Other binary end points were analyzed with the use of chi-square tests, and continuous variables were compared by means of an unpaired Student's t-test or a Wilcoxon rank-sum test, as appropriate, with the use of SPSS software, version 13.0 (SPSS). All reported P values are two-sided and have not been adjusted for multiple testing. The study statistician and investigators remained unaware of the patients' treatment assignments while they performed the final analyses.
The vertical jump is defined as the highest point that the athlete can touch from a standing jump, less the height that the athlete can touch from a standing position. The measurement of the jump is flawed if the athlete is permitted to take one or more steps before jumping, as the athlete will convert some of the energy developed in the step taken into the force of propulsion that generates upward lift. Basketball has numerous legends and other urban myths concerning the seemingly superhuman leaping ability attributed to certain players; one such player, former University of Louisville star Darrell "Dr. Dunkenstein" Griffith, was reputed to possess a 42 in (1 m) vertical leap. It is likely that the average National Basketball Association player 6 ft 6 in (1.97 m) or shorter has a vertical leap of between 25 and 30 in (0.63 and 0.75 m); taller and heavier players will usually not be able to jump as high.

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.
In the 2000 NBA Slam Dunk Contest Carter used an elbow hang along with his reverse 360 windmill dunk and between-the-legs dunk. When performed, much of the audience was speechless, including the judges, because none had seen these types of dunks before (Carter's first round 360 windmill dunk is reminiscent of Kenny Walker's 360 windmill dunk in 1989 except that Carter spins clockwise, whereas Walker spins counter-clockwise).
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.

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.
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.

Finally, to make things even more complicated, it is likely that the roles of the lower body muscles may differ according to if: (1) the jump is maximal or sub-maximal, (2) long-term training has occurred, and (3) the individual has a “hip-dominant” or a “knee-dominant” technique. Indeed, the vertical jump is more dependent upon the hip extensors in maximal jumps, compared to in sub-maximal ones. And after long-term jumping training, the increase in the amount of work done in the jump by the hip extensors is related to the increase in height, while the increase in the amount of work done by the knee extensors is not.


A more accurate method would be to use a Jump Tester (like these here.) The problem with these, obviously, is that they are way too expensive. In fact, the only scenario in which I recommend using one of these is if you’re a coach, trainer, or athletic director who is purchasing it to test a large number of athletes over time and who needs as accurate of a number as possible for scouting purposes.
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.
Increase your vertical leap. You will need the lifting power of your legs to get you in the air and up to the basket. Building a regimen of leg workouts that will increase the fast-twitch strength and the flexibility of your leg muscles can help you add inches to your vertical leap, getting you that much closer to the rim.[2] A good regimen to get started with might include:

Among the hundreds of lessons I learned during my youngest child’s first year of life was this: If you earnestly pursue dunking after your athletic peak years of 18 to 30, give or take, it can be done. You can enjoy what it feels like to dunk. You can even feel it more purely than I did, maybe without needing a lob from a friend, and hopefully without all the hand damage. But you should expect a long, frustrating, demeaning war of attrition that pits mind, body, spirit against the most oppressive, unrelenting opponent of them all: gravity. The sun rises and sets, the tides creep in and out—even taxes and death seem negotiable nowadays—but gravity remains constant, forever pounding our shoulders, stooping us shorter as we grow gray, never letting up—no matter what NASA tweets.
If you can jump high enough to dunk, but you’re having a hard time going up with the basketball in one hand, the solution is to start small and work your way up. A smaller ball such as a soft golf ball or tennis ball is a great starting point. From there, move slowly to a mini-basketball. It will provide more of a challenge but still be easy to palm as you go up. Once you can dunk the mini ball, try moving on to a volleyball until finally a regulation basketball.
For improving vertical jumping ability, the back squat and jump squat have been used for many years with great success. Depending on the exact force-velocity profile of the athlete, either back squats or jump squats should be effective for improving vertical jump height. Even so, exercises that shift the load towards the center of mass of the body, such as hex bar deadlifts and weighted vest jumps could be superior.

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.
The record for the most WNBA dunks belongs to Brittney Griner. As a high school senior, she dunked 52 times in 32 games and set a single-game record of seven dunks.[47] As a standout at Baylor University, Griner became the seventh player to dunk during a women's college basketball game[48] and the second woman to dunk twice in a single college game.[49] In her WNBA debut on May 27, 2013, Griner dunked twice, and as of 2014, has five WNBA dunks, including the first in a playoff game (August 25, 2014).

El libro La doctrina del shock propone que las políticas económicas del Premio Nobel Milton Friedman y de la Escuela de Economía de Chicago han alcanzado importancia en países con modelos de libre mercado no porque fuesen populares, sino a través de impactos en la psicología social a partir de desastres o contingencias, provocando que, ante la conmoción y confusión, se puedan hacer reformas impopulares. Se supone que algunas de estas perturbaciones, como la Guerra de las Malvinas, el 11 de septiembre, el Tsunami de 2004 en Indonesia, o la crisis del huracán Katrina pudieron haber sido aprovechadas con la intención de forzar la aprobación de una serie de reformas.

Barry, who retired from the NBA in 2009, recalled that a few days before our sit-down he “drove out to the Clippers’ practice facility, wearing sneakers and board shorts, just to get my basketball fix in. Between games I pick up a ball and start shooting. In the back of my mind I’m thinking, You’re 42, man; can you still? So I get a rebound, do a little power dribble in the paint and, sure enough, throw it down. I put the ball down and walked out. I can still do that. That’s good.”
I just got the bike on Friday and used it twice over the weekend so this isn't a long-term review but my initial impression is highly favorable. I am a "serious" cyclist, which is not to say I'm a professional or anything like that but I log a lot of miles on my road bike and use high-end equipment. I've always hated hooking a bike up to an indoor trainer and I've avoided that type of training for many years. I finally went in on a spinning bike and I am very impressed with the results.

A more accurate method would be to use a Jump Tester (like these here.) The problem with these, obviously, is that they are way too expensive.

I sent a video of my soccer ball dunk to Todd, the #fivefivedunker, who informed me that I was leading with the wrong leg. I’d been taking my last big step with my left foot, which, as a righty, was like swinging a bat cross-handed. A few days later I encountered a blogger and 43-year-old dunker named Andy Nicholson who showed me, among many other things, that I wasn’t the only one with blood on my hands. Nicholson was one of dozens of YouTubers, young and old (mostly young), who were documenting online their attempts to dunk. “Yes!” he yelled over the phone when I told him about the open sores on my fingers. “Those are badges of honor!”
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.
I'm 33 yrs old, turning 34 in a month. I stand 5'7" and weigh 155 lbs. I used to touch the rim with both hands but now I can only touch the back board... I almost came close to dunking, but that was when I was 22 years old. I still dream of dunking one in...but I think the exercises that I used to do...don't seem to work anymore... Is it still possible for me to dunk even at this age?

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.
