When I started to work on the video tool that measures vertical jump, I had to dust off my old textbooks to learn about the relationship between hang time and jump height. And to my surprise, it turned out that the vertical jump is a great (and interesting!) example of the laws of physics at work. You can really learn about the relationship between velocity, acceleration, forces and hang time. Definitely more interesting than the average example of your physics textbook!
Janik was available by text whenever I needed him, like my very own dunk training app. The important thing, he said, was to work out hard and smart. When my knees or back were sore, he advised lowering the weight for a few sessions and eliminating depth jumps. "Listen to your body," he told me. And I did: I took a day off here or there if I needed it; I added more weight when I felt good. When, after five weeks, I started to worry that I wasn’t going to dunk again, he kept me motivated. "Leg strength is the key. Squat deep. Ass to grass," he told me, unsympathetic to the known fact that squats are fucking terrible.
My warmup on March 29, following a day of recovery, left me feeling hoppier than I’d expected, and not nearly as achy. After 10 devastating near misses, and several others that weren’t as close, Jeff lofted the best lob I would see during this journey. I leaped, controlled it with one hand and—boodaloomp—in and out. I could have wept. “You got this!” Jeff implored. “You know you got this!”
In 2004, as a high school senior, Candace Parker was invited to participate in the McDonald's All-American Game and accompanying festivities where she competed in and won the slam dunk contest.[51] In subsequent years other women have entered the contest; though Kelley Cain, Krystal Thomas, and Maya Moore were denied entry into the same contest in 2007.[52] Brittney Griner intended to participate in the 2009 McDonald's Dunk Contest but was unable to attend the event due to the attendance policy of her high school.[53] Breanna Stewart, at 6'3" (191 cm), Alexis Prince (6'2"; 188 cm), and Brittney Sykes (5'9"; 175 cm) competed in the 2012 contest; Prince and Sykes failed to complete their dunks, while Stewart landed two in the first round but missed her second two attempts in the final round.[54][55]
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.


Bought this as a training aid for my track team and so far no complaints it really does what i need it to do. I would recommend you come up with some drills when you buy this because if you improperly use it could injure the athlete you can not wing it with this. i like to you use it for warms ups or for specific strength training for my better athletes.
This list of movements was compiled by a pair of trainers who know a thing or two about making athletes more explosive: Jason Benguche, assistant strength and conditioning coach for the Carolina Panthers (@movement_mogul on Instagram), works one-one-one during the season with the NFL’s most explosive quarterback, Cam Newton. And Firdose Khan (@dose_9), head trainer at Nine Innovations athlete training facility in Houston, has worked with such athletes as former NBA MVP Derrick Rose and NFLers Arian Foster, Braxton Miller, and Brian Cushing.

An impressive vertical jump is the ultimate standard of lower-body power and explosiveness—an attribute that pays as many dividends in high-impact sports like basketball, football, and soccer as it gets you wide-eyed looks in the gym. Increase your hops, and chances are you’ll also be able to run faster, lift more weight, and maybe even throw down a dunk at your next pickup basketball game.
Before and after every workout, stretch your legs. This can lead to increase flexibility which loosens your muscles and allows them to perform better with a greater range of motion. In other words, they are strong and function better. Be sure to include dynamic stretches into your warm-up to get your joints moving and static stretches into your cool down after the workout.
Less helpful was my early realization that I was a two-hand dunker, in light of my inability to palm a basketball on the move. It’s common knowledge among dunkers that throwing down with two hands is typically harder than with one; the former requires a higher vertical leap. So as I flailed haplessly at the rim last spring with one hand, I felt not just discouragement but also fear. Fear that I would miss big chunks of my kids’ ninth, sixth, and first years on earth just so I could come up embarrassingly short on a senseless goal that my wife and I would later estimate consumed 15 to 20 hours a week, on top of my normal work hours. And fear that I had shared this idea with my editors way too soon.

The baseline dunk is an approach-modifier of any dunk type in which the player approaches the basket along the court-boundary (baseline) which runs parallel with the backboard. In the game setting, the dunk often comes as the result of a pass, creating an assist opportunity for a teammate. In the contest, the baseline approach may be used as a means of convenience, facilitating a particular dunk type (e.g., passes bounced off the side of the backboard or its padding) or to increase the difficulty of a dunk type in hopes of meriting higher scores.
My early efforts were clumsy. Jumping willy-nilly as high as I could, with no regard for technique, I occasionally felt my finger graze the underside of the rim. Most times I did not. What I did feel early on was a firm self-awareness­ that I was a two-foot jumper (like Spud Webb, Dominique Wilkins, Vince Carter and myriad NBA Slam Dunk champions with whom I have nothing else in common athletically) as opposed to a one-foot jumper (see: Julius Erving, Clyde Drexler, Michael Jordan). This meant that my best shot at dunking would be to elevate like an outside hitter in volleyball—that is, by stepping forward with one foot, quickly planting my trailing foot next to it and then propelling myself upward off both.
Go between the legs. While he wasn't the first player to complete it, Vince Carter wowed crowds at the 2000 NBA dunk contest by passing the ball under one leg while in the air and slamming it with authority. It didn't hurt that his forehead was almost touching the rim. If you've worked your ups to that height, try passing it under one leg and dunking it.
“No, not Dad,” Oliver said in the brick tract home where he grew up. “He was an older dad, like you, and his family was the focus of his life. The only time he wasn’t home with us kids was when he went out on the road for Phillips Petroleum, buying and selling leases in western Kansas and Oklahoma. When he got back he’d say, ‘All I wanted to do was come home.’ ”
Try calf raises for an easy way to exercise your calves. In a standing position, push on the balls of your feet while raising your heels so that you’re standing on your toes. Hold this position for 1-3 seconds, then slowly lower yourself back down to starting position. Do 10 reps, or as many as you can, and do as many sets as needed to complete 30 reps overall.[4]

Increase your vertical leap. You will need the lifting power of your legs to get you in the air and up to the basket. Building a regimen of leg workouts that will increase the fast-twitch strength and the flexibility of your leg muscles can help you add inches to your vertical leap, getting you that much closer to the rim.[2] A good regimen to get started with might include:


Jumpsoles v5.0. The Jumpsoles are vertical jump shoes that fit onto your existing shoe. They are plyometric platforms that attach to your shoes and focuses your body weight onto your calves and train you to spring off the balls of your feet. By doing the special plyometric exercises in the video you develop fast twitch muscle fibers in your legs for explosive leaping improvement. Jumpsoles have been around for over 20 years and many players have increased their vertical jump with them. See real Jumpsoles reviews here.
El economista Tyler Cowen, quien llamó a la retórica de Klein "ridícula" y el libro un "verdadero desastre económico", dice que el libro contiene "una serie de proposiciones inventadas, tales como la idea de que Margaret Thatcher creó la crisis de las Islas Malvinas para aplastar a los sindicatos, y endosarle el capitalismo sin restricciones a un público británico poco dispuesto."18​
Some days I would be doing leg exercises — you want to give yourself a 48-hour break between heavy lifting involving any given part of your body, to give yourself time to recover. Some days, I’d go out to the track and do a track workout like sprints. I was avoiding doing long-distance running, because I didn’t want to develop slow-twitch muscles. I wanted to concentrate on fast-twitch muscles. And then for fun, on the weekends, I would play soccer or pickup basketball. I was becoming a better athlete because of this. Not only was I faster and stronger, but I was also more confident, in terms of just the run of play in any of these team sports, because I was more athletic than I had been.
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.
