In the world of physical education and sports there are many tests or tests that are used to measure the physical condition of people. One of these tests is used to measure physical endurance and is known as Course-Navette . It is an ideal test to be administered in students who are in high school as it is a simple way to evaluate the physical power of students.

What is the Course-Navette?

The Course-Navette or Pi or Léger test as it is also known is a type of physical test that is used to measure the physical resistance of people which consists of repeatedly traveling the distance that exists between two points placed at 20 meters from each other.

What does it consist of

The Course-Navette is one of the best-known physical endurance tests in sport. This test basically consists of going and coming from one place to another in order to measure the aerobic capacity and oxygen consumption of an individual. It is based on repetitive displacement covering a distance that will be located between two specific points which must be located at a distance of 20 meters from each other.

Course-Navette Features

Some of the main characteristics of the Course-Navette are the following:

  • It is a type of cardiorespiratory endurance test .
  • It is done repeatedly and progressively in a short course.
  • It is a test that measures a person’s ability to exercise .
  • It is used frequently by physical education teachers , especially for high school or college students.
  • It is also used by professional athletes and is in fact in some places a mandatory test.
  • The firefighters , police forces and guards so usually must perform this type of test.
  • Testing on dirt or sandy soils is not ideal .

Story

The Course-Navette or Léger test was invented by a professor named Luc Léger who taught at the University of Montreal who specialized in the study of performance and physical condition in the early eighties. In 1982 a better version of the test was established and the first version published in 1983 consisted of periods that had a duration of two minutes which had to be carried out at a speed of 8 kilometers per hour .

In 1988 , a new edition was made for the test and a transition between the sounds was added which had a duration of one minute, also establishing the optimal speed of 8.5 kilometers per hour . On this occasion, the test was published under the name of “the multistage 20 meters Shuttle run test for aerobic fitness “, which in Spanish means “20-meter race test in stages to test aerobic fitness”

What is it for

The Course-Navette test is a test that basically serves to measure and evaluate the physical resistance that a person has as well as the resistance of the cardiac and respiratory system of the person who performs it.

How the Course-Navette is done

To be able to carry out this type of test, you will need very comfortable clothes first , preferably sports clothes , a lot of motivation and a track that is 20 meters long or a specific place well paved where two points can be placed with the same distance. The main objective then will be to travel this determined distance many times and then see how a person can resist the race taking into account the number of times and the speed .

To do it, you must also make use of a whistle by the person who performs the test, this is used to indicate the time you have to run the straight, at the beginning, the whistle will be made softly, while the participant will increase the speed of the race so progressive about 0.5 kilometers per hour per minute and as time passes, the sound becomes more often so the pace that leads the person performing the test should increase as does the sound . Usually at the end of the test, it is possible to reach an approximate speed of 20 kilometers per hour.

The test can end when the participant fails to finish the 20 meters twice in a row or when the person doing the test decides to surrender . Depending on the place where the participant has stopped, an assessment can be made by means of tables that specify an assessment, depending on age and sex .

Formula

The formula in this test is used to measure the speed that can be reached during the test and to know it, it is necessary to find the maximum volume of oxygen or VO2. The formula that can be used is the following:

VO2 Max = 5.857 x Speed ​​(Km / h) – 19.45

Table

In order to know the results of the Course-Navette Test, tables are used which are based on the age and sex of the person participating. In these tables the age reaches 18 years and meters traveled are not counted but rather a level system is used. The tables are as follows:

Guys Girls

Period

There is also a table by means of which distance and speed can be measured and it is based on stages, this is the following:

Course Navette board

1 8.5 km / h 7 140 meters
two 9 km / h 8 300m
3 9.5 km / h 8 460m

Importance of the Course-Navette

The Course-Navette test is a very important test especially for educational centers as one of the ideal mechanisms through which the aerobic capacity of adolescents can be correctly evaluated . It can also be used by people who want to know their physical condition or to improve it over time.
