We purchased this because of its safety evaluation and the high ratings. I did evaluate the negative reviews and was prepared for the issues reported, however; I found none of the comments in the negative reviews to be valid with our experience. First, for the people who complained about the assembly instructions- there are pictures....yes, the English is horrible, but there are pictures! Total assembly time, with one human, was 2 hours and 10 minutes. Assembly of the safety cage was the the most difficult part. Specifically, the foam comes in two sections, which makes it difficult to slide into the pocket. BUT, with a little patience it can be done. Second, to those who would rather purchase a unit from Walmart- this is a very fine product, with consumer quality pieces, they include gloves, spring tool, and a ladder- you don't get ... full review

A vital part of basketball training is improving your vertical leap. As an athlete, you should be incorporating exercises into your basketball drills and fitness training that focus on increasing muscle strength and leg speed. Simply put, you won’t turn into Vince Carter or Andre Iguodala overnight, but learning how to work the appropriate muscles on a daily basis will go a far way towards improving your overall 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.
Perform jump and reach exercises for a simple vertical jump workout. Start in a standing position with your arms above your head, your feet shoulder-width apart, and your knees and hips forward. Bring your arms down and back, while simultaneously lowering your hips and bending your knees. Then, swing your arms forward and jump as high as you can.[5]
Thus, dopamine and norepinephrine may have different effects on the kidney, the splanchnic region, and the pituitary axis, but the clinical implications of these differences are still uncertain. Consensus guidelines and expert recommendations suggest that either agent may be used as a first-choice vasopressor in patients with shock.6-8 However, observational studies have shown that the administration of dopamine may be associated with rates of death that are higher than those associated with the administration of norepinephrine.3,9,10 The Sepsis Occurrence in Acutely Ill Patients (SOAP) study,3 which involved 1058 patients who were in shock, showed that administration of dopamine was an independent risk factor for death in the intensive care unit (ICU). In a meta-analysis,11 only three randomized studies, with a total of just 62 patients, were identified that compared the effects of dopamine and norepinephrine in patients with septic shock. The lack of data from clinical trials in the face of growing observational evidence that norepinephrine may be associated with better outcomes called for a randomized, controlled trial. Our study was designed to evaluate whether the choice of norepinephrine over dopamine as the first-line vasopressor agent could reduce the rate of death among patients in shock.

A more accurate method would be to use a Jump Tester (like these here.) The problem with these, obviously, is that they are way too expensive. In fact, the only scenario in which I recommend using one of these is if you’re a coach, trainer, or athletic director who is purchasing it to test a large number of athletes over time and who needs as accurate of a number as possible for scouting purposes.
The vertical jump is defined as the highest point that the athlete can touch from a standing jump, less the height that the athlete can touch from a standing position. The measurement of the jump is flawed if the athlete is permitted to take one or more steps before jumping, as the athlete will convert some of the energy developed in the step taken into the force of propulsion that generates upward lift. Basketball has numerous legends and other urban myths concerning the seemingly superhuman leaping ability attributed to certain players; one such player, former University of Louisville star Darrell "Dr. Dunkenstein" Griffith, was reputed to possess a 42 in (1 m) vertical leap. It is likely that the average National Basketball Association player 6 ft 6 in (1.97 m) or shorter has a vertical leap of between 25 and 30 in (0.63 and 0.75 m); taller and heavier players will usually not be able to jump as high.
My son asked me to get book to help improve his jump and was thrilled with the terrific tips it gave him. According to him, this book covers all the important basics and is a must-read for anyone looking to increase their athletic performance. The exercises are described in a clear, easy to follow manner...and now that I've read it as well I'm happy to say, I understand more of what my son is always going on about! ;)

“There aren’t many people in the world who can [dunk], that’s why it has this allure, I guess,” Carter told me last fall, during his first training camp with the Grizzlies. “As far as trying to do it, there are so many ways people can go about it. The approach you’re taking is the right approach. When I was younger, that’s how I started. Tennis ball, to the point that it became easy. Then a volleyball. Then a girls’ ball. Finally I took—it was like a dodgeball. I dunked that and said, ‘You know what, I’m gonna try it.’ Next thing you know. . . .” He shrugged and smiled, the gray whiskers on his jaw sinking into a dimple.

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.[5] 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.[6][7]
