The force-velocity profile can be described by three elements: (1) maximum strength, (2) maximum velocity, and (3) the slope of the force-velocity gradient, because this is what determines whether the balance between force and velocity is optimal at the desired speed for force production. Each of these factors is an independent predictor of vertical jump height.
Mr Shaqy - your goal to dunk is good.... but, I want you to think about this.... watch some high school games and tell me how many dunks you see compared to a really good shooter especially from the arc. You have 3 more years of Middle School and there is lot more of your game to work on than just dunks.... good defense, good inside game at your height.... ball handling, passing and mid range shots..... 3s if you can do that.
Still, by the late 1950s and early 1960s players such as Bill Russell and Wilt Chamberlain had incorporated the move into their offensive arsenal. The dunk became a fan-favorite, as offensive players began to aggressively intimidate defenders with the threat of vicious slams. Through the 1970s, the slam dunk was standard fare; David Thompson, Julius Erving, Darryl Dawkins, and others wowed crowds with high-flying moves.
If you make these few exercises a part of your basketball training, you’ll be well on your way to increasing the height of your vertical jump. Be sure to measure your jump height regularly in order to track your progress -- set goals for yourself each week and remain committed. Before long, you’ll be jumping higher and seeing noticeable improvements in your basketball game.
The boundary for stopping the trial owing to the lack of evidence of a difference between treatments at a P value of 0.05 was crossed (Figure 5 in the Supplementary Appendix). There were no significant differences between the groups in the rate of death at 28 days or in the rates of death in the ICU, in the hospital, at 6 months, or at 12 months (Table 2). Kaplan–Meier curves for estimated survival showed no significant differences in the outcome (Figure 2). Cox proportional-hazards analyses that included the APACHE II score, sex, and other relevant variables yielded similar results (Figure 6 in the Supplementary Appendix). There were more days without need for the trial drug and more days without need for open-label vasopressors in the norepinephrine group than in the dopamine group, but there were no significant differences between the groups in the number of days without need for ICU care and in the number of days without need for organ support (Table 3). There were no significant differences in the causes of death between the two groups, although death from refractory shock occurred more frequently in the group of patients treated with dopamine than in the group treated with norepinephrine (P=0.05).
When I was growing up, basketball was big in my neighborhood. Everyone wanted to be able to dunk on a regulation 10-foot high basket and, thus, everyone focused on improving their vertical jump. The progression usually went a little something like this: touch the rim, grab the rim, hang on the rim, dunk with a volleyball and, finally, dunk with a basketball!
Improve your flexibility by stretching. Stretch your hamstrings and buttocks by laying on your back with one leg crossed over the other at the knee. Pull the lower leg toward you firmly and steadily. This should stretch the hamstring of the crossed leg. For another exercise, touch your toes while seated, standing, with your legs spread, and with your legs crossed.
Though improving jumping technique may add a couple inches to an athlete's vertical jump, good landing technique is even more crucial. The landing is when almost every jumping-related injury occurs, not the jump itself. For this reason, athletes should spend a significant amount of time learning to land in a balanced position that distributes the impact of the jump equally across all joints of the lower body. This position should look almost identical to the take-off position.
An impressive vertical jump is the ultimate standard of lower-body power and explosiveness—an attribute that pays as many dividends in high-impact sports like basketball, football, and soccer as it gets you wide-eyed looks in the gym. Increase your hops, and chances are you’ll also be able to run faster, lift more weight, and maybe even throw down a dunk at your next pickup basketball game.
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.
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.
I am in grade 10, 15 years old and 6'1 3/4". I have big hands and can palm the ball...I could touch rim in grade 8 and getting closer to dunking everyday now..it literally takes no effort to touch rim now but whenever I go for the dunk I get the ball above rim easily but have trouble getting that wrist motion to actually throw the ball in the hoop...and help?

After warming up, I proceeded to slam Jeff’s best lobs off the back rim at least 10 times, watching these missed dunks rebound high over the lane and land somewhere near the three-point line. It’s tough to express how difficult it was to pack up and walk away from the court on such days, to listen to my body when it told me it had reached the point of diminishing returns. To come up with yet another way to tell the wife: No, not today, Sugar. But I came reeeally close.
Randomization was performed in computer-generated, permuted blocks of 6 to 10, stratified according to the participating ICU. Treatment assignments and a five-digit reference number were placed in sealed, opaque envelopes, which were opened by the person responsible for the preparation of the trial-drug solutions. The solutions of norepinephrine or dopamine were prepared in vials or syringes according to the preference of the local ICU. Each vial or syringe was then labeled with its randomly allocated number. The doctors and nurses administering the drugs, as well as the local investigators and research personnel who collected data, were unaware of the treatment assignments. The trial was approved by the ethics committee at each participating center. Written informed consent was obtained from all patients or next of kin.
The things I had going for me: an understanding spouse; a modicum of foot speed and leaping ability, flashed during the occasional Motrin-supported pickup game; proximity to one of the best training centers in the world; and, again, an understanding spouse. The forces working against me made for a longer list and included (but were far from limited to) my average hand size and arm length, a lower-back injury that I suffered while playing semipro football in 2009 and my age. I was 42.
Start with a ping-pong ball, then a tennis ball, then a softball, then a volleyball, then a youth-sized basketball, and on up until you can dunk with a regulation size ball. If you can't palm the ball, then you will need to learn how to control the ball with two hands until the last minute extension for the dunk with one hand, or you will have to jump high enough to dunk two-handed.
slang To be bested by someone in a spectacular fashion and/or in a way that is humiliating to one. In basketball, to "dunk on" a defender is to perform a slam dunk over them, a move often considered humiliating to the defender. Here's the part of the debate where she really got dunked on&he totally destroys her argument! Sit down, son, you just got dunked on.
Because of the foam edges the fear of scraping your shins are gone so you can go harder but also because of the foam it is a little unstable when you jump to the 30" level. Instead of scraping my shin on the edge, the foam made the base a little unstable and the box kicked out. Luckily I was on a mat and not a hard floor. That is the only problem I saw with this box.

Whether the result of a 180° spin or body angle at takeoff, the double clutch is generally performed with the player's back toward the rim. While this orientation is rather conducive to the double clutch motion, Spud Webb was known to perform the dunk while facing the basket. Additionally, Kenny "Sky" Walker, Tracy McGrady—in the 1989 and 2000 NBA Contests, respectively—and others, have performed 360° variation of the double clutch (McGrady completed a lob self-pass before the dunk). Circa 2007, independent slam dunker T-Dub performed the double clutch with a 540° spin which he concluded by hanging on the rim.
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. It is considered a type of field goal; if successful, it is worth two points. Such a shot was known as a "dunk shot" until the term "slam dunk" was coined by former Los Angeles Lakers announcer Chick Hearn.
Rope skipping is also a very basic form of a type of exercise called plyometrics. Plyometric exercises involve repetitive explosive movements, such as jumping up and down or catching and throwing a medicine ball. The idea is to execute the movement with as little downtime as possible between repetitions. This, in effect, trains muscles to be powerful and explosive, and utilize the kinetic energy inherent in athletic movements in the most efficient way.
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 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.
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.
