently running a psycho-tracking agency, kicking serious nut case butt in attempts to retrieve runaway crazies. Subscribing to the beneficial qualities of shock treatment (hence the title), Hellstrom reactivates Stevens who drags an innocent young nurse tellingly also named Gwen (succulent Shayla LaVeaux) into the dark recesses of his twisted mind, vowing to free her only if the doctors agree to discharge him from their madhouse...
Step 2. Nudge the bar out of the rack and step back, setting your feet at shoulder width, with your toes turned slightly outward. Without letting your feet actually move, try to screw both legs into the floor, as if you were standing on grass and wanted to twist it up—you’ll feel your glutes tighten and the arches in your feet rise. Take a deep breath into your belly and brace your core, pulling your ribs down so your torso forms a solid column.
We have two diferent vertical jump bands that you can use as a volleyball player. The first bands are the M.V.P. Pro bands that are attached at the heels and a belt around the waist. These vertical jump bands can be worn during practice so everytime you jump your are improving your vertical with the resistance provided by the bands. These bands are best if you are 5' 6" or taller.
Some players thinking jumping off two feet to be more comfortable, but it’s different for every player. Take time while you’re practice your jump to find what’s the most comfortable for you. As you’re learning the right way to jump, comfort is crucial because you don’t want to hurt yourself making a move that feels awkward. You want to be comfortable taking off and landing - and that can be done a number of different ways.

The loading phase of a vertical jump should look very similar to a Romanian dDeadlift—the only difference is the arm position. In this position, the weight is on the toes. The knees and ankles are slightly bent, the chest is leaned forward and the arms are extended just past the hips. In this position, the athlete can generate the most amount of vertical power.
“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.’ ”
Not so long ago, I played the worst basketball game of my life. I missed layups, turned over the ball, allowed my opponent free reign to the hoop. It was dark. As I slumped on the sidelines after the game, I realized how far I’d fallen from my prime a decade ago. Back then, I could dunk; now, at 33, I could barely curl my fingers over the rim. My game had regressed to hovering around the arc jacking threes. The last time I dunked a basketball, Michael Jordan was a Washington Wizard and people still listened to Coldplay.
slang To best someone in a spectacular fashion and/or in a way that is humiliating to them. In basketball, to "dunk on" a defender is to perform a slam dunk over them, a move often considered humiliating to the defender. The phrase is commonly used in a passive construction ("(one) got dunked on"). Here's the part of the debate where she really dunks on him by completely destroying his argument. You can't just tweet at this person and make fun of their opinion. If you really want to dunk on them, you have to correct their horrible grammar too.
Better still is an eye-popping nightclub sequence with a unique floor show, the undeniable visual highlight in a feature fraught with such. Malcolm mimics Joel Grey's M.C. from CABARET, introducing the "original" Gwen as Marilyn warbling a haunting song which effectively sums up the movie in its deceptively simple lyrics which I have included in the above summary. A gospel choir and hoop-skirted beauties (à la Madonna's iconic MTV Vogue appearance) surround lusty lovers Sean Rider and Sharon Kane at her most heartbreakingly vulnerable. The cum shot segues into the slow motion flutter of milky white doves John Woo style !
A vertical jump is defined as the highest point an athlete can touch from a standing point jump, less the height the athlete can touch from a standing position (standing reach height). The best place to start with your vertical jump improvement is testing your vertical jump. This will serve as your reference point to see how you’re increasing your vertical.

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]
During the takeoff an athlete generates forces that ultimately result in a vertical velocity high enough to leave the ground. We have shown before, that this vertical velocity reaches 0 at the peak of the jump, and it is easy to show that the velocity is exactly the same during landing as it was during takeoff (but directed in the opposite direction).

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.

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]

We purchased this because of its safety evaluation and the high ratings. I did evaluate the negative reviews and was prepared for the issues reported, however; I found none of the comments in the negative reviews to be valid with our experience. First, for the people who complained about the assembly instructions- there are pictures....yes, the English is horrible, but there are pictures! Total assembly time, with one human, was 2 hours and 10 minutes. Assembly of the safety cage was the the most difficult part. Specifically, the foam comes in two sections, which makes it difficult to slide into the pocket. BUT, with a little patience it can be done. Second, to those who would rather purchase a unit from Walmart- this is a very fine product, with consumer quality pieces, they include gloves, spring tool, and a ladder- you don't get ... full review
About 100 yards away from this 9' 10" breakaway rim (which came to sound, each time I grabbed and released it, like someone closing the metal baby gate at the top of our stairs) was a brown, oxidized, immobile 9' 1" version, a hand-ruining iron maiden where, in front of the occasional puzzled onlooker, I practiced (and practiced) the timing and the hand and wrist work required to dunk. I knew early on that my regulation dunk, if it ever came to pass, would have to come from a lob of some sort—a bounce to myself, either off the blacktop or underhanded off the backboard—after which I would hypothetically control the ball with one hand just long enough to flush it. Mastering the placement and the delicate timing of such lobs would prove to be a quixotic pursuit in and of itself. But it was necessary, not just because of my hand size (7 ¾ inches) but also because I needed to keep my arms free so I could swing them at takeoff, adding much-needed lift to my leap.
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.
