A  vertical jump  or  vertical jump  is the act of raising the center of gravity as high in the vertical plane only with the use of the muscles themselves 

Types of vertical jump

The vertical jump is divided into two different types:

  • Standing vertical jump:  Refers to a vertical jump made from scratch, without measures that are involved at all.
  • Vertical jump run:  Refers to a vertical jump after a focus or run to help add energy for the jump in an effort to improve the vertical jump.

In general, the vertical jump is the one used as an official measure for athletes.

When vertical jump measurements are used

Vertical jump measurements are used mostly in sports circles, both to measure performance and athletes somewhat boast among them. The most common sports in which a vertical jump is measured are track and field, basketball, soccer and volleyball, but in many sports the vertical jump capacity of its players is measured during physical exams. In addition, individual and multiple vertical jumps are sometimes used to assess muscular strength and anaerobic power in athletes.

How to measure vertical jumps

According to Vermont’s Jimmy Winslow, the simplest method to measure an athlete’s vertical jump is to get the athlete to reach a flat wall, with a flat surface under their feet (such as the gym or concrete floor) and mark the highest point he / she can reach with flat feet (this is known as “getting on foot”). Then, the athlete to have several jumps from a stalemate, marking the highest point he / she can reach. Then measure the distance between the two. This is the standing vertical jump athlete and with this you can control the tracking of any increase in the vertical jump.

The method described above is the most common and simple way to measure vertical jump, but other scientifically more precise methods have been invented. A pressure pad can be used to measure the time it takes for an athlete complete a jump, then using a kinematic equation (h = g * t  2  /8), the computer can calculate its vertical jump depending on time in the air. Using this method, an athlete can “cheat” by pulling his / her knees to extend hangtime.

A second, more efficient and correct method is to use an infrared laser placed at ground level. When an athlete jumps and breaks the plane of the laser with his / her hand, the height at which this occurs is measured.

United States-based patent devices 5031903, “a vertical jump test device, comprising a plurality of vertically arranged elements each pivotally mounted measurement …” are also common. These devices are used at the highest levels of university and professional performance tests. They consist of several (approximately 70) 14-inch teeth placed 0.5 inches in vertical distance. An athlete will take a vertical jump (do not start running or stepping) and make contact with the retractable legs to mark their jumping ability. This device is used every year in the NFL Scouting Combine.

Vertical jump as an evaluation

A vertical jump of 40 inches (1.0 m) or more is considered exceptional. Some athletes have even recorded vertical jumps over 50 inches (1.3 m), which is extremely rare.

Misconceptions about vertical jump

The most common mistake about vertical jumping is that the measurement shows the athlete’s ability to rise from the ground from a previous phase, against a stop. The effect of this error is that many athletes grossly inflate their vertical jumps. Also, athletes have learned to “cheat” existing systems. The Vertec can be fooled by not reaching the top in the initial measurement commonly known as “shrugging one’s shoulders.” Jump pads can be fooled by an elevation of the knees, or even hanging from them until the last moment. Since jump pads are based on hangtime, they are easily fooled.

On the other hand, in practical terms, an execution approach is often properly observed. For example, in volleyball, the defenders in the net waiting to put a block against an attacker have stopped the jumps, but the attacker will have a functioning focus.
