procedure (see also variations below): the athlete stands side on to a wall and reaches up with the hand closest to the wall. Keeping the feet flat on the ground, the point of the fingertips is marked or recorded. This is called the standing reach height. The athlete then stands away from the wall, and leaps vertically as high as possible using both arms and legs to assist in projecting the body upwards. The jumping technique can or cannot use a countermovement (see vertical jump technique). Attempt to touch the wall at the highest point of the jump. The difference in distance between the standing reach height and the jump height is the score. The best of three attempts is recorded.
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'.
Dunking became a game again. After my closest misses I’d hop around and swear like a golfer whose playoff putt had lipped out. These outbursts were no longer harsh self-admonitions but celebrations of my progress, acknowledgements that I was getting tantalizingly close. I could feel my legs gaining in bounciness. I could feel my hips, quads and calves learning to fire simultaneously. My original lobber returned to the scene and suggested I try dunking in the morning instead of the evening, when the batteries in our old bodies are as low as the ones in our phones. I added this sage advice to the long list of micro­details “that help you steal inches,” as Todd had phrased it months earlier. “A quarter inch here, a half inch there.”

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

For taxonomic purposes it is an important distinction, but the modifiers discussed below are often considered dunk types in common parlance. This misconception is perhaps attributable to the modifier being the most salient component of the dunk from the perspective of the observer. However, each dunk modifier requires a dunk type to be a successful dunk—albeit the most-basic dunk type.
One morning a week later, the gym at the Y was empty. I picked up the same mini-ball and unsuccessfully tried to throw it down. I found the more relad I was, the higher I could jump. So I loosened my shoulders, took a depth breath, and approached the rim. I held the ball for a beat longer this time, and easily popped it over the rim. It felt incredible. I did it a few more times, each easier than the last, pulling down on the rim with unnecessary force for maximum satisfaction. But as exhilarating as it was to dunk again, I was only using a mini-ball—I hadn’t completely reached my goal.

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.
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.
Some players thinking jumping off two feet to be more comfortable, but it’s different for every player. Take time while you’re practice your jump to find what’s the most comfortable for you. As you’re learning the right way to jump, comfort is crucial because you don’t want to hurt yourself making a move that feels awkward. You want to be comfortable taking off and landing - and that can be done a number of different ways.
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.
Perform the routine every second day to give your body a days rest in-between workouts. This means that on week one you’ll be training 4 times a week, week two you’ll be training 3 times per week, and on week three you’ll be training 4 times per week. That ends up being 11 workouts per phase for a total of 33 workouts in the program. Also, during this program you will be taking one week off between each phase to let your body completely recover. You need to give your muscles time to fully repair in order to grow stronger and more explosive.
