Important Update! – I have been receiving a few emails/comments on players tracking their jump during the course of their program. Please understand that what you are doing when completing a jump program is breaking down the muscle.  You aren’t going to see improvements mid-week because the muscle hasn’t healed properly. That’s why I suggest only checking how much you’ve improved at the end of each rest week. Rest is just as important as the routine. 
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.
After a one-week recovery period in January following Phase 1 of Jump Attack, Phase 2 brought an increase in intensity and time investment. This was the last stop before Phase 3, the wilderness where those attack depth jumps lived. (Attack depth jumps: Rest on your knees in front of a box; explode to your feet without using your hands; immediately jump onto the box; immediately jump as high as you can off the box, landing on the balls of your feet. Repeat. Many times. No blacking out allowed.) Phase 3 brought dramatic increases in both explosiveness and hip flexibility, two critical ingredients that I started to feel working in tandem. I emerged both confident and in dire need of another one-week recovery period, which I spent playing with our kids, watching dunk videos and mouthing the syllable Ow. Once healed, in early March, I returned to the rims with a friend whom I’d asked to toss lobs to me. There would be no more lifting. (After Jump Attack, what else could there possibly be?) From here on, I just jumped and recovered, jumped and recovered, attacking this tiny window of three or four weeks before my time away from the gym began to sap my strength. It would be over at that point, all over, whether I wanted it to be or not.
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.
For smaller guys much of the problem, and one I struggled with, is managing the ball. Like most guys my size I can palm a basketball if a grab it carefully, but realistically it isn’t going to happen without a little concentrated effort. Some of those big guys can make a basketball look like a volleyball, and they have no trouble getting hold of it and shoving it over the rim.

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.
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
To build strength in the legs that will be compatible with the speed developed through successful plyometrics drills, squat and lunge exercises are important components. Squats are performed with free weights, where the athlete uses a weighted bar to carry out the exercise. The additional weight will be supported by the body through the abdominal, lumbar (low back), and gluteal muscles, in addition to the legs. This form of exercise permits the strengthening of the legs in conjunction with enhancing the core strength of the body, essential to the balance necessary to have the several muscle groups involved in leaping work in harmony.

You will need to get at least that high to be able to snap the ball into the basket. If you're relatively short, then you have your work cut out for you. Developing a one-handed dunk requires less vertical ability than a two-handed dunk, and, for most players, jumping off of one foot from a running start makes it easier to jump high enough to dunk. There are many things that you can do to work on your vertical leap.
A strut is a major structural part of a suspension. It takes the place of the upper control arm and upper ball joint used in conventional suspensions. Because of its design, a strut is lighter and takes up less space than the shock absorbers in conventional suspension systems. Struts perform two main jobs. First, struts perform a damping function like shock absorbers. Internally, a strut is similar to a shock absorber. A piston is attached to the end of the piston rod and works against hydraulic fluid to control spring and suspension movement. Just like shock absorbers, the valving generates resistance to forces created by the up and down motion of the suspension. Also like shock absorbers, a strut is velocity sensitive, meaning that it is valved so that the amount of resistance can increase or decrease depending on how fast the suspension moves. 

Then you need to hold the chalk in your right hand, and then you need to jump from the same starting position (without a run-up). To do the jump, you’ll need to flex (bend) at the hip and knee joints and use your arms for momentum. At the top of the jump you’ll mark the wall (or chalk board) with the chalk. The score for the jump is the difference between the standing height and the jump height (in cm). The highest of three separate trials is recorded as your max score.
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]
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?

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.

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.
Then, in terms of exercises, you really need to get your whole body stronger. You need to improve your core, and obviously you need to improve your legs. So someone who is interested in jumping higher will find themselves doing a lot of squats. And I would suggest that if someone just started this, they could do a lot of squat exercises without even going to the gym or even bearing weight. You know, get up in their office cubicle and do ten squats. Three sets of ten reps of squats is a good workout.
Justifying these selfish, skewed priorities in my head as I stuffed a basketball into my backpack and pedaled away from our home would turn out to be one of the most formidable obstacles in my path. I must have whispered, What the f--- am I doing? as many times as I leaped toward one of the rusty rims scattered around the south Los Angeles beach community where we live. That latter number tallied somewhere around 5,000, according to my journal and 24-plus hours of video. Many of these jumps were attempted while wearing a weighted vest that pulled me downward, the same way that home pulled me sideways.
Vertical jump training and assisted vertical jump training (essentially with a negative load) can each increase vertical jump height through increases in countermovement depth, even while actually reducing peak force produced in the jump. This seems to happen because the tendon becomes more compliant after these types of training, which means they elongate more during the countermovement phase of the jump.
Dunking (or attempting to dunk) is a high-impact, highly intense activity that deserves a sufficient warm-up prior to a throw-down session. Just as you would for a lifting workout, start your warmup with a few minutes of low-intensity cardio, then progress to more dynamic movements—dynamic stretching/mobility drills as well as jumping. Before attempting your first dunk, take a couple dry runs with no ball where you’re touching or grabbing the rim at the top.
Single leg jumping with it's high impact forces and dependence on the elasticity of muscles and tendons works best for young athletes. With increasing age, the tendons and muscles lose their elasticity and springiness and the risk of injury gets higher and higher. That's why a lot of basketball players start to rely more and more on their two-foot jump as they get older. And the winner of the Olympic high jumping contest are almost always below 30.
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.
Resident Evil 2: DualShock Ver., known as Biohazard 2 DualShock Ver. (バイオハザード2:デュアルショックバージョン Baiohazādo Tsū: De~yuarushokkubājon?) in Japan, As the title suggests, is a second expanded version of Resident Evil 2 that became the base of other subsequent versions/ports of the game. The game was modified to incorporate support for the vibration function and analog control of the PlayStation DualShock controller.
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.

I think one way of thinking about it is, less parts of the body, and more the kind of muscle. You want to develop your quick-twitch, or fast-twitch, muscles, because at the end of the day, trying to dunk a basketball is an explosive activity. You’re not going for a long-distance run here. You’re doing three quick steps, a hard shove against the ground, and exploding upwards. So the question is how to turn yourself into basically a sprinter. You do a lot of jumping exercises where you’re doing box jumps, where you jump off one box and as soon as you hit the ground, you try to jump up onto another box. That sort of thing.
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".

We conducted this multicenter trial between December 19, 2003, and October 6, 2007, in eight centers in Belgium, Austria, and Spain. All patients 18 years of age or older in whom a vasopressor agent was required for the treatment of shock were included in the study. The patient was considered to be in shock if the mean arterial pressure was less than 70 mm Hg or the systolic blood pressure was less than 100 mm Hg despite the fact that an adequate amount of fluids (at least 1000 ml of crystalloids or 500 ml of colloids) had been administered (unless there was an elevation in the central venous pressure to >12 mm Hg or in pulmonary-artery occlusion pressure to >14 mm Hg) and if there were signs of tissue hypoperfusion (e.g., altered mental state, mottled skin, urine output of <0.5 ml per kilogram of body weight for 1 hour, or a serum lactate level of >2 mmol per liter). Patients were excluded if they were younger than 18 years of age; had already received a vasopressor agent (dopamine, norepinephrine, epinephrine, or phenylephrine) for more than 4 hours during the current episode of shock; had a serious arrhythmia, such as rapid atrial fibrillation (>160 beats per minute) or ventricular tachycardia; or had been declared brain-dead.
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.
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.
The way Arthur J. Daley and the other spectators at the Y felt when Fortenberry dunked—that’s how fans at the Oakland Arena felt on Feb. 12, 2000, when Vince Carter shoved his forearm into the rim and swung there by his elbow. What only the initiated noticed about Carter’s dunk was that if you froze him during his approach, he looked like Bob Beamon. Carter long-jumped some 12 feet, right foot leading the way, before landing for a nanosecond and blasting off into his two-footed ascent.

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 trial included 1679 patients, of whom 858 were assigned to dopamine and 821 to norepinephrine. The baseline characteristics of the groups were similar. There was no significant between-group difference in the rate of death at 28 days (52.5% in the dopamine group and 48.5% in the norepinephrine group; odds ratio with dopamine, 1.17; 95% confidence interval, 0.97 to 1.42; P=0.10). However, there were more arrhythmic events among the patients treated with dopamine than among those treated with norepinephrine (207 events [24.1%] vs. 102 events [12.4%], P<0.001). A subgroup analysis showed that dopamine, as compared with norepinephrine, was associated with an increased rate of death at 28 days among the 280 patients with cardiogenic shock but not among the 1044 patients with septic shock or the 263 with hypovolemic shock (P=0.03 for cardiogenic shock, P=0.19 for septic shock, and P=0.84 for hypovolemic shock, in Kaplan–Meier analyses).
Hi I'm 14 years old and 6 foot 4 I can dunk but not really good like I need more air so that I can dunk better and I'm trying to get my vertical jump up to 5 feet my vertical you probably will say that's crazy but it's possible a really love it that a 13 year old can dunk but I want to do something amazing and that is to be better that micheal Jordan and I will succeed thank you so much hope you see me in the NBA .

Similar to building explosive power by jumping over a stationary object, hurdles allow you to practice your leap. Space eight flights of hurdles two feet from each other and aim to jump over each like a pogo stick—basically, as high as you can. Repeat this for 10 repetitions: one flight of eight hurdles equals one repetition. Do this twice per week.
On the basis of the results of the SOAP study,3 which showed a rate of death of 43% among patients receiving dopamine and a rate of 36% among patients receiving norepinephrine, we estimated that with 765 patients in each group, the study would have 80% power to show a 15% relative difference in the rate of death at 28 days, at a two-sided alpha level of 0.05.
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.

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.
