When I was growing up, basketball was big in my neighborhood. Everyone wanted to be able to dunk on a regulation 10-foot high basket and, thus, everyone focused on improving their vertical jump. The progression usually went a little something like this: touch the rim, grab the rim, hang on the rim, dunk with a volleyball and, finally, dunk with a basketball!
Still, by the late 1950s and early 1960s players such as Bill Russell and Wilt Chamberlain had incorporated the move into their offensive arsenal. The dunk became a fan-favorite, as offensive players began to aggressively intimidate defenders with the threat of vicious slams. Through the 1970s, the slam dunk was standard fare; David Thompson, Julius Erving, Darryl Dawkins, and others wowed crowds with high-flying moves.
Results: You need a 0 Inch vertical leap to touch the rim and 6 Inch leap to dunk considering that you have to jump about 6 inches over the rim to dunk. To accomplish that you have to leave the ground at a speed of 1.73 m/s vertically no matter how much you weigh. You need a force of 0 Newtons against the ground based on your weight to reach that speed assuming you bent your knees at an angle of 60 degrees. The force depends on how much you bent your knees. Check side bar.
Nothing generates more excitement in a basketball game than watching the creativity and athleticism of a player flying through the air and finishing with a slam dunk. It can single-handedly change the dynamic of the game and turn a regular player into a star. Although it helps to be tall or have a natural leaping ability, short people can develop the skills required to perform this amazing athletic feat with proper training and technique.
In the 1950s, Jim Pollard[28] and Wilt Chamberlain[29] had both dunked from the free throw line—15 feet from the basket. Chamberlain was able to dunk from the free-throw line without a running start, beginning his forward movement from within the top half of the free-throw circle.[29] This was the catalyst for the 1956 NCAA rule change which requires that a shooter maintain both feet behind the line during a free-throw attempt.[30]
For one-footed jumpers, the ball is generally transferred to the non-dominant hand just before or upon take-off; for two-footers, this transfer is often delayed for milliseconds as both hands control the ball to prevent dropping it. Once airborne, the dunker generally transfers the ball from non-dominant to dominant hand beneath a raised leg. Finally, the ball is brought upwards by the dominant hand and slammed through the rim.

The vertical jump is one of the most explosive physical movements executed in sport. In a number of sports, the higher the athlete is able to jump, the greater the prospects of success in that discipline. Basketball and volleyball are the two most prominent examples of sports where that correlation is plain. The jumping ability of an athlete is also an indicator of overall athletic ability, as there is a clear relationship between the ability to jump and the running speed that the athlete will develop over short distances. The National Football League, where prospective players are subjected to various physical tests, requires every player to be tested for both vertical leaps and 40-yd (37 m) sprints, irrespective of the position played.

This isn’t just some light-duty assistance exercise. The rear-foot elevated split squat (aka, Bulgarian split squat) is a legitimate movement for increasing pure glute and quad strength, which will in turn enhance power and vertical jumping performance. Even if you’re a two-foot jumper, focusing on one leg at a time like you do here will ensure that your dominant side isn’t compensating for your weaker leg during the movement.
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.
I scoured the Internet looking for guidance. There are dozens of sites promising a path to dunking, most of them coded at the dawn of the Web. It was daunting finding one that seemed legit. I ended up paying $67 for the Jump Manual, an online program offered by Jacob Heller, a trainer with a 42-inch vertical who counts NBA players among his clients, according to his website. Next, I ordered a pair of Strength Shoes. You’ll remember these if you’re a basketball player of a certain age—the ridiculous-looking training kicks popular in the ’90s, with a platform under the toe that places your bodyweight on the balls of your feet.
I followed the Jump Attack program to the letter, and my training in December, January and February looked and felt nothing like what had preceded it. I spent a month doing those nonsensical lunge holds (and squat holds, push-up holds, chin-up holds). I trusted those holds, and the tendon-testing leg workouts that lasted 2 ½ hours and left me tasting my own broken down muscle in my mouth. I trusted all of it because I was living in that moment, as Carter put it, when the hammering of Carter’s “muscle memory” into my body finally would bear fruit and I’d pitch the ball downward into a 10-foot hoop like a cafeteria customer dunking a roll in coffee.
In summary, although the rate of death did not differ significantly between the group of patients treated with dopamine and the group treated with norepinephrine, this study raises serious concerns about the safety of dopamine therapy, since dopamine, as compared with norepinephrine, was associated with more arrhythmias and with an increased rate of death in the subgroup of patients with cardiogenic shock.
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.
Because of the foam edges the fear of scraping your shins are gone so you can go harder but also because of the foam it is a little unstable when you jump to the 30" level. Instead of scraping my shin on the edge, the foam made the base a little unstable and the box kicked out. Luckily I was on a mat and not a hard floor. That is the only problem I saw with this box.

I thought I needed a rim. But what I found I really needed was a constellation of them. Having choices would prove useful because of the daytime obstacles, like elementary school PE students and our own kids’ after-school activities; and nighttime obstacles, like chain-link and padlocks, that I encountered. My training windows were narrow, so I learned to employ these outdoor rims strategically, the way the skateboarders in Dogtown and Z-Boys timed their secret sessions at drained swimming pools. The six or seven courts nearest our house featured rims that measured anywhere between 9 feet and 10' 2", a variance that allowed for different kinds of practice. The blisters and flayed calluses that soon bloodied my hands instructed me in the value of breakaway rims—the less rust the better. Because a Snap Back wasn’t always available, local residents may have spotted a sweaty forty­something man rubbing Vaseline on his hands in the corner of their child’s favorite playground last year. Sometimes he wore a weight vest that made him look like a jihadist. What I’m saying is, Thanks for not calling the cops.


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.

Struts also perform a second job. Unlike shock absorbers, struts provide structural support for the vehicle suspension, support the spring, and hold the tire in an aligned position. Additionally, they bear much of the side load placed on the vehicle's suspension. As a result, struts affect riding comfort and handling as well as vehicle control, braking, steering, wheel alignment and wear on other suspension
Tomorrow night, Brooklyn’s Barclays Center will host the annual NBA Slam Dunk Contest as part of the league’s All-Star Weekend. Dunking a basketball is generally reserved for seasoned athletes with the incredible vertical leap required to rise high enough to stuff a ball through a ten-foot rim. But what about the aging average Joes who grew up watching high-flying stars like Dominique Wilkins and Michael Jordan? Could they ever soar high enough to achieve the dream of every schoolyard baller in the country?
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.
Original shocks have a secocnd lower nut that prevents the shock rod from spinning when loosening or tightening the upper mounting nut. The Bilstein shocks are not equipped with the second nut and the shock rod turns while trying to tighten the upper mounting lock nut, making it impossible to tighten. I had to return the shocks and bought a different brand. Also, Bilstein's installation instructions are about the worst I have ever seen.

The amount of resistance a shock absorber develops depends on the speed of the suspension and the number and size of the orifices in the piston. All modern shock absorbers are velocity sensitive hydraulic damping devices - meaning the faster the suspension moves, the more resistance the shock absorber provides. Because of this feature, shock absorbers adjust to road conditions. As a result, shock absorbers reduce the rate of:
