The best way to increase your vertical leap seems to have become a sort of mystery these days; athletes wonder why the guy with really skinny legs can jump high, as well as the really muscular one with thick legs; they wonder why jumping off one leg is so much easier for some and more difficult for others; they wonder why so many workouts can yield so little results. Unknowing athletes are vulnerable to poor information supplied by the ease of publication on the internet. One kid had using a stairclimber as part of his jump training; another wanted to know how long it would be before he could dunk if he jumped rope every day; a 5'7" 13 year old girl wanted to dunk before high school; the list of the poorly informed goes on and on.

This mystery status of vertical jump training has led to a tendency to seek out new, revolutionary exercises and products; a mystery has to have a crazy answer, right? Thus, we see bizarre products like calf isolators, jumpsoles, and vertimax, and there are plenty of programs offering "revolutionary training" from "vertical jump experts. " There is also a gravitation towards less familiar, less traditional exercises. Many athletes learn about plyometrics and think that this different type of training which is specific to jumping must be the answer. It makes so much sense when a person first hears about fast and slow muscle contraction to only train with plyometric drills. Or there is the opposite opinion that squats and power lifts are the only thing needed for an exceptional vertical. Supporters of this opinion base it on the fact that world class olympic lifters often have verticals of 36 inches or more. My goal is to eliminate the confusion with simple, factual information.

The truth is that every athlete is different and will need to do training that fits his or her individual abilities. Many people are looking for one magical workout or even one exercise that will make them a superstar. That's not the way it works; things are a little more complicated than that. However, if you understand some things about the human body, it can be easy to create an intelligent and effective training plan. I began sharing what I've learned with whoever I can, because I am yet to find a complete, accurate source of information available for all. Everyone wants money for their "secret breakthrough formula. " Quality jump training is not a secret or a mystery, and I do not believe an athlete should have to pay $40 for a list of exercises and a chart of numbers. I hope to equip you with knowledge that will help you train intelligently for the rest of your life. Yes, I do have vertical jump training programs and exercise videos available for free, but I also want you to understand the science behind the training.

BASIC JUMP SCIENCE
The height a projectile flies is determined by the velocity of the center of mass as it leaves the ground. nba jerseys wholesale , The faster the initial upward velocity, the longer it will take for gravity to decelerate the projectile, and the higher it will travel. In the case of a human jumping, the projectile is the body, and the initial velocity is determined by the acceleration of the center of mass due to the force generated by the body. If you want to increase your vertical leap, the goal is to increase the force that your body can generate. Simple enough right? Just lift weights, and your muscles will grow; your legs will be stronger, and you'll jump higher. new hats , This is true to an extent, but you will likely discover at some point that jump training is not quite that easy.

The truth is that there are three different muscle, tendon, and nerve abilities that contribute to jumping, or most athletic movements for that matter. cheap nba jerseys , The first ability is maximum strength; this is the largest amount of force that a muscle can exert. This is the most familiar muscle quality and the most commonly trained. It is increased by common resistance training, which most people are familiar with. The back squat is an example of a resistance training exercise used in jump training. The second ability is rate of force development, more simply stated as explosiveness. Muscles cannot instantly exert their maximum force; it takes a little bit of time to activate all the muscle fibers. That time is small, just a fraction of a second, but it is still longer than the time it takes to jump, meaning that all the force a muscle can exert cannot be utilized in a jump. This is the reason for the gap between strength and jumping ability.

Consider this scenario. . . Let's say Timmy weighs 150 pounds and can exert a maximum of 500 pounds of force on his center of mass (COM) in the range of the jumping motion. As Timmy begins the jumping motion, his body is not generating that 500 pounds of force yet. 2/100 of a second after his muscles began to develop force, he is putting out 150 pounds, and his COM begins to accelerate upwards. At 1/10 of a second, his legs are putting out 215 pounds of force, and his COM is accelerating faster. By 2/10 of a second, the force on his COM has grown to 350 pounds, but unfortunately his legs and back are fully extended; he's done jumping. Timmy never got to use all his force. These force numbers are purely hypothetical, but 2/10 of a second is a common duration of the jumping motion. The maximum force an athlete's muscles can exert cannot be generated in that time. wholesale basketball jerseys , The goal for athletes is to train to increase the percentage of their maximum force that can be generated quickly enough for use in jumping and all athletic maneuvers.

This ability is improved by exercises that require fast muscle contraction; Olympic lifts (clean, snatch, jerk) and plyometric drills are the most common. Note though, that exercises that use fast movement do very little to increase the maximum strength of the muscle. Rather it is the ability of the nervous system to quickly stimulate muscle fibers that is the focus of this training. The third ability that contributes to jumping is elastic strength. This is the ability of muscles and tendons to store energy in a stretch and utilize it in the following contraction. This process, called the stretch-shortening cycle (SSC), is what causes a higher jump from an approach than from a standstill. (Quick note: Lengthening muscle contraction is called eccentric, shortening is concentric, static is isometric. 59fifty hats wholesale , The SSC uses all three in quick succession) T

he human body naturally uses a countermovement before powerful motions in order to take advantage of this elastic strength. When you squat down to jump or pull your arm back to throw, you are using elastic strength to add force to the motion. The trick is that the desired motion must immediately follow the stretch to prevent the energy from dissipating. To demonstrate this, perform a natural jump from a standstill and take note of how high you get. Then do a jump but pause for a second in the crouched position before exploding upward. The second jump should not be as high, because the energy from the drop into the crouched position dissipates during the pause. The term for the muscle contraction involving a stretch followed by fast shortening is plyometric. Exercises that use this type of contraction have been labeled "plyometrics. oakley sunglasses sale , " This type of training is what increases elastic strength.

Vertical jump training needs to be tailored to the individual strengths and weaknesses of an athlete in the areas that have been mentioned. Therefore, it is incorrect to offer a single program and guarantee a certain result to anybody who tries it. A basketball player who cannot squat his own bodyweight will hardly benefit from a plyometric program, and a bodybuilder who squats twice his bodyweight will experience little gain from adding 20 pounds to his max squat. An effective training plan must take into consideration all the facets of vertical jumping. That is why on my vertical jump training site I provide methods for evaluating yourself, so you know which areas you most need to work on. This is far superior to just giving you common exercises and assuming they will be effective. .
