Shock absorbers are basically oil pumps. A piston is attached to the end of the piston rod and works against hydraulic fluid in the pressure tube. As the suspension travels up and down, the hydraulic fluid is forced through tiny holes, called orifices, inside the piston. However, these orifices let only a small amount of fluid through the piston. This slows down the piston, which in turn slows down spring and suspension movement.
Dunking was banned in the NCAA from 1967 to 1976. Many people have attributed this to the dominance of the then-college phenomenon Lew Alcindor (now known as Kareem Abdul-Jabbar); the no-dunking rule is sometimes referred to as the "Lew Alcindor rule."[3][4] Many others have also attributed the ban as having racial motivations, as at the time most of the prominent dunkers in college basketball were African-American, and the ban took place less than a year after a Texas Western team with an all-black starting lineup beat an all-white Kentucky team to win the national championship.[5] Under head coach Guy Lewis, Houston (with Elvin Hayes) made considerable use of the "stuff" shot on their way to the Final Four in 1967.[6]
Plyometrics is the best known of the jumping development exercise programs. Plyometrics training emphasizes speed and explosive movement, and a plyometrics program will typically consist of a series of bounding, hopping, and jumping drills. The object of a plyometrics program is to perform the exercises at maximum intensity. For this reason, plyometrics training must be approached with caution, and the athlete must progress slowly from one level to the next to reduce the risk of injury. Proper rest intervals must also be incorporated in to plyometrics training, as the exercises are intended to place significant stress on the target muscle groups.
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:

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]
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.
Where it (relatively) falters is in the oft gratuitous sexual content, occasionally drawn out beyond all reason. This holds particularly true of Million's trawl through the mind's red light district full of tempting whores like Orientals Kia and Tricia Yen and Caressa Savage, abusing herself at length with a scary looking dildo. At best, the sex is still positively riveting though with sweet Shayla subjugated to a pair of fearsome gargoyles (T.T. Boy and Vince Voyeur in amazing body make-up) and a group of pony girls - remember them ? - at film's climax.
At the onset of the jump, the ball is controlled by either one or both hands and once in the air is typically brought to chest level. The player will then quickly thrust the ball downwards and fully extend their arms, bringing the ball below the waist. Finally the ball is brought above the head and dunked with one or both hands; and the double clutch appears as one fluid motion. As a demonstration of athletic prowess, the ball may be held in the below-the-waist position for milliseconds longer, thus showcasing the player's hang time (jumping ability).
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 !
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.
In 2004, as a high school senior, Candace Parker was invited to participate in the McDonald's All-American Game and accompanying festivities where she competed in and won the slam dunk contest.[51] In subsequent years other women have entered the contest; though Kelley Cain, Krystal Thomas, and Maya Moore were denied entry into the same contest in 2007.[52] Brittney Griner intended to participate in the 2009 McDonald's Dunk Contest but was unable to attend the event due to the attendance policy of her high school.[53] Breanna Stewart, at 6'3" (191 cm), Alexis Prince (6'2"; 188 cm), and Brittney Sykes (5'9"; 175 cm) competed in the 2012 contest; Prince and Sykes failed to complete their dunks, while Stewart landed two in the first round but missed her second two attempts in the final round.[54][55]
Results: You need a 0 Inch vertical leap to touch the rim and 6 Inch leap to dunk considering that you have to jump about 6 inches over the rim to dunk. To accomplish that you have to leave the ground at a speed of 1.73 m/s vertically no matter how much you weigh. You need a force of 0 Newtons against the ground based on your weight to reach that speed assuming you bent your knees at an angle of 60 degrees. The force depends on how much you bent your knees. Check side bar.
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.

En la introducción del comienzo y final se muestra la historia de los últimos treinta años de la doctrina de choque económico que se ha aplicado alrededor del mundo, desde América del Sur en la década de los setenta hasta Nueva Orleans después del huracán Katrina. Klein introduce dos de sus temas principales. 1) En donde los profesionales de la doctrina de choque tienden a buscar una pizarra en blanco en el cual plasmar su ideal de crear economías de libre mercado, en el que inevitablemente requiere normalmente una violenta destrucción del orden económico preexistente. 2) Las similitudes entre la crisis económica y la doctrina original de la terapia de choque, una técnica psiquiátrica donde se aplicaron choques eléctricos a los pacientes con enfermedades mentales.

Want to increase your vertical jump for volleyball fast? The easy way is to use our vertical jump bands and wear them while you practice your spikes! Just put on the vertical jump bands during volleyball practice and you'll be training your vertical jump while you are also practicing your volleyball skills. This means you don't have to do extra vertical jump workouts to gain inches on your jumping ability.

Add some flair with a double-pump. Suggesting you're so high you could dunk it twice, in the double-pump dunk you bring the ball back down to chest level at the apex of your leap, then force it back up to slam it with authority. Some notable players, Tracy McGrady among them, would do this regularly while spinning in the air, doing a 360 dunk variation.


Hi, I’m Trevor Theismann and welcome back to the blog. Today we’ll be focusing on the vertical jump and looking for ways to jump higher and increase our vertical distance. We’ve demonstrated some vertical jump exercises on the blog in the past, but now let’s take a minute to talk about technique. Training your body to jump higher isn’t just a matter of reps and strength building. No matter how many box jumps you take on, your vertical distance isn’t likely to increase unless you’re building your jump reflex correctly.
My son asked me to get book to help improve his jump and was thrilled with the terrific tips it gave him. According to him, this book covers all the important basics and is a must-read for anyone looking to increase their athletic performance. The exercises are described in a clear, easy to follow manner...and now that I've read it as well I'm happy to say, I understand more of what my son is always going on about! ;)

This calculator tells you how much you need to jump to dunk a basketball. It will also give you an estimated force required to jump that high. The more you bent your knees the less force you'll need but you will need a lot of energy to take you from that position to the top. You can increase your vertical by training your legs to be able to deliver that much force.

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.
Writer Antonio Passolini (formerly "Johnny Jump-Up" in his Greg Dark days) borrows several elements of science fiction cyber classics such as BLADE RUNNER and STARGATE with an experimental project at the asylum ironically referred to as Mindgate. Employing intentionally impenetrable mumbo jumbo, Dr Hellstrom has created a doorway into the mind's realm as if it were a separate world running parallel to the physical one our bodies inhabit. The f/x when Mangrove and her henchmen (Decker again and Peter North) pass from one world to another are impressive, matching the big budget blockbuster original every step of the way.
My wife of 11 years, who isn’t a sports fan, knit her brow in confusion and nodded when I raised this idea for the first time. She wanted to care but could not muster the attention span, for she had given birth just three weeks earlier to our third daughter. I would be needed at home in the coming weeks—a reasonable expectation. Although I look back today with pride at how I balanced that responsibility with the time-consuming­ and far less important dedication to dunking, I knew at the time that I would miss a lot of family dinners, bath times and diaper changes so that I could ride my bike to the gym or to local playgrounds, with no guarantee that I would reach my goal, or even come close.
In the ABA, Charlie Hentz broke two backboards in the same game on November 6, 1970 resulting in the game being called.[43] In the NCAA, Jerome Lane shattered a backboard while playing for Pitt in a 1988 regular-season game against Providence, and Darvin Ham did the same while playing for Texas Tech in a tournament game against North Carolina in 1996.
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?
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]
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.
Scaling the back squat for beginner-level athletes generally entails sticking to lighter loads (even bodyweight only to start) while learning proper technique. Goblet squats with a kettlebell or dumbbell can be used to practice form, but keep in mind that goblets are an anterior (front-loaded) variation and won’t directly mimic the mechanics of the back squat.

Thank you very much for your sharing this information. I am excited to start working on your recommendations immediately. The information seems very clear and easy to follow. I like the available links, and the fact that I can use this product on my Kindle, although I am used my PC to view. The book is brief and not full of wordy marketing fluffy verbiage.

Hi I'm 14 turning 15 this year with a height of 5'8-5'9 and a standing reach of 7'5. Right now I am 190 pounds.I know I'm not physically fit. I can touch the net by just standing and jumping but not the rim. I really want to dunk since my friends can reach almost the rim while i can't even if I'm taller than them. Is it an impossible dream to dunk before my high school life ends? Also it will be nice to hear on how to lose weight. Since people tease me on how fat I am. But i am currently trying to lose weight and lost 14 pounds already. The only problem is my asthma which is making it hard for me to do physical activities.
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.
Step 3. Jump as high as you can while flinging your arms forward and overhead. When you leave your feet, only reach up with one arm; you’ll be able to reach a higher point this way versus reaching with both arms. Land softly with a slight knee bend, being careful not to let your knees cave inward. Drive them outward as you did when preparing to jump in the first place.
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".
Since the magnitude of the effect derived from observational studies can be misleading, we opted for a sequential trial design with two-sided alternatives20; the trial design called for analyses to be performed after inclusion of the first 50 and 100 patients, and then after inclusion of each additional 100 patients, and allowed for the discontinuation of the trial according to the following predefined boundaries: superiority of norepinephrine over dopamine, superiority of dopamine over norepinephrine, or no difference between the two. An independent statistician who is also a physician monitored the efficacy analyses and the adverse events; on October 6, 2007, after analysis of the outcome in the first 1600 patients showed that one of the three predefined boundaries had been crossed, the statistician advised that the trial be stopped.

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.
