Yo-Yo Endurance Test

Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made but in the analysis we need to bear in mind the factors that may influence the results.

There are two versions of the "Yo-Yo Endurance Test" developed by Bangsbo (1994)[1] which are both similar to the Beep test. The version one test, designed for recreational players, is the same as the standard Beep test. Version 2, designed for elite players, starts at a higher running speed and has different increments in speed.

Objective

The objective of the "Yo-Yo Endurance Test" is to monitor the development of the athlete's maximum oxygen uptake (VO2max).

Required Resources

To undertake this test you will require :

  • Flat non-slippery surface
  • 30 metre tape measure
  • Marking cones
  • The Yo-Yo Endurance test CD
  • CD Player
  • Recording sheets
  • Assistant

How to conduct the test

This test requires the athlete to run 20m in time with a beep from a CD recording. The athlete must place one foot on or beyond the 20m marker at the end of each shuttle.

  • The athlete warms up for 10 minutes
  • The assistant measure out a 20 metre section and marks each end with marker cones
  • The assistant starts the CD and the athlete commences the test
  • The assistant keeps a record of each completed lap (20m)
  • If the athlete arrives at the end of a shuttle before the beep, the athlete must wait for the beep and then resume running
  • If the athlete fails to reach the end of the shuttle before the beep they should be allowed 2 or 3 further shuttles to attempt to regain the required pace before being withdrawn
  • The assistant records  the number of laps completed by the athlete when they are withdrawn

Yo-Yo Test

Analysis

Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement.

Target Group

This test was developed specifically for soccer players, though it is suitable for similar sports where the athlete's participation is intermittent. The test is not suitable for individuals where a maximal exercise test would be contraindicated.

Reliability

Test reliability refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Reliability will depend upon how strict the test is conducted and the individual's level of motivation to perform the test. The following link provides a variety of factors that may influence the results and therefore the test reliability.

Validity

Test validity refers to the degree to which the test actually measures what it claims to measure and the extent to which inferences, conclusions, and decisions made on the basis of test scores are appropriate and meaningful. This test provides a means to monitor the effect of training on the athlete's physical development.

Advantages

  • Minimal equipment required
  • Simple to set up and conduct
  • Can be conducted almost anywhere

Disadvantages

  • Specialist equipment required
  • Assistant required to administer the test

Test Software

This test is available from Bitworks (on their site see the paragraph on "Team Beep Test Software for PC") and is also available as an App ("Team Beep Test") for the iPhone.
