Struts also perform a second job. Unlike shock absorbers, struts provide structural support for the vehicle suspension, support the spring, and hold the tire in an aligned position. Additionally, they bear much of the side load placed on the vehicle's suspension. As a result, struts affect riding comfort and handling as well as vehicle control, braking, steering, wheel alignment and wear on other suspension

At the competitive level (i.e., the NFL and NBA combines), vertical leap is measured using a “jump tester”—a tripod with a series of thin plastic sticks one inch apart. If you have access to this equipment, it’s your best bet for getting an accurate measurement. A cheaper, more feasible option is to do your jump next to a wall and mark the highest point you touch with a piece of chalk.

The rate of death at 28 days in this study was close to 50%, which is to be expected in a study with very few exclusion criteria and is similar to the rate in previous observational studies.3,9,21-24 Our trial was a pragmatic study that included all patients who were treated for shock states, and therefore, it has high external validity. The study design allowed for maximal exposure to the study drug, since we included patients who had received open-label vasopressors for a maximum of 4 hours before randomization and since during the 28-day study period, the study drug was withdrawn last when patients were weaned from vasopressor therapies and was resumed first if resumption of vasopressor therapy was necessary.
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.
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.
A great summary of what it takes to improve vertical jumping ability Joe. There is definitely an art and science to optimizing vertical jump height. I actually just completed a huge post on the topic of How To Jump Higher which your readers may find complements this post nicely. It is a long read (12000+ words) but for those of your readers who want to learn more about the art of jumping they may find it helpful. Keep up the great work!
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!
En “Diario de mi mente”, Ursula Meier dirige a Fanny Ardant y a Kacey Mottet Klein en la historia de un parricida que le confiesa a su profesora de literatura los motivos que le han llevado a matar a sus padres. En “Sirius”, ambientada en la Masacre del Orden del Templo Solar, Frédéric Mermoud fija su calmada mirada en el adoctrinamiento y el fatal desenlace de los miembros de una secta. En “Nombre: Mathieu”, Lionel Baier representa la capacidad de resiliencia de un joven, víctima de un criminal en los años 80. Finalmente, “El valle”, de Jean-Stéphane Bron, es la realística dramatización de la persecución de un coche en el que viaja un joven ladrón que intenta cruzar la frontera franco-suiza.
Independent 6'2" North American athlete Eric Bishop introduced a dunk entitled the 'Paint Job'. The title is in reference to the key on a basketball court, often known as 'paint' in common parlance.[36] Approaching along the baseline with a running dribble, Bishop jumped with one-foot at the border of the key, dunked with one-hand while gliding over the key and landed just beyond the border on the side opposite his take-off—a 16-foot flight.
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.

Exactly which muscles are most important for improving the vertical jump is still relatively unclear, and may differ between individuals. Clearly, the spinal erectors, hip extensors, quadriceps, and calf muscles are all involved in the jumping movement, and the hip extensors and quadriceps are likely the prime movers, but which of the hip extensors is the primary muscle is very unclear. Importantly, since force production is required right up until take-off, the lower body muscles must produce force from moderate through to short muscle lengths, which differs from the barbell back squat exercise.


Stand on your right leg and lift your left knee up as high as you can. Keeping your knee bent and your left leg out of the way, jump and land eight to ten times on your right leg. Focus on the landing. Your body should be ready to spring back up again the second you hit the ground. Try to jump higher with every repetition. Use your left hip and raised leg to build leverage.
Among patients with cardiogenic shock, the rate of death was significantly higher in the group treated with dopamine than in the group treated with norepinephrine, although one might expect that cardiac output would be better maintained with dopamine26-28 than with norepinephrine. The exact cause of the increased mortality cannot be determined, but the early difference in the rate of death suggests that the higher heart rate with dopamine may have contributed to the occurrence of ischemic events. Whatever the mechanism may be, these data strongly challenge the current American College of Cardiology–American Heart Association guidelines, which recommend dopamine as the first-choice agent to increase arterial pressure among patients who have hypotension as a result of an acute myocardial infarction.7
This book is just a glimpse of some of the great workouts, and outcomes of the workouts he has to offer. Right now I am in the middle of his Twice The Speed workout AND Vertical Jump Cure (found in the back of the book), and it is defiantly something you need to checkout if you like what this book offers. But not only does he have vertical jump workouts or speed workouts but he has nutrition guides, flexibility cure, and many other bonuses.
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).
The two-hand backscratcher finish can exert tremendous force on the basket. In 1979, Darryl Dawkins twice shattered NBA backboards with tomahawk dunks leading to a quickly-enacted rule making it an offence to break the backboard.[citation needed] Technology has evolved to adapt to the increased strength and weight of players to withstand the force of such dunks, such as the breakaway rim (introduced to the NBA in 1981) changes to the material used for the backboards, and strengthening of the goal standards themselves.
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.
Overall, 309 patients (18.4%) had an arrhythmia; the most common type of arrhythmia was atrial fibrillation, which occurred in 266 patients (86.1%). More patients had an arrhythmia, especially atrial fibrillation, in the dopamine group than in the norepinephrine group (Table 3). The study drug was discontinued in 65 patients owing to severe arrhythmias — 52 patients (6.1%) in the dopamine group and 13 patients (1.6%) in the norepinephrine group (P<0.001). These patients were included in the intention-to-treat analysis. There were no significant differences between the groups in the incidences of other adverse events.
“There’s something about dunking a basketball that lures us in,” he said, reflecting on his first jam, during lunch period his sophomore year at De La Salle High in Concord, Calif., back when his driver’s license read 5' 11", 112 pounds. “It stokes the imagination. It’s something you always dream of doing. I have a friend whose father, at age 50, is trying to dunk.”
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]

Discussed in this module are activities which when applied, modify a given dunk type. Modifier-activities occur prior to leaping or while airborne. Modifiers performed prior to leaping pertain to the manner of approach (e.g., locomotion or standstill), angle of approach (e.g., from the baseline), distance of leap from the basket, the addition of a pass (e.g., alley-oop), or some combination thereof. Modifiers performed while airborne pertain to bodily rotation (e.g., 360°), obstruction of own vision (e.g., arm-over-the-eyes), other bodily movements superfluous of dunk type (e.g., voluntary kicking of the legs), or some combination thereof. Dunk types can also be modified with obstructions (e.g., leaping over a car or person) which influence activities both prior to leaping and while airborne.
Dunking a basketball is a lot of fun, and for most of us that is really the only reason to do it. Especially when you are a shorter player, it is cool to see the looks on the big guys’ faces when you do something you really ought not to be able to do. But let’s be realistic here: If you want to be a good basketball player there are many, many skills that are more important to spend time on. For most of us, the ability to dunk is an insignificant part of our game.

My four year old son has a whole bunch of books in this series. They are all AWESOME. My son really likes facts and history and these books are full of both. You don't read them like a story - rather, they are basically written as one fact after another with lots of exciting illustrations in between. I like that I can jump around from fact to fact or picture to picture, depending on my son's mood or attention span at that particular point in time. He has actually been absorbing many of the names and dates and facts and statistics. I love that these books make it fun for kids to learn! FIVE STARS!!!
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.
I think it’s the sort of thing that a lot of kids probably fantasize about, me included. Just like you might want to become an astronaut or something like that. I was always one of the tallest kids in my class, but I never really tried to dunk. And so as an adult, you start wondering a little bit about what sorts of things you left on the table, that you never really tried your hand at. And I got it into my head that I’d pick up this childhood fantasy of mine and see if I could dunk.

I just turned 14 year old 5''10-5''11 8th grade 160-70 poundsand 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 ive dunked maybe over 10 times with one hand it effortless to touch rim with both feet and easier with one but i''''''''m also wondering how to take of when i dunk because i stutter step and i want to get my explosiveness up. Can anyone help me?
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.
Bodyweight squats are a great way to practice your vertical jump because your squat stance mimics the lowest crouch position of your vertical jump. Incorporate these into your routine twice every week, increasing the number or sets and reps as you improve. After you become comfortable with regular squats, consider adding jump squats to your routine.

Keep that in mind, and progress slowly. A mini basketball is a little more challenging than a tennis ball, but it's easy to palm and that helps. See if you can get high enough to get your hand over the rim--almost up to your wrist--so you can stuff the mini ball. If you can't throw it down with a little authority, a bigger basketball won't be any easier.
Hi im Deontay i been trying 2 dunk ever since 7th grade and i know i been improveing since 7th grade i could touch the bottom of the backboard and i guest i was 5'6 or 5'7 at the end of the 8th grade i started exercising by having a 150 pound bag of cement on my shoulders and started squats and i try 2 15 wit a extra 5 at ever exercise i do but i still c very little effects so when went 2 my last day of school i could touch rim easily but the rim was about 8 foot and i was 5'9 now im a freshmen at my high school and i grip 10 foot rim wit my fingers not wit my hands but wit my fingers and im at 5'10 and im only 15 and i think my growing sprout is kicking in but anyway i want 2 know how can i get the ball over the rim and pound it in like d.rose king james and blake griffin i could grip the ball all i need 2 know is how 2 jump high enough 2 have that ball above the rim and pound it in will u please help

I learned that insects are fucking awesome. There was an insect in particular that I was interested in called the froghopper, or spittlebug, that is basically one of the world’s top jumpers. It’s a survival mechanism. It can jump far, far higher than we can as a function of its weight, basically. So I learned that humans are quite modest in the jumping scheme of things.

During the 1940s and 1950s, 7-foot center and Olympic gold medalist Bob Kurland was dunking regularly during games.[7] Yet defenders viewed the execution of a slam dunk as a personal affront that deserved retribution; thus defenders often intimidated offensive players and thwarted the move. Satch Sanders, a career Boston Celtic from 1960 to 1973, said:


Less helpful was my early realization that I was a two-hand dunker, in light of my inability to palm a basketball on the move. It’s common knowledge among dunkers that throwing down with two hands is typically harder than with one; the former requires a higher vertical leap. So as I flailed haplessly at the rim last spring with one hand, I felt not just discouragement but also fear. Fear that I would miss big chunks of my kids’ ninth, sixth, and first years on earth just so I could come up embarrassingly short on a senseless goal that my wife and I would later estimate consumed 15 to 20 hours a week, on top of my normal work hours. And fear that I had shared this idea with my editors way too soon.
i am 6 foot 2 inches tall, i am in the 8th grade, and i am 13 years old going on 14 in september. I discovered on May 15th that I could hang on the rim at my school with two hands by jogging about 3 steps very very slowly and jumping off both of my feet. I have dunked about 3 times before, but the last couple times I tried, I got "hung" and sent backwards but I managed to keep balance on the way down due to my height. What is my problem? Also after I attempt to dunk about 4 times in a day my shin begins to hurt. Why does this keep happening?
If the patient was already being treated with a vasopressor at baseline, that agent was replaced as soon as possible with the trial-drug solution. If the patient was already receiving dopamine and this agent could not be discontinued after introduction of the trial-drug solution, the dopamine was replaced with an open-label norepinephrine infusion. Open-label dopamine was not allowed at any time. Epinephrine and vasopressin were used only as rescue therapy. Inotropic agents could be used, if needed, to increase cardiac output.
A second, more efficient and correct method is to use an infrared laser placed at ground level. When an athlete jumps and breaks the plane of the laser with his/her hand, the height at which this occurs is measured. Devices based on United States Patent 5031903, "A vertical jump testing device comprising a plurality of vertically arranged measuring elements each pivotally mounted..." are also common. These devices are used at the highest levels of collegiate and professional performance testing. They are composed of several (roughly 70) 14-inch prongs placed 0.5 inches apart vertically. An athlete will then leap vertically (no running start or step) and make contact with the retractable prongs to mark their leaping ability. This device is used each year at the NFL scouting combine.
