Circulatory shock is a life-threatening condition that is associated with high mortality.1,2 The administration of fluids, which is the first-line therapeutic strategy, is often insufficient to stabilize the patient's condition, and adrenergic agents are frequently required to correct hypotension. Among these agents, dopamine and norepinephrine are used most frequently.3 Both of these agents influence alpha-adrenergic and beta-adrenergic receptors, but to different degrees. Alpha-adrenergic effects increase vascular tone but may decrease cardiac output and regional blood flow, especially in cutaneous, splanchnic, and renal beds. Beta-adrenergic effects help to maintain blood flow through inotropic and chronotropic effects and to increase splanchnic perfusion. This beta-adrenergic stimulation can have unwanted consequences as well, including increased cellular metabolism and immunosuppressive effects. Dopamine also stimulates dopaminergic receptors, resulting in a proportionately greater increase in splanchnic and renal perfusion, and it may facilitate resolution of lung edema.4 However, dopaminergic stimulation can have harmful immunologic effects by altering hypothalamo–pituitary function, resulting in a marked decrease in prolactin and growth hormone levels. 5

Stand on the bottom step of a flight of stairs holding the railing on either side. Place the balls of your feet on the stair with your heels hanging off the edge. Slowly raise your heels as high as you can, and hold for two seconds. Slowly lower your heels below your toe level, and hold for two seconds. Repeat calf raises exercise 20 times for three sets with a 1-minute break between each set.


The between-the-legs dunk was popularized by Isaiah Rider in the 1994 NBA slam dunk contest,[12] so much so that the dunk is often colloquially referred to as a "Rider dunk" — notwithstanding Orlando Woolridge's own such dunk in the NBA contest a decade earlier.[13] Since then, the under-the-leg has been attempted in the NBA contest by a number of participants, and has been a staple of other contests as well. Its difficulty — due to the required hand-eye coordination, flexibility, and hang-time — keeps it generally reserved for exhibitions and contests, not competitive games. Ricky Davis has managed to complete the dunk in an NBA game,[14] but both he[15] and Josh Smith[16] have botched at least one in-game attempt as well.


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).

This book is great. I was a little worried because I am a girl an wasn't sure if these excerises were gonna be too hard or effective. But Jack Cascio shows great exercises and explains the science behind vertical jump. He explain the exercises step by step and give you a website where to go if you need a visual. Very informative and great info. Will definitely help you increase you certain will you help you gain knowledge about it also.
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.

Parte 5, se introduce el complejo capitalismo de desastres en el que la autora describe cómo las empresas han aprendido a sacar provecho de tales desastres. Ella habla acerca de cómo el mismo personal pasa fácilmente de puestos relacionados con la seguridad y defensa de los organismos públicos de los Estados Unidos a puestos en empresas lucrativas.
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.
The player approaches the basket and leaps as they would for a generic dunk. Instead of simply dunking the ball with one or two hands, the player allows their forearm(s) to pass through the basket, hooking their elbow pit on the rim before hanging for a short period of time. Although the dunk was introduced by Vince Carter in the 2000 NBA Slam Dunk contest, Kobe Bryant was filmed performing the dunk two years earlier at an exhibition in the Philippines.[22] Colloquially, the dunk has a variety of names including 'honey dip', 'cookie jar', and 'elbow hook'.
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 !
The primary end point of the trial was the rate of death at 28 days. Secondary end points were the rates of death in the ICU, in the hospital, at 6 months, and at 12 months; the duration of stay in the ICU; the number of days without need for organ support (i.e., vasopressors, ventilators, or renal-replacement therapy); the time to attainment of hemodynamic stability (i.e., time to reach a mean arterial pressure of 65 mm Hg)16; the changes in hemodynamic variables; and the use of dobutamine or other inotropic agents. Adverse events were categorized as arrhythmias (i.e., ventricular tachycardia, ventricular fibrillation, or atrial fibrillation), myocardial necrosis, skin necrosis, ischemia in limbs or distal extremities, or secondary infections.17

To perform two-foot dunks, jumpers bend their knees very deeply and spend a lot more time on the ground loading the jump. This increased time during takeoff is useful because it allows the athlete to transfer force into the ground thereby improving height. Using this approach makes it more difficult to transform speed into jump height making a fast approach far less useful than in one-foot jumping.


Sets/Reps: For general strength and lower-body development, Benguche recommends 3–6 sets of 3–8 reps with moderate loading—70%–85% of your one-rep max (1RM). For developing more speed and power, he recommends lighter loads (55%–70% of 1RM) for 3–6 sets of 2–5 reps. Squats performed with light weights but done so explosively that your feet leave the floor when you come up are called jump squats (see “Progressions” below).

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.[1] It is considered a type of field goal; if successful, it is worth two points. Such a shot was known as a "dunk shot"[1] until the term "slam dunk" was coined by former Los Angeles Lakers announcer Chick Hearn.[2]
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.
Toe Raises – stand with your feet shoulder width apart, typically on stairs or any sort of ground you can stand on that allows your heel to dip down. Then raise up on the tips of your toes. Continue this process until your complete your reps. Don’t rock up and down – or go to fast. For the exercise to work, you have to use correct form and go at a steady pace.
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.
Smaller observational studies have suggested that treatment with dopamine may be detrimental to patients with septic shock.3,9,10 However, Póvoa et al. reported a lower rate of death among patients treated with dopamine than among those treated with norepinephrine.25 In our study, which included more than 1000 patients with septic shock, there was no significant difference in the outcome between patients treated with dopamine and those treated with norepinephrine.
Perhaps the most popular obstruction-modified dunk is the Dubble-Up. Aptly eponymous of the its pioneer—T-Dub, an American dunker hailing from Minnesota—the Dubble-Up starts with a person standing before the basket, holding the ball above their head. The dunker approaches and leaps as though their groin would soar above just above the head and their legs around the stationary person. Just prior to clearing the person, the dunker will assume control of the ball with one or both hands, guide it under a raised leg, transferring it to the appropriate hand, clearing the ball-holder, raising the ball above the horizontal plane of the rim, and finally guiding it downward through the basket. While the Dubble-Up mimics a between-the-legs dunk, Kenny Dobbs and Justin Darlington have both performed an under-both-legs variant.

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!”
At pickup the next night, buoyed by the previous day’s accomplishment, I found a regulation ball that had good grip, one I could palm, and in between games, when no one was looking, I dunked for the first time in eleven years. If some dunks are described as thunderous, this one could be best described as a gentle fart in the breeze. But a dunk’s a dunk—and I had dunked.
Four times a week, from April through October, I embarked on 90-minute explosive weightlifting sessions based on the years I’d spent working as a strength coach to club, college and professional volleyball players. Squats, squat jumps, deadlifts, lunges, box jumps, cleans, sprints. . . . Three or four days a week I visited one of my local blacktops, where I tried to dunk tennis balls on 10-foot rims or throw down basketballs and volleyballs on lower ones. By May 3—one month in—I could dunk a tennis ball on a 9' 10" rim. I considered this a better-than-good start, not realizing that compared to dunking a basketball, this tennis-ball jam was akin to a child scrawling the diagonal line that begins a capital A on his first day of learning the alphabet.

This phase begins with the athlete at the bottom of the jump, just as he begins exploding upwards towards the takeoff. The force-time graph shows that the athlete reaches peak forces shortly after reaching the lowest point of the jump. He then further accelerates until his feet leave the ground and there are no more ground reaction forces measurable.

Any athlete who wants to maximize the height of their vertical jump should look to reduce their non-functional body weight (body fat) as much as possible. Though it's generally not recommended for youth athletes to go on a calorie-restricted diet, they should look to make healthy food choices. A good starting point for this is 40% of calories from carbohydrates, 30% from protein, and 30% from fats.


Shocks work and the ride is much better but installing them is a pain. They don't come compressed and are hard to compress by hand. For a 2012 F250 I bolted the lower portion of the shock up then took a racket strap and hooked it around the top bolt collar. Racket it till its close to the hole then release the strap and knock it over in the hole. That was the way I did it. The first side took forever trying to muscle it in then I busted out the strap and had it on in 5min.........Good product but I wish it would have came compressed.

A common, low-tech plyometrics method is performing box jumps, where the athlete jumps repeatedly from the floor to the top of the box and back again. By concentrating on the mechanics of the jump, directing propulsion from the balls of the feet and thrusting with an explosive extension of the legs, the ability of the athlete to land lightly and immediately return to the floor enhances motor control over the movement.
