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.
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.
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 loading phase of a vertical jump should look very similar to a Romanian dDeadlift—the only difference is the arm position. In this position, the weight is on the toes. The knees and ankles are slightly bent, the chest is leaned forward and the arms are extended just past the hips. In this position, the athlete can generate the most amount of vertical power.
Not so long ago, I played the worst basketball game of my life. I missed layups, turned over the ball, allowed my opponent free reign to the hoop. It was dark. As I slumped on the sidelines after the game, I realized how far I’d fallen from my prime a decade ago. Back then, I could dunk; now, at 33, I could barely curl my fingers over the rim. My game had regressed to hovering around the arc jacking threes. The last time I dunked a basketball, Michael Jordan was a Washington Wizard and people still listened to Coldplay.
An important component of maximizing height in a vertical jump is attributed to the use of counter-movements of the legs and arm swings prior to take off, as both of these actions have been shown to significantly increase the body’s center of mass rise. The counter-movement of the legs, a quick bend of the knees which lowers the center of mass prior to springing upwards, has been shown to improve jump height by 12% compared to jumping without the counter-movement. This is attributed to the stretch shortening cycle of the leg muscles enabling the muscles to create more contractile energy. Furthermore, jump height can be increased another 10% by executing arm swings during the take off phase of the jump compared to if no arm swings are utilized. This involves lowering the arms distally and posteriorly during the leg counter-movements, and powerfully thrusting the arms up and over the head as the leg extension phase begins. As the arms complete the swinging movement they pull up on the lower body causing the lower musculature to contract more rapidly, hence aiding in greater jump height. Despite these increases due to technical adjustments, it appears as if optimizing both the force producing and elastic properties of the musculotendinous system in the lower limbs is largely determined by genetics and partially mutable through resistance exercise training.
