Vertical jump is best described as the ability to raise one's center of gravity higher in the vertical plane solely with the use of one's own muscles. Muscle (from Latin musculus, diminutive of mus "mouse" is contractile tissue of the body and is derived from the

In other words, vertical jump is a measure of how high an individual or athlete can elevate off the ground from a standstill. A sportsperson ( British and American English) or athlete (principally American English is any person who participates regularly in a Sport.

The vertical jump test ultimately determines how "athletic" a considered athlete really is.

Places where vertical jump measurements are used

Usually, vertical jump measurements are used primarily in athletic circles both to measure performance and as something athletes brag about among themselves. The most common sports in which one's vertical jump is measured are track and field, basketball, football, and volleyball, but many sports measure their player's vertical jumping ability during physical examinations. Sport is an Activity that is governed by a set of rules or Customs and often engaged in competitively Basketball is a team Sport in which two teams of five active players each try to score points against one another by propelling a ball through a 10 feet (3 m Football is the word given to a number of similar Team sports all of which involve (to varying degrees kicking a Ball with the foot in an attempt to score a Volleyball is an Olympic team sport in which two teams of 6 active players (5 normal players and one 'libero' are separated by a net that is usually four feet

How to measure vertical

The simplest method to measure an athlete's vertical jump is to get the athlete to reach up against a flat wall, with a flat surface under his feet (such as a gym floor or concrete) and mark off the highest point he can reach flat-footed. (this is referred to as "standing reach"). Then, instruct the athlete to take several jumps from a standstill, marking off the highest point he can reach. Next, measure the distance between the two. This is the athlete's standing vertical jump.

The method described above is the most common and simplest way to measure one's vertical, but other, more scientifically accurate methods have been devised. A pressure pad can be used to measure the time it takes for an athlete to complete a jump, and then using a kinematics equation (h = g*t^2/8), the computer can calculate his vertical jump based on the time in the air. Using this method, an athlete can "cheat" by pulling his/her knees up to extend hangtime.

A second, more efficient and correct method is to use an infrared laser placed at ground level. Infrared ( IR) radiation is Electromagnetic radiation whose Wavelength is longer than that of Visible light, but shorter than that of A laser is a device that emits Light ( Electromagnetic radiation) through a process called Stimulated emission. When an athlete jumps and breaks the plane of the laser with his hand, the height at which this occurs is measured.

Devices based on United States Patent 5031903, "A vertical jump testing device comprising a plurality of vertically arranged measuring elements each pivotally mounted. . . " are also common. These devices are used at the highest levels of collegiate and professional performance testing. They are comprised of several (roughly 70) 14-inch prongs placed 0. 5 inches apart vertically. An athlete will then leap vertically (no running start or step) and make contact with the retractable prongs to mark their leaping ability. This device is used each year at the NFL scouting combine.

Common misconceptions about vertical jump

The most common misconception about vertical jump is that the measurement displays the athlete's ability to elevate off the ground from a run-up, contrary to from a standstill. The effect of this misconception is that many athletes will quite grossly inflate their vertical jumps. Also many athletes have learned to "cheat" the existing systems. The vertec can be cheated by not reaching as high on the initial measurement commonly referred to as "shrugging your shoulders". Jump pads can be cheated by lifting your knees, or even hanging on to them until the very last moment. Since jump pads rely on hangtime, they are easily cheated.

Increasing vertical jump

One of the most frequently asked questions in the athletic world is "How can I increase my vertical jump?". A higher vertical jump has obvious advantages in several different kinds of sports such as basketball and volleyball. Basketball is a team Sport in which two teams of five active players each try to score points against one another by propelling a ball through a 10 feet (3 m Volleyball is an Olympic team sport in which two teams of 6 active players (5 normal players and one 'libero' are separated by a net that is usually four feet

There are many different aways to increase one's vertical jump, with much controversy on which method is the most effective. What follows are scientific and physical breakdowns of how to improve the height of one's vertical jump.

A more scientific breakdown of vertical jump is required to comprehend methods to improve performance.

Vertical jump is a measure of how far off the ground one can elevate one's own body using only the power generated by their muscles.

In physics, power can be computed using the following formula :

Power = Work / Time

In relation to sports, power is better described by the equivalent expression:

Power = Strength * Speed

Therefore, to increase power (and consequently vertical jump), an athlete must train to improve both strength and speed.

Strength can be increased using traditional strength training, with emphasis on the posterior chain (or "p-chain") which consists of the hamstrings, calves, lower back and glute muscles. Strength training is the use of resistance to muscular contraction to build the strength, anaerobic endurance and size of Skeletal muscles There The posterior chain is a group of muscles tendons and ligaments on the posterior kinetic chain of the body In Human anatomy, a hamstring refers to one of the Tendons that make up the borders of the space behind the knee The calf or gastroc-soleus is a pair of Muscles mdashthe gastrocnemius and soleus &mdashat the back of the lower Human leg. "Back" redirects here For other uses please see Back (disambiguation. The gluteus maximus' (or glutæus maximus) is the largest and most Superficial of the three Gluteal muscles. Muscle (from Latin musculus, diminutive of mus "mouse" is contractile tissue of the body and is derived from the Studies have shown that the majority of force generated during a vertical jump is generated by these muscles, and most importantly the quadriceps which are not part of the p-chain but rather the anterior chain. "Quads" redirects here For other uses see Quad The quadriceps femoris ( Latin for "four-headed of the femur" also Beach muscles refer to a group of Muscles that lie on the front of the human body

Therefore, arguably the two most important max strength lifts for improving vertical jump are the full back squat and the deadlift. The squat is a lower body exercise used in Strength training. The deadlift is a Weight training Exercise where one lifts a loaded Barbell (or in the case of the trapbar deadlift a loaded Trapbar)

Speed in the vertical jump is a measure of how fast one can exert force. In the vertical jump, there is a very short time period in which force can be generated to use in a vertical jump(0. 2s). Hence, it is very important for an athlete to be able to exert the maximum force possible in the shortest amount of time. Speed training reduces the "time" portion of the power equation, resulting in more overall power.

Speed training consists of two elements: Plyometric exercises (exercises which allow you to absorb the more energy during the countermovement, or eccentric contraction, of an explosive movement such as jumping or sprinting) and explosive training such as jump squats or power cleans. Plyometrics is a type of Exercise training designed to produce fast powerful movements and improve the functions of the nervous system generally for the purpose of improving A muscles contraction (also known as a muscle twitch or simply twitch) occurs when a Muscle fibre generates tension through the action of Actin Jumping or leaping is an ability that most Humans and many Animals share to some degree Sprints are short running races in athletics. They are roughly classified as events in which top runners will not have to "pace themselves" but can run as fast as The squat is a lower body exercise used in Strength training.

An important fact to note is that plyometric and explosive exercises are not necessary until an athlete has built up a fairly strong strength base (commonly set between 1. Plyometrics is a type of Exercise training designed to produce fast powerful movements and improve the functions of the nervous system generally for the purpose of improving 5 and 2 times an athlete's bodyweight in the full squat and deadlift exercises). The squat is a lower body exercise used in Strength training. The deadlift is a Weight training Exercise where one lifts a loaded Barbell (or in the case of the trapbar deadlift a loaded Trapbar) The reason for this is that even if the time portion of the power equation is reduced significantly, the overall power will still be a lower number if the force portion of the equation is neglected.

Flexibility of the Achilles Tendon has also been known to increase the vertical jump of an athlete. The Achilles tendon (or occasionally Achilles’ tendon) also known as the calcaneal tendon or the tendocalcaneous, is a Tendon of the posterior Caution must be used, though, since tearing of the tendon can occur.

Exercises used by professional trainer Joe DeFranco

Flexibility (achieved through stretching) also increases the vertical leap. The term can also refer to the stretching of Canvas on a frame.

There are many vertical leap enhancement programs available on the internet. You should be weary about the programs claims before buying and do your own research. An informative review site like e-reviewers. com/vertical can be helpful in making your decision by giving you information that is not available on the program sites themselves.
