The force-velocity profile can be described by three elements: (1) maximum strength, (2) maximum velocity, and (3) the slope of the force-velocity gradient, because this is what determines whether the balance between force and velocity is optimal at the desired speed for force production. Each of these factors is an independent predictor of vertical jump height.
Then you need to hold the chalk in your right hand, and then you need to jump from the same starting position (without a run-up). To do the jump, you’ll need to flex (bend) at the hip and knee joints and use your arms for momentum. At the top of the jump you’ll mark the wall (or chalk board) with the chalk. The score for the jump is the difference between the standing height and the jump height (in cm). The highest of three separate trials is recorded as your max score.
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!
“Put in the work. It’s muscle memory, first and foremost. Training­wise, people say, ‘You gotta do this, you gotta do that.’ I didn’t believe in that. I never worked on my legs in high school or middle school. I would just go through this routine over and over and over, visualizing that day when you dunk on the court. And then you live in that moment.”
I gave myself ten weeks to dunk again. It wasn’t going to be easy: I figured I’d need to add five or six inches to my vertical in order to dunk a regulation basketball. I was in half-decent shape, and at six-foot-three, I had height on my side. But I had a few things other than age working against me—namely feet that had flattened over the years to canoe paddles, and an ankle injury I’d never properly rehabbed.
Asher Price, a reporter at the Austin American-Statesman, spent a year of his life trying to find out and chronicled his quest to jam on a regulation hoop in the book The Year of the Dunk, which comes out in May. Price, who played coy about whether he was able to achieve his goal, spoke to Science of Us about what a rec leaguer would need to do to fly like a pro. (Spoiler: lots of squats and alley-oop attempts.)
The phrase "slam dunk" has entered popular usage in American English outside of its basketball meaning, to refer to a "sure thing": an action with a guaranteed outcome, or a similarly impressive achievement. This is related to the high probability of success for a slam dunk versus other types of shots. Additionally, to "be dunked on" is sometimes popularly used to indicate that a person has been easily embarrassed by another, in reference to the embarrassment associated with unsuccessfully trying to prevent an opponent from making a dunk. This ascension to popular usage is reminiscent of, for example, the way that the baseball-inspired phrases "step up to the plate" and "he hit it out of the park," or American football-inspired phrases such as "victory formation" or "hail Mary" have entered popular North American vernacular.
My four year old son has a whole bunch of books in this series. They are all AWESOME. My son really likes facts and history and these books are full of both. You don't read them like a story - rather, they are basically written as one fact after another with lots of exciting illustrations in between. I like that I can jump around from fact to fact or picture to picture, depending on my son's mood or attention span at that particular point in time. He has actually been absorbing many of the names and dates and facts and statistics. I love that these books make it fun for kids to learn! FIVE STARS!!!
The defining characteristic of the depth jump is that the jump is preceded with the strong eccentric (negative) muscle action caused by dropping down from a raised surface, as opposed to a standard box jump where you start on the floor. This makes the depth jump a true plyometric movement, where the muscles are stretched suddenly (by the impact of the landing), producing a powerful shortening of the muscle fibers.
Generally, a player can reach their highest when jumping off one foot and reaching up with one hand. For a player that is right-handed, the most common way is approaching from the left and jumping off the left foot with the ball in the right hand. Obviously, for a left-handed player, it’s coming from the right and jumping off the right with the ball in your left hand.
En “Diario de mi mente”, Ursula Meier dirige a Fanny Ardant y a Kacey Mottet Klein en la historia de un parricida que le confiesa a su profesora de literatura los motivos que le han llevado a matar a sus padres. En “Sirius”, ambientada en la Masacre del Orden del Templo Solar, Frédéric Mermoud fija su calmada mirada en el adoctrinamiento y el fatal desenlace de los miembros de una secta. En “Nombre: Mathieu”, Lionel Baier representa la capacidad de resiliencia de un joven, víctima de un criminal en los años 80. Finalmente, “El valle”, de Jean-Stéphane Bron, es la realística dramatización de la persecución de un coche en el que viaja un joven ladrón que intenta cruzar la frontera franco-suiza.

Even so, the back squat does differ in important ways from the vertical jump. Primarily, it involves a much greater trunk extension turning force, because of the barbell weight on the upper back, and this likely contributes to the more hip-dominant nature of the squat over the vertical jump. Secondly, it is often performed to a deeper depth, which can alter the relative contribution of each of the hip extensors to the movement, because of their different leverages at each joint angle. And thirdly, it only involves accelerating up to midway through the movement, while the vertical jump involves accelerating right up until take-off. This also affects the relative contribution of the hip extensors, as force production will be required in the jump even when the hip is nearly fully extended, while this is unnecessary in the squat.


Strength exercises include slow, controlled movements like squats, lunges, and weighted step-ups.  Power exercises require explosive, quick moves like those needed for plyometrics and power cleans. Plyometrics are explosive bounding, hopping and jumping drills that blend strength and speed. Finally, practicing maximum vertical jump will increase vertical jump.
